Experience with Thick Driver - Problems with threads?

Hi!
I was wondering if anybody has experienced some problems
in the past regarding the use of the JDBC thick client?
There are some "rumors" in our department that (at least
two years ago) the contents of threads got mixed up!
Have you heard of such errors?
We have to make a decision at the moment wether to use
thin or thick client. We use Oracle 8.1.7. and a
Websphere App Server 4.04.
Any comments about the reliability of thick drivers?
Thanks, any help is highly appreciated!
Cheers,
Steffen

Hello Steffen,
I have been using Oracle's JDBC Think Client for some time and havent faced any problems yet. Atleast, havent faced any problems related to Threads.
Hope this helps.

Need help with threads?.. please check my approach!!

Hello frnds,
I am trying to write a program.. who monitors my external tool.. please check my way of doing it.. as whenever i write programs having thread.. i end up goosy.. :(
first let me tell.. what I want from program.. I have to start an external tool.. on separate thread.. (as it takes some time).. then it takes some arguments(3 arguments).. from file.. so i read the file.. and have to run tool.. continously.. until there are arguments left.. in file.. or.. user has stopped it by pressing STOP button..
I have to put a marker in file too.. so that.. if program started again.. file is read from marker postion.. !!
Hope I make clear.. what am trying to do!!
My approach is like..
1. Have two buttons.. START and STOP on Frame..
START--> pressed
2. check marker("$" sign.. placed in beginning of file during start).. on file..
     read File from marker.. got 3 arg.. pass it to tool.. and run it.. (on separate thread).. put marker.. (for next reading)
     Step 2.. continously..
3. STOP--> pressed
     until last thread.. stops.. keep running the tool.. and when last thread stops.. stop reading any more arguments..
Question is:
1. Should i read file again and again.. ?.. or read it once after "$" sign.. store data in array.. and once stopped pressed.. read file again.. and put marker ("$" sign) at last read line..
2. how should i know when my thread has stopped.. so I start tool again??.. am totally confused.. !!
please modify my approach.. if u find anything odd..
Thanks a lot in advance

Hello,
I have no experience with threads or with having more than run "program" in a single java file. All my java files have the same structure. This master.java looks something like this:
---master.java---------------------------------------------------
import java.sql.*;
import...
public class Master {
public static void main(String args []) throws SQLException, IOException {
//create connection pool here
while (true) { // start loop here (each loop takes about five minutes)
// set values of variables
// select a slave process to run (from a list of slave programs)
execute selected slave program
// check for loop exit value
} // end while loop
System.out.println("Program Complete");
} catch (Exception e) {
System.out.println("Error: " + e);
} finally {
if (rSet1 != null)
try { rSet1.close(); } catch( SQLException ignore ) { /* ignored */ }
connection.close();
-------end master.java--------------------------------------------------------
This master.java program will run continuously for days or weeks, each time through the loop starting another slave process which runs for five minutes to up to an hour, which means there may be ten to twenty of these slave processes running simultaneously.
I believe threads is the best way to do this, but I don't know where to locate these slave programs: either inside the master.java program or separate slave.java files? I will need help with either method.
Your help is greatly appreciated. Thank you.

T500 Problems and experiences with Lenovo's technical support / EZServ

After some issues and numerous calls to Lenovo's Technical Support, I just thought I would share my experiences here.
First off, I currently own a ThinkPad T500, which was designed to be a replacement for my older ASUS laptop.
While the ASUS laptop is still running okay, I have had a hard time trying to get the company to properly warranty the laptop. (they would make falsified claims that nothing is wrong with the laptop, so that they would not have to replace any parts - and when they do replace parts, they would simply create another problem and totally ignore the described problem.) The experiences were so stressful and disgusting such that I am sick of arguing with the company any further. My decision on the ThinkPad was based on that IBM/Lenovo is designed to serve business class customers and theoretically should have "business-class support". For this very reason, I have added the best warranty service they was offered to me at the time (3yr onsite + accidental). I am just guessing at that time I just wanted to get away from small companies and go to a company that would back their customers' laptops.
As soon as I got my hands on a T500, however, I have noticed that something is wrong with the card reader. Apparently the reader on the machine would not read SDHC cards (it does read SD cards, however.) This is a problem because I only use SDHC cards and the machine was not able to read any of them. As the card reader controller is manufactured by the same manufacturer (Ricoh) and my older ASUS laptop was able to read SDHC cards, I thought something odd was going on with my machine. This was also based on the evidence that other T500 owners were able to read SDHC just fine.
In addition to the card reader, I was also having troubles in which the machine would freeze whenever Nero Burning ROM (a CD/DVD authoring software) is used.
My first support call to Lenovo was not that pleasant, given that I was placed on hold for 20 minutes when the rep was looking up specs for SHDC compatibility. The rep also said that they would not troubleshoot 3rd party software and would not help me on the issue. I was also told that I should also call back during "regular business hours (apparently until 5pm EST, or 2pm PST (my time)" (despite that the technical support hotline is open 24/7) so that a supervisor can handle my case. This makes it very difficult for me to get to someone with any authority as I am usually busy throughout the day until late afternoons (~4pm PST -> 7pm EST).
Nevertheless, my second call to Lenovo was much more pleasant. The rep handled my case in a timely fashion and promptly provided replacement parts indicated by my problem. (Onsite motherboard replacement for the card reader, and a separate shipment for the DVD-RW drive). Turns out that the motherboard replacement did fix the SDHC issue, although the freezing problem was not caused by hardware failures, but rather a faulty driver that was corrected after Lenovo released an update months later on the Intel SATA controller drivers.
Five months later, after having to use a broadband WWAN card for my work, I also started to notice there is something wrong with the broadband WWAN card. The card used is the Ericsson F3507g card (or the AT&T broadband WWAN option). Not only would the connection be very flaky, it would also drop connections fairly frequently. It seems that a SIM card pull to another card would result in a perfect connection and ever since I have been using an addon card instead to use the Internet. When I confronted Lemovo with the problem, the experience was worse than the first one. I have made at least six service calls to Lenovo and everytime the reps will waste my time with basic troubleshooting which I told them repeatedly that I have already done (I have even reinstalled the OS but it seems that it does not matter to the reps). Here are some things that are repeated over and over:
1) Can you uninstall the Power Manager Driver and the Wireless WAN drivers and reinstall them?
2) Can you go on to our website and download the WWAN drivers (document ID: MIGR-70000 - I even remembered this number since it was repeated so many times) - and the Power Manager Driver and reinstall it?
3) Can you go to Device Manager (the rep would go step by step to it even though I told him I already know how to get there), and see if there are any "bangs" (exclamation marks) on any of the devices?
4) Since you were able to connect to the AT&T network, then from the hardware standpoint there is nothing wrong with your card. This indicates there is a software configuration or a driver problem. (I have been trying to acquire the latest drivers but what I have was already the latest)
5) Since your card could connect to the network, you should contact your provider for help. (AT&T blames it on the card)
6) I'm sorry but there is nothing I can do to help you. You should contact your provider about the card (despite that I acquired the card from Lenovo and not from them)
7) Are you sure that your card is activated properly? It doesn't show in our systems that the card has been activated properly. You will need to call both AT&T and the Lenovo activation hotline (whatever this is) to have your card work properly. (I have never heard of this before)
Despite telling these reps I have an addon card that works perfectly and that I have done all the basic troubleshooting already, none of them are really willing to give me a replacement card. They would either request that I send my computer back to the depot (which I do not want to do since I use this laptop everyday and that's why I have onsite warranty), fail to help me, or transfer me to someone else that makes me do all the troubleshooting all over again. (Every call I made to Lenovo can be said to be composed of at least 20 minutes of basic troubleshootings with the end result of not being able to help)
After having the case escalated to a team leader, I was told that someone would give me a call within a few hours since their team leader is with another customer. Result? No callbacks. Not within a day, nor two.
Called Lenovo again, they apologized, but samething happened - supervisor on the line - promised another callback by a supervisor - but nothing, nada!
Called Lenovo a third time - was again told the same thing, but I am not falling for that anymore - the rep finally agreed to give me a replacement, as well as as to send out a technician that would fix the LCD cover that is starting to get loose on one side.
At that time, I was so frustrated and this reminds me of the pain I have went through with my old ASUS laptop and their grumpy customer service. It just seems to me that it has to be that difficult to have anything resolved or fixed. (What is especially frustrating is that the basic reps do not have any authority to make any decisions, 90% of the time I will need to be transferred to a supervisor of some sort before my case can be handled successfully - which is hard at times given that I only have until 2pm PST to call them)
Received replacement, but did not fix issue. I have noticed that the GPS (which was part of the WWAN card) also has problems getting adequate signals for a 3D Fix. I have once again called Lenovo, this time raising the concerns with the GPS and seeking for help. Along with the basic troubleshooting, here is what Lenovo has to say about the GPS issue which frustrates me even more:
1) uh, G..P..S? what GPS? (most reps I call say this, shows me that they either don't know what a GPS is or know that there is a dedicated GPS builtin on the Ericsson module. Perhaps they don't even know that ThinkVantage GPS existed)
2) You will need to have active service in order to use GPS (I do have active service, but nevertheless that statement is false since a 3D fix can be successfully acquired with a dummy card - I guess the rep has no idea what he/she was talking about)
3) That's a software issue - you need to call AT&T and tell them about the problem (Again, I guess the rep has no idea that the GPS is not linked to AT&T's networks - there is a dedicated GPS on the card that allows the ThinkVantage GPS tool to acquire proper GPS signals) (Also, why would AT&T troubleshoot a tool that Lenovo made called ThinkVantage GPS? - I don't get it)
4) You need to uninstall, and then reinstall the Power Manager driver and also the latest WWAN drivers. (I did that, did not work - I have told them I even reinstalled the OS from scratch)
5) You need to go uninstall, and then reinstall the Wireless LAN drivers (although I am talking about wireless WAN, not LAN)
6) There are two wireless adapters in your laptop? Are you sure about this?
7) LAN, or WAN? What are you referring to? (I guess some reps are not aware what WWAN means)
After dealing with the numerous reps that have no idea what I was talking about, I have decided that I would just take the machine into depot, which would give me a chance to explain the other issues I have with the machine as well.
Here are some of the issues I am having with my T500 right now (please comment if you have the same issues or perhaps have a possible solution/workaround for it)
1. The left side of the LCD cover has a pressure point, which causes the cover to dislodge from the rest of the panel slightly when pressure is applied from the back side of the cover. (Could be caused by closing the lid, for example) - IBM technician applied some adhesive to the inside, which helped it from dislodging, although the left side is still a little filmsy compared to the right.
2. This error randomly pops up at infrequent intervals: "Display driver igfx stopped responding and has successfully recovered."
The latest GFX driver is installed and all updates have been installed. OS has been reinstalled but problems still occurs infrequently.
3. This error also pops up at infrequent intervals: "Active protection is not functioning as system detected the abnormal sensor status. To diagnose the sensor device, run PC DOCTOR DOS - HDD Active Protection Test and if it still shows, contact Help and Service for repair." The only problem is, my laptop only came installed with PC Doctor 5 for Windows and when I run it"
I ran a sensor check in DOS using the diagnostic CD and the sensor checked out okay. This error seems to happen mostly after I changed a setting in the Active Protection System software. (ex. changing the suspend time, etc)
4. By default, the internal microphone does not work. In order for the internal microphone to work, the Advanced multi-stream mode must be enabled in the SmartAudio control panel. If both redirection options are enabled, the internal microphones and the speakers would then work normally. However, the hotkey controls on the ThinkPad would not control the right device when headphones are plugged in (since headphones are classified as its own device when the Advanced stream mode is enabled) - Mute and volume controls thus only controls the internal speakers' volume, and have no control whatsoever when headphones are plugged in.
5. The brightness on the T500 is rather dim. I am not sure if that's how the monitor is, but I can hardly see anything unless the display brightness is close to the max setting. I have the 1680x1050 matte screen.
6. The WWAN card does not make a stable connection to the network and ThinkVantage GPS does not acquire a 3D Fix even when under direct sky for >20 minutes. What is interesting though is that if I turn off the monitor screen (Fn+F3) or close to lid, the WWAN connection will be very stable and GPS will function normally (acquire fix usually within 2-3 minutes). If the monitor/screen is turned back on after a GPS Fix is acquied, the signals will quickly deteriorate and the updates will either become delayed/inaccurate or a fix will be lost. The brighter the screen, the harder it is to get a fix or a stable connection. (At the max setting it is almost impossible to get a fix while at the lowest brightness a very weak fix can be acquired - this is the case even many sattelites have been detected) Perhaps something with power consumption? Or the LCD drawing too much power?
7. Although it does not happen very frequently, pressing Fn+F3 to turn off the display might cause the LCD to flicker on and off non-stop.
8. This used to happen more with the older version of the Lenovo Fingerprint Software - but sometimes the software tends to get stuck at the welcome screen after returning from sleep/suspend/standby mode. The screen will remain at Please Wait forever and a hard restart will be required to get back into Windows.
9. At frequent intervals the sound from the internal speakers would stop working and only the headphones would work. The sound might, however, come back if I leave the headphones plugged in long enough and unplug them. Restarting the Windows Audio service will temporarily restore audio but the same issue tends to happen again soon after that. Driver issue? (I am not sure if it's relevant, but I tend to put my computer to sleep instead of shutting it down)
I have explained all of these issues on a piece of paper that I have included in my shipment to Flextronics. I have also included in big letters to make sure that they do not send the laptop to the address where they originally sent the "box" to. This is because I am only at that address a few days during the year and I don't plan to be there most days during the year.
On the first day, it seemed that the status changed from "Machine being repaired" to "Hold for customer information".
Apparently I missed a call from a number with an area code of 901 (which is Memphis, TN - I assume this is Lenovo's support center, since this is where the package was sent to). No messages were left on the voicemail. Called the number back, but was however told that I dialed the wrong number and no one has ever called me on this number (the lady on the phone was quite rude too) I then called the 800 EZServ number instead, turns out that they wanted one of my passwords which I gave them.
The evening after I saw that the machine was successfully repaired and that it is being shipped back to me. However, no tracking number was provided. (There still isn't a tracking number on the EZServ status page)
Hoping that my machine was repaired in good condition, I took a day off so I would be able to wait for UPS to deliver my laptop.
Such that I have something to work with, I called the EZServ # and see if they had a tracking number for my shipment. At the same time, I asked what components were replaced and/or what components were installed to the system. To my surprise, they reimaged the whole system and I was not even informed about this at all! (I do understand I checked the Yes box in the problem description page, but I felt that it was important that the repair center let their customers know before their data will be destroyed - luckily I imaged my laptop right before I shipped it out so I have a copy of my data) In addition, it also seemed that they did not read any of the pages I enclosed in the shipment since nothing about the WWAN card was ever mentioned, despite special emphasis placed on this when I called Lenovo to have my computer sent back. It seemed that the rep only recorded one of the problems I listed above, which was unsatisfactory.
The repair process was disappointing, as I have included in my problem description that I have previously tried reinstalling the whole OS from scratch and the problems did not go away. Reimaging the system will also probably have no effect on the problems I have described in the problem description.
What is more surprising to me though was that they totally skipped the notation I put on to have the notebook shipped to an alternate address relative to the box address. To make this impossible to miss, I miss drew a big * and circled it many times so that anyone would see it if they were reading the sheet. I found out shortly after checking on the UPS website that the city the package was being shipped to was that of the wrong address, and not the city of that of the alternate address. I was horrified after knowing that the package would not arrive today but yet I still took a day off work. (How disappointing?!)
Again and again, I called EZServ to see if I can have the package intercepted so it can be delivered to the right address. An intercept was placed on the package, although I received a call 30 minutes later from UPS saying that the intercept failed since the package has already been delivered. UPS also told me there is no way the people living there can simply return it and continue on with the intercept. Not happy with what I am hearing, I called EZServ and see if they can set up a pickup request to have the package delivered to my address. The first rep hanged up on me shortly she answered. The second rep called UPS, placed me on hold for more than 20 minutes, then hanged up on me. The third rep called UPS, and told me that they have esculated the case and that "UPS will handle everything", whatever that means. (she refused to disclose any more details). She told me that I would be receiving a call from her shortly on the details on the upcomings and promised that I would be receiving my laptop back. As with Lenovo, I didn't receive any callbacks. I called EZServ once more, and all they would say is tell me to wait. Sick and tired of waiting and calling and not getting anywhere, I drove 100 miles to where they shipped my laptop and picked it up there. I just don't know whether to trust the EZServ people anymore....
As far as the laptop goes, I didn't have time to open the box or to test it yet. But I will let you all know once I have taken a look at the results.
While the past experiences have been painful, I haven't lost all hope in Lenovo yet - although I really think that the customer service can really improve on certain levels.
Please give me advices on what to do next!
Thanks for reading this!

Hard drive problem with Pavillion DV9722EG notebook

I have the a.m. notebook with a single 250GB hard drive installed, and there is an empty slot for a second hard drive.
I tried to install a second hard drive, but the hard drive is not recognised in any way in BIOS... the BIOS is the latest version from here:
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-69499-1&lc=en&dlc=en&cc=us&product=3668082&os=2093&lang=en
I really would need to install a second hard drive... and if anyone knows how to solve this problem, I would really appreciate any hint!

Sorry to say you are not alone in your problems:
Other thread
I have not actually tried to put a second drive in a dv9000 but based on other threads there are people who have success with it. I recall one guy had two hard drives and only one of the two would work in the second slot. Others have completely failed to get a second drive working as you can see above. I own a dv7 and have had no issues installing a second drive in it.

SQL Developer 3.2 crashes with java error when using OCI/Thick Driver

I just installed SQL Developer 3.2 on my linux desktop. SQL Developer crashes with a java error when I select a database from the object tree.
When I check Use OCI/Thick driver the application will crash when I navigate to the tree and open a database.
The app does not crash then I have Use OCI/Thick driver unchecked.
Here are some details of my environment:

I also had the problem of SQL Developer crashing when using OCI/Thick driver but I've managed to solve it. My configuration is:
- Windows 64-bit
- Java 64-bit (1.6.0.34)
- SQL Developer 3.2.09 64-bit
- OCI Instant client 11.2.0.3 64-bit (without installation).
The thing that solved the problem was copying two files, ojdbc5.jar and ojdbc6.jar, from Instant client installation folder to JAVA_HOME/lib/ext folder+.
After that, I haven't had a single crash or error message.
The same trick that solved the problem on 64-bit installation also solved the problem on another windows computer with 32-bit SQL Developer installation.

Experience with Iomega 250GB Ext Drive & Lacie PCMCIA to Firewire 800?

Hi!
I bought an Iomega 250GB Ext. Hard Drive and I'm contemplating buying a Lacie PCMCIA to Firewire 800 PC card for my PowerBook G4 (the G4 is older and does not have built in Firewire 800 capability.) Has anyone had experience with this configuration? I'd like to know if there have been any problems trying to go with this configuration before I buy the Lacie card. If there are problems with this set-up then my best choice it appears would be to use the Firewire 400 port on the laptop and on the ext. drive. (There is also USB 1.1/2.0 capability.) Anyone with experience in this area please advise.
Thank you!
tenntooter

Hi t,
I haven't had experience with this setup, but ran across this test sometime ago. They tested the LaCie card you're looking at with a Ti 800MHz with no issues.
(There is also USB 1.1/2.0 capability.)
Take my word for it, you don't want to use USB1 (major slow) and to use USB2, you'd need to buy a PCMCIA card to USB2 adapter anyway. Even then, in real-world transfers, FW400 is faster than USB2, so if your FW port is working, there's no reason to go the USB2 route.

Any experience with LaCie Thunderbolt drive?

LaCie's thunderbolt drive is getting reasonably good reviews on the Apple store -- http://store.apple.com/us/reviews/H7150ZM/A.
Good, save for the fan noise. It sounds like in some units, for some people, it's intolerable.
Anyone here have experience with it? I'm considering it as my primary video editing drive.

1 TB, 7200. Only have 3-weeks experience but no problems so far. Huge improvement in FCP X performance. Attributed most of my problems with lock-up, dropped frames, beachball, etc. to disk drives. FCP X simply won't work reliably with USB, FW400 on my system. FW800 (pure) is okay. TBolt is better choice. LaCie has 2 drives inside metal case - significantly more drive noise than my WD FW800. Not a major issue for me but could be problematic if you're trying to record naratives while editing.

Powerbook G4 12" 867mhz with dvd/cd drive problems - please help!

Hello all,
Just realized this thread should have been in this section. I put it in the using your powerbook section. Sorry for the double post. I just wanted it to be in the right section.
I have just inherited a powerbook g4 from a family member who is upgrading to a new machine. It has dvd/cd drive problems. I'm totally new to OSX and a notebook machine and need some assistance. I've been briefly scanning the forums here and noticed problems with these drives on the model computer. Is there a way to fix this with an install of older software? Here is the problem, if I insert a cd into the super drive it mounts on the desktop, and itunes will play it but it skips and sounds very distorted. I haven't tried a dvd but was told it doesn't even see the dvds on the desktop. Here are the know specs on the machine:
867mhz
640 mb ram
mac os x 10.5.1
boot rom version 4.5.5f4
the burner info: matshita dvd r uj-015
firmware version: docb
Thanks in advance!

Good Morning Mac,
According to your posted specs for the 12" G4PB you have the bare minimum requirements for Leopard. Even Tiger (10.4.11) should have 1GB RAM for decent performance (see my signature specs).
An easily installed 1GB RAM stick can be obtained at either of these reliable vendors:
http://eshop.macsales.com/ or http://www.crucial.com/
However, we are getting ahead of ourselves. Try the following in this order:
Repair Disk Permissions with /Applications/Utilities/Disk Utility/Repair DP, then do the following:
Run Repair HD from original CD or DVD install disk ........
Insert disk and re-start holding down the 'C' key until you see the spinning gear.
At Installer level...... DO NOT CONTINUE
At top left, use 'Utilities' Menu for Tiger or later and go 'Disk Utility'
Select your HD volume with Operating system on...
Select First Aid tab then select Repair Hard Disk button
If "RED" errors are repaired, run again, until none are reported then +run again+ just to be sure you are OK
Do NOT continue with the Installer... QUIT the Installer and return to the Finder ......... Eject the Disc
RESTART ..... Repair Disk Permissions .... AGAIN!
Try the above stuff first .... if that doesn't help, we will get into the "RESETS" steps next!

Problem with Thread and InputStream

Hi,
I am having a problem with threads and InputStreams. I have a class which
extends Thread. I have created and started four instances of this class. But
only one instance finishes its' work. When I check the state of other three
threads their state remains Runnable.
What I want to do is to open four InputStreams which are running in four
threads, which reads from the same url.
This is what I have written in my thread class's run method,
public void run()
     URL url = new URL("http://localhost/test/myFile.exe");
URLConnection conn = url.openConnection();
InputStream istream = conn.getInputStream();
System.out.println("input stream taken");
If I close the input stream at the end of the run method, then other threads
also works fine. But I do not want to close it becuase I have to read data
from it later.
The file(myFile.exe) I am trying to read is about 35 MB in size.
When I try to read a file which is about 10 KB all the threads work well.
Plz teach me how to solve this problem.
I am using JDK 1.5 and Win XP home edition.
Thanks in advance,
Chamal.

I dunno if we should be doing such things as this code does, but it works fine for me. All threads get completed.
public class ThreadURL implements Runnable
    /* (non-Javadoc)
     * @see java.lang.Runnable#run()
    public void run()
        try
            URL url = new URL("http://localhost:7777/java/install/");
            URLConnection conn = url.openConnection();
            InputStream istream = conn.getInputStream();

AMD/ATI driver problems on a Dell laptop with attached dual monitors

I have a Dell Precision M4800 laptop with a docking station for two additional monitors. I'm shooting for a "big desktop" setup, with my laptop display and the two external monitors forming one large multi-monitor X screen.
When deciding which video driver I'd need, I did the usual:
$ lspci | grep VGA
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Venus XT [Radeon HD 8800M Series]
Which is weird, because the M4800 isn't shipped with 8800M cards. Rather, it's shipped with the AMD FirePro M5100 Mobility Pro (see above link) (also, too many "Pros", AMD...).
I tried the open-source driver, but I couldn't get both my external monitors working in tandem, so I went with catalyst-test, since the non-beta version of the proprietary driver doesn't support the 3.13 kernel (or my alleged 8800M series card, for what it's worth).
My display setup using catalyst-test is still far from ideal. My dual (horizontally adjacent) monitors reset to cloned/mirrored desktops after every reboot, and my machine refuses to show three monitors (dual monitors + laptop display), even with the 2GB of dedicated RAM in my graphics card (see above M4800 link). There's other miscellaneous annoyances as well.
Using hardinfo, I see that my VGA driver thinks it only has 256MB of RAM... which doesn't align with the M4800 specs. Is there a way to change this value?
Just today, I found the catalyst-firepro driver, which I think might be the correct driver for my laptop, at least given the specs on the M4800 from the website.
There's also the option of not using my AMD card at all, and just using the Intel graphics on my laptop. (I had to disable hybrid graphics in my BIOS to get any AMD-specific drivers to work). I'd like to steer away from this, due to the performance loss, but I'd be willing to make the change if the pros outweighed the cons.
As I see it, I have a few options:
AMD/ATI open source driver: Can't seem to get two monitors working, much less three...
catalyst-test: Any two monitors will work together, but not three. Other annoyances.
catalyst-firepro: Have not tested yet.
Intel open-source driver with AMD card disabled: Have not tested yet.
Can anyone who has had similar issues and/or hardware offer a best course of action which has worked for them? I know we're supposed to avoid "opinion" questions, but I think this is grounded enough in the scientific method to merit some helpful responses.
Any help is appreciated.
Thanks!

The last option to me is screaming catalyst-pxp at me, because that's one of the few options if you have integrated graphics and a discrete graphics card.
Let me get this straight: Can you disable the either or both of the Intel/AMD graphics in the BIOS settings? If so, but don't want to disable either, you might want to look at the hybrid graphics section of the wiki.
I know about powerXpress and I think I'd like to avoid it. My experience with hybrid graphics on other Linux distributions is that it's rather unstable or just plain unsupported. If someone can convince me otherwise, given their experience with hybrid graphics on Arch/Linux, I might reconsider.
I'm fairly certain I can enable either of my GPU's separately, but I'll have to check for sure next I reboot my PC.
The last option I mentioned because I thought the Intel drivers might be more robust than the AMD drivers, which have don't have a sterling reputation when it comes to supporting Linux (compared to nVidia anyways, who I know in the past have had good Linux support).

Hard drive problem with HP Pavillion dv7-4180us

Hard drive problem with my HP Pavillion dv7-4180us. Using Windows 7.
Boots up sometimes and very slow.
Appreciate any help.

Have you booted into the BIOS or Diagnostics Tool to run the Hard Drive Test?

Photoshop cs6 won't allow me to highlight my existing text layers. Does anyone have experience with this problem?

Photoshop cs6 won't allow me to highlight my existing text layers. I select the text tool and the text layer I want to edit, hover over text and each time I attempto to edit a new layer is created. Does anyone have experience with this problem?

Be sure you go to Adobe's Web Site and make sure there are no Updates for CS6
http://www.adobe.com
Remember if you have trouble with a software issue it is the software and not caused by the Mac you are using
Many users simply don't remember when you upgrade software you normally have to go to 3rd party web sites and update software as well.

Print driver problem with OS 10.4.6

I recently installed 10.4.6 and ever since have been unable to print via a network on a Lexmark Optra T614 (duplex). All was working fine until the upgrade to 10.4.6. I have downloaded a driver from Lexmark's website and successfully installed it to my system via the wizard - message was "you have successfully installed . . . ". However cannot find it to install through the Print Centre. I am running it through a router shared with a PC (Windows 2000). No problems at the Pc end. As I said prior to purchasing 10.4.6 all was working fine. I have tried to set up to print through the local network via the PC - without success. At one point (not sure what I did) actually got the Mac talking to the printer. The lights were activated and it made a few attempts but then cancelled out. I then tried something else and it didn't work, so now I am back to where I was when I started. Can you help with this one Greg? regards Ian

Hi Greg, Still no answer to my printing problem.
The Optra T driver is probably right.
I trashed the drivers and did a fresh download and reinsatlled. It is an Optra T driver.
Since you can't print using generic postscript, I don't think you
have a driver problem. If the printer supports LPD or
IPP, you probably need to enter a device queue name
in Printer Setup. (No queue name for HP Jetdirect
protocol) L1, P1, LPT1, and print are common queue names
I have set up so that Printer Name is 192.168.0.200. This automatically selected Lexmark Optra T. Also the queue name appeared as 192_168_0200-1. Host name was blank and Driver Version 10.4 and PPD File Version is 10.4.3.3.0. I tried to print the Print box showed Preparing . . then Processing Page 1 and dissapeared in the normal manner. I opened the Printer Monitor (in the dock) and it showed the job in the queue as it should and the Status showed: printing. The blue bar scrolls and the message Connected to 192.168.0.200 comes up. The printer shows no sign of receiving the file. I have done this numerous times. I have also keyed in the computer name in the location and still no go - just the same outcome. The computer name is ian-brownlees-computer.local.
Look in the printer manual or google for it.
Unfortunately I don't have a manual but have been trying to locate one.
Any further clues??

5300 RAM showing up as 3200 in Quad, any experience with this problem?

Hello, just received a 2 gig kit for my G5 Quad (2 - 1 gig sticks from Crucial). System Profiler shows it's speed at 3200, lower than the original 512 RAM which is 4200. Crucial says it will only reach 4200, but why is the new RAM showing up at 3200? Tried removing original RAM and only using the new, same speed displayed - 3200.
Has anyone had any experience with this oddity? Any idea if the RAM is not performing or the Mac is not giving accurate speed data?
Thanks, Steve

Memory identified as PC2600 in MDD
Symptom
Apple Hardware Test identifies the computer's memory as "PC2600" rather than "PC2700".
Products affected
* Power Mac G4 (Mirrored Drive Doors)
* Apple Hardware Test version 1.2.6
Solution
There is nothing wrong with your computer's memory. This issue is addressed in Apple Hardware Test 1.2.7. If you have version 1.2.6 and are experiencing this issue, contact AppleCare for a replacement disc.
Apple is aware of that. It first showed up in 10.3.0 and has been there ever since. The issue with the above DDR2 is I think different and unique.
With the MDD, Apple used Micron in the system I got, and I added Crucial. Both show up as '2600.'

Hi, I was wondering if anyone has any experience with the 750gb 7200rpm hitachi hard drive in a late 2008 MacbookPro

Hi everyone,
I find the speed and space in my macbook pro is not enough for me anymore. I was wondering if anyone has any experience with the Hitachi 750gb/7200rpm hard drive? I have a late 2008 Macbook Pro (15 inch, 2.93 ghz C2D, 4gb ram) running osx Lion and was wonder about compatibility with said drive.
Thanks,
Kevin

If its this one, your good to go:
