Ogre 3D 'glGetString' Problem, May Be Driver Issue

Hello!
I'm relatively new to Arch Linux, all I did till now was install it and get X running with the 'awesome' window manager. I must say, I like it, especially pacman, AUR and ABS.
I'm a hobbyist programmer and I generally write graphics applications (games) with Ogre 3D. I decided to get Ogre 3D and build it. I got the latest SVN HEAD, and built it, it built fine. However, when I run a sample, I get the following error (which occurs right when it tries to create the GLX subsystem):-
OgreGLSupport.cpp:57: virtual void Ogre::GLSupport::initialiseExtensions: Assertion `pcVer && "Problems getting GL version string using glGetString"' failed
I've run Ogre 3D applications both on Windows and Ubuntu on this very same laptop, so I don't think its a hardware issue. It may be a driver issue though. I have 'xf86-video-intel' installed, and hotplugging turned off with "AutoAddDevices" "False" in xorg.conf. 'lspci | grep VGA' gives:-
Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)
It is possible that it's an Ogre specific issue, but I still thought I'd mention it here because it could also have to do with drivers and other configuration stuff.
To check whether glGetString() works, I took the program from the second NeHe tutorial and modified it to spit out glGetString results, and it says "Vendor: Mesa Project, Renderer: Software Rasterizer, Version: 2.1 Mesa 7.2".
I've also run some other graphics applications (the Bullet physics engine (which I just built today) demos), and they run much slower than how they did on Windows and Ubuntu.
Any ideas what the problem is and how to fix it?
Thanks for your help!

Humnn... I don't know. How I "solved" it today: downgrade xorg-server to 1.5.3, catalyst to 9.4 and kernel to 2.6.28. Now I have my game working again. I think it was only a problem with the driver... I'll try to upgrade asap.

Serious Audio Problems/External Hard Drive Issues?

I have a hard drive that I imported about 40 hours of footage into using iMovie HD a few years ago. I am now trying to import all of that footage into a new external hard drive using iMovie '09. I set it up and imported it correctly, but for some reason the audio has all disappeared. The audio is still there in Quicktime, but it didn't transfer over into iMovie. Is there anything I can do to solve this?
The way I first tried to solve it was by dragging the Quicktime clips to my desktop, then importing them back into iMovie. It worked for a little while, but for some reason at about the 20 hour mark it decided to drop all the audio out of those clips as well.
Then, I decided I would get wise. I said, "Screw it. I'm just going to re-import the whole 40 hours from the original mini DV tapes." So I set my camera up and started importing them. Everything was going swimmingly until about the 20 hour point again. And that's when the audio decided to drop out on me all over again. I was HIGHLY frustrated, and am still at a loss on what to do.
Does anyone please have any solutions for me? I would desperately like to get this footage imported into iMovie '09.
Thank you,
Aaron
P.S. I don't know if it means anything, but a couple of the clips that were imported have green and purple pixelated lines running down them. Could there be an issue with some of my mini DV tapes as well that's causing the audio drop out?

Hi, try the following:
select the external HD in the finder and press >cmd-i<
unlock and make sure you are the owner
now choose >Apply to enclosed items……<

Toshiba Satellite a505-6005 hard drive issue and questions regarding options I may have

Issue: start up computer and windows does not start. It eventually goes to a startup repair screen and eventually says "resolving disk errors...", and that's if it even gets to that screen. Unfortunately I never made a recovery disk or system image discs (I know that was not smart). I did however kept my files backed up so that was good.
Steps I took: Took it to Best Buy and the tech advised me that the Black Tie 2 year protection had expired on Jan 30th 2012, and so it could not be repaired for free. I asked the tech there how much it would cost to fix and they had advised me that it was most likely a hard drive issue and that it would cost nearly $400 to replace/fix it. So I decided to buy a new Asus K53E-BBR14 laptop since it was not much more. When I got home and loaded everything up and got the computer to how I want, I went ahead and made a recovery disc and system image disc's. I tried using the recovery disc that I had made with my Asus in the Toshiba laptop and boot it from the dvd drive and it did not get anywhere. So I ASSUME that it really is a hard drive error because the RAM worked just fine in my new laptop and "repairing disk errors.." means something is wrong with the hard drive:
Now that you know the background of what has happened my questions are as followed:
1. Can I buy a new hard drive for the Toshiba and use the recovery and system image disc's i created on the new hard drive that i install in the toshiba? and just removed the bloatware from Asus (or does that not even get added to the disc's I created)?
2. If so, will it prompt me to enter the Windows 7 product key? and therefore using the product key located on the bottom of the toshiba?
3. What other steps could I take to make this toshiba laptop salvageable? This way i can turn around and sell it.
Thanks,
Russell States

Also,
I noticed that i can purchase (well pay the shipping anyways) recovery media from Toshiba. Can I use that on a new hard drive installed in the toshiba?
BTW ran the Windows Memory Diagnostics Tool and no problems were found with the memory. and i do not care about the old hard drive as I have MY files backed up. I just want to try to get this toshiba laptop back to being "like new".
Thanks,
Russell

On windows 8 and itunes I have importing problems the DVD is only reading the music cd from 1.5x to 4.0x for 95% of the time, it does hit speeds of 30x for the other 5% of the time. Is it a driver issue with the DVD or is it a windows 8 issue?

No. You have no alternative but to plug it into a computer running iTunes and restore it.

Itunes/external hard drive issue - i cant find the answer anywhere

okay so here it is:
i am currently using an imac g5 (v. 10.4.8) and i just got a g-drive to store my music onto. i am using a 400 firewire cable and i have tried a few different methods to copy my music files to the drive (methods are listed here) but every time i transfer any song to the drive, it gives me this:
"the finder cannot complete the operation because some data in "file name" could not be read or written. (error code -36)."
i have looked through numerous forums about this problem and some have suggested to check the firewire connection but i doubt it's the connection because other files such as microsoft word documents or pictures can easily be transferred onto the drive without any problems.
my itunes library is comprised of mp3/m4a files.. some of which have been downloaded, others taken directly from my cds. i tried to see if this problem was occuring with my downloaded files (assuming some of them may be corrupted) but it's not the case because the error shows up with EVERY song I try to transfer onto the drive.
the problem MAY have something to do with the fact that... a long time ago, i tried to get rid of all my album artwork and i was looking through forums, and one of the solutions was to convert my files to "aac" (which can be done in the itunes preferences menu). however, i've tried converting some songs back to mp3 formats and transferring them again and it still doesn't work. also, one time i converted the id3 tags of the songs, but i dont think that has anything to do with it
this is the given information for one of my itunes songs if it's of any help:
i think i've tried just about everything, please help me! thank you
Mac OS X (10.4.8)

Some things to check:
What format is the drive? Is it formatted for OS X or for Windows? If windows is it FAT 32? Each of these have different naming conventions, different read and write capabilities. If your drive is only for use with your Mac, reformat it for Mac OS Journalled using disk utility.
This may also be a file permissions issue. As as we're not dealing with System Files here, Disk Utility is of no help.Try setting the permissions on the folder using BatchMod from

Windows 8.1 BSoD & driver issue

Hello,
I was hoping someone could help me out here. Let me describe the issue. For quite a while I was using Windows 8.1 fine and did not have any problems, however I recently burned my PSU somehow and then the problems started. Which I somewhy find odd, cause the
BSoD's are related to a driver issue(?). The driver which seems to cause the problem, is
Intel(R) Engine Management Interface.
"This device cannot start. (Code 10)
A device which does not exist was specified"
Event Viewer displays the following error:
"Intel(R) Engine Management Interface driver has failed to perform a handshake with the Firmware."
Since it says "A device which does not exist was specified.", I assume I don't need this driver at all, so I tried disabling it and uninstalling, but it keeps coming back every time I restart my PC. I even tried looking for a newer driver, but couldn't
find anything. The newest driver is for Windows 7 x64/x86. I found out you could possibly disable it in bios, but I couldn't find the option to do so in my bios. I went thru every option 1 by 1, just to make sure, I wouldn't miss it.
Here's my PC:
Motherboard: Gigabyte GA-H55M-S2 (F4 BIOS)
CPU: Intel i3 540 @ 3.07GHz (Overclocked to 4,03GHz)
Cooler: Cooler Master Hyper 212 EVO
GPU: NVIDIA GeForce GTX 660 (GV-N660OC-2GD)
RAM: 2 x Kingston 4GB 1333MHz DDR3
HDD: Western Digital 500GB
At the very moment, I have installed a fresh copy of Windows 8.1 Professional x64 and the problem still seems to exist. I have tried and googled for everything I can think off, now I'm just stuck at this problem.
I hope someone can help me out here, or at the very least, guide me in the right direction.

W510 problems with Nvidia driver recovery under Windows 7 (64 bit)?

Lenovo W510, Nvidia Qudardo FX 880M video, FHD:
What I'm seeing on occasion is a Windows 7 (64-bit) recovery, screen blanks out, goes 2-3 seconds, then recovers, things go back to normal, but a message displays saying that an error was detected in the video driver, and it has recovered. The new Firefox (4.0.1) seems to be one of the things that may be a contribution, hard to tell. Per System Update at least, I'm current on the Lenovo downloads. SIW shows the driver level as 8.17.12.5738 (2010-06-27). Nvidia web-site shows their current driver level on the wen-site as 270.61 (2011-04-18), which is a considerably newer date at least. So two questions:
Has anyone else seen Driver/Recovery issues on Win 7 (64)
Has anyone directly run the Nvidia video drivers and had them run OK?
Seems like it would be nice for Lenovo to update their drivers, if indeed this is a driver issue, they appear back-level.

I used to have this problem with my W510 running Windows 7 Enterprise 64-bit, especially Firefox 4 crashing the Nvidia display driver almost constantly. I googled and found that this is a known problem between older Nvidia driver and Firefox 4. Later on I downloaded the latest version of Nvidia driver from Lenovo website (it was not posted on the System Update server yet but was available on the regular download site). I clean-installed it (i.e., removing all files and settings created by the old driver) and I haven't experienced the problem since then.

Can't install CS3 Upgrade on NEW iMac 24". An Imac DVD drive issue?

My CS3 Design Premium Upgrade CD fails to install Photoshop on my BRAND NEW iMac yet it is able to install everything else on the CS3 disc. I just bought this iMac yesterday and CS2/CS3 Upgrade are the FIRST things I installed (besides updates) when I turned it on. I'm still using 10.4.10.
I searched through the Adobe forums and the internet as to how others with the same issue have dealt with the problem, but it seems the most common reason is that people had installed Photoshop CS3 beta previously as well as older Flash/Acrobat plug-ins conflicting with the installation process. Further, these causes seem to be effecting Windows users.
So a few hours ago I tried to COPY the upgrade CD contents to my hard disk, I get the message:
"The Finder cannot complete the operation because some data in 'AdobePhotoshop 10en_US.dmg' could not be read or written. (Error code -36)."
This procedure of copying to the disk (and the resulting error message) is SPECIFICALLY addressed in the Adobe support pages TechNotes:
http://kb.adobe.com/selfservice/viewContent.do?externalId=kb401429&sliceId=2
The page says that it may be a drive issue that is causing the problem. Of the 7 possible solutions given on the page, I've narrowed it down to only 1 option left (but I can't try it since I don't have another Mac!):
"*Solution 4*: Copy the software to the hard drive of a different computer.
*If the software copies successfully, the model of DVD drive on your original computer might not be able to read the DVD. Contact the DVD drive or computer manufacturer for any updates that might be available.*"
But what's funny (or annoying rather) is, I had a 20" Alum 2.4 iMac earlier this year (returned because of screen problem), and the CS3 upgrade installed without any problems on it!..??? And according to the iMac specs, the 20" and 24" models both have the same DVD drive make right?
Any ideas??? Are there other 24" iMac users who are experiencing similar problems? If not, then I guess I may have to return yet another iMac...which I'm reluctant to do since this screen is PERFECT! I'm scared to get another iMac with the dreaded screen gradient issue.

I just solved the problem.
I tried copying the DVD files to the hard disk about 7-8 more times. The last try SUCCESSFULLY copied to the disk and I was able to install Photoshop CS3.
Yay.

Permissions Issue, Colour Wheel, Hard Drive Issue??

Hi!
I have had issues with my mid 2009 MBP recently and I'm wondering what the best way to fix them would be.
First off, I have some major permissions issues with my accounts. I am using 3 different users regualrly on the same machine and needed to access files from the home folder so I changed them a long time ago, and am not sure how to fix that. I have repaired the permissions countless times in the disk utility and it seems like there's always loads more to do each time. When I varify the disk, it says its all okay.
Secondly, I have had the machine freeze on me several times while doing very little on it. This happened awhile ago, and thought that it was just the permisions thing and so I did that again, and it started working better, for awhile. It would go a few days or weeks before doing the same thing, sometimes not even getting past the apple logo on startup before freezing. This makes me think it may be a hard drive issue???????
This morning, I tried dozens of times to boot, with no success at all..... until about the 25th time when it miraculasly booted. I have run permissions repair a few more times and it seems to be working okay at the moment, but the problem seems to be happening more often over time.
To complicate matters, I am traveling at the moment and will not be home for several months. I purchased an external harddrive last night and was able to successfully back up my data.
Question 1: Is it the permissions that are causing these problems, or is it related to something else. The computer seems to work fine when its working, and then once in awhile, decides its not going to do anything.
Question 2: Would upgrading to Lion (currently running 10.6.8) fix the permissions issues or just carry them forward? I would like to consolidate the 3 users into one, if that would solve it. Does the migration utility preserve permissions or does it give you a brand new start?
Question 3: If neither solving the permissions or the OS upgrade would fix the problem and it does need a new harddrive, is it possible to buy one and install it myself? I do not have apple care left on this machine and am on a very tight budget. I am used to taking things apart and all that as part of my job and it seems simple enough. Where can you buy a replacement??
Hopefully someone out there will be able to help me out on this one.
Cheers!!!!

Disk Utility permissions are separate from User account permissions.
This link is how to fix them

Disk Utility will always show something to be needing repair, but that's ok

Verify Disk is good, that's a good thing.

Your data is backed up, hopefully not with TimeMachine alone, but if you did, then get another drive and backup data manually to that as well. If the TM drive gets messed up, it's a pain to get your data off of it.
Question 1: Is it the permissions that are causing these problems, or is it related to something else. The computer seems to work fine when its working, and then once in awhile, decides its not going to do anything.
Well you could call Apple for replacement 10.6.x disks, and just reinstall 10.6 and bundled programs, but this can kick out kext files out of the /System/Library/Extensions folder installed by some third party software.
This method fixes OS X, but doesn't touch your files or most programs.
Nor will this method fix your Users accounts if the issue is in there.
A creation of a new user, then deletion of the others, return files from backup (set permissions) will fix User folder issues if the above user permissions fix doesn't work.
(Of course you could wipe the drive from the 10.6 disk, but you have to install all software again)
Would upgrading to Lion (currently running 10.6.8) fix the permissions issues or just carry them forward?
No, you don't want to install Lion, it won't fix those issues in User folders, not only that Lion has it's own issues and doesn't work with a lot of older software etc. No use clusterfscking a already bad situtation when it's seems it's only localized to the User accounts.
I would like to consolidate the 3 users into one, if that would solve it.
Yes that could very nicely and tidy up things in the process.
What you do is transfer all files to one regular powered storage hard drive.
(Don't use/disconnect the TimeMachine drive for this as it preserves the users seperated and you don't want all those users back restoring with Migration Assistant)
Create the New User on the machine as Admin, log into it and delete all the other Users, transfer all your files back from the regular storage drive, changing all the permissions to yourself before placing them into their respective folders as they will have three different permissions.
Notes:
If you have a extensive iTunes playlists on one User (say #1), then create the new user with that same name (will require some work, create User 4, delete Users 1-3, reboot, create User 1, delete User 4) then transfer your iTunes folder to Music of that User 1 (same name as before). This will preserve the pathnames of your song locations and your playlists will be preserved.
(before you ask, no you can't combine playlists)
Also if you have photo's in iPhoto Library, you have to right click on it and "show package contents" inside is a folder called Originals, copy them out and import into the iPhoto of the User #1.
Does the migration utility preserve permissions or does it give you a brand new start?
Yes it preserves user permissions, no it doesn't give you a brand new start. Only a fresh install, creation of new users and then just transferring of files does that.
Nothing about TimeMachine or Migration Assistant gives one a "fresh start", it's if hosed, so is your restore.
If you want that sort of pristine protection, you need to clone your ideal boot partition/drive using Carbon Copy Cloner (free/donationware) occasionally as a hold the option key bootable drive, then you can erase and reverse clone the pristine saved clone.
One can also update the clone on occasion, this way keeping the clone pristine.
I maintain 3 clones time dated, even have my boot drive partitioned 50/50 and auto-cloned, this way I have two boot partitions on the road and two externals at home.
I never use TimeMachine, it's not bootable (well it is on 10.7.2 only to restore though)

System Crashes repeatedly - hard drive issue?

I've been using my G4 933MHz with 2 internal hard drives for quite some time. I started having issues with the system crashing, while the system drive made a binding or poer up/down sound repeatedly. The drives were stacked on top of one another, so I bought a new cable and separated the 2 drives so they are now side by side. I thought maybe it was happening because they were getting too hot or something. The system worked for a few weeks, but is now back to having the same problem.
I've run both the Apple Disk utility and Tech Tool Pro and neither really come up with any problems. The Apple disk utility used to have issues seeing the drives right after a crash. Now it either sees them and says no fix needed or it doesnt see either drive at all.
Tech Tool Pro used to see both drives and all tests ran successfully. Now, I pretty much get a hardware nor supprted message each time I run it. At first I thought my system drive was the problem, but now I'm not sure. The fact that neither drive shows up in the disk utility makes me wonder if there is not some bigger problem. Both drives work perfectly fine sometimes. If I boot up a few times, they eventually show up and everything works fine for about 10-15 minutes, but eventually it crashes again.
Has anyone encountered this problem before? Or have insight into what might be wrong and how I could fix it? Or are there any other tests I can run, besides the normal hard drive tests? I'd just hate to go spend the money on a new hard drive to find out that my drives are fine and it's the system itself that is the problem. Any help is greatly appreciated.
By the way, the second drive is almost identical to the drive that came with the computer. I bought it from a mac dealer and it is the same brand.
Thanks,
Wil

They're both on the same ide cable. It's been setup this way for quite some time. One drive is setup as a master, the other as a slave. Never had any problems for the past couple of years. Issue just started about a month ago. Don't recall anything that may have triggered it. Just one night when I was sitting there, the whole thing froze. Ever since then, it has been freezing sporatically. Now it's doing it about every 2 minutes from when I get it booted up...if I can even get it to boot. Most of the time it just sits on a grey screen, then goes to the blinking folder with the system face and question mark, then after about 20 seconds of that, it eventually boots into the system drive and freezes or boots to the cd. It's completely random from what I can tell, as to which happens.

ITunes for 64bit Windows 7 Driver/CD/DVD/Drive Issues-

Hi There
I am sure that there are many many users out there suffering the same frustration as me in regard to ITunes just not working properly with Windoews 7 (64Bit).
I have been trying to solve the mystery of "ITunes for Windows Registry Settings Warning When Opening Itunes.
I have tried all the recommended actions to correct this problem without any success and I do mean ALL.
Below is a screen shot of my registry, can anyone see anything wrong with it?
In the meantime (Last four months) I have stopped using ITunes and instead have used Digital 7, this will be my very last attempt to get ITunes working properly, failure will mean consigning ITunes to the same place as any other Software that does not do wshat it says on the can.
I hope someone can help.

That's good that it is in device manager, but what about in Computer with the rest of the drivers?
Also, are the drives listed in Computer and device manager or just device manager?
I want to verify if the symptoms are present for a particular software issue before looking at other issues. I really doubt it is a driver issue at this point. If it was, then I suspect the issue would be present from day one.
It could be that the lens has dust buildup preventing it from working properly. They do make CD cleaning kits that have a special CD designed to clean the laser as it passes over the lens. If you happen to have one of these, or access to one, I recommend trying this step to make sure it isn't as simple as dust buildup interfering with the laser.
It could also be hardware failure, but I would like to try a few other steps before coming to that conclusion.
It may be worth reviewing this document as it covers a lot of the most common issues behind DVD drive issues. Feel free to skip any steps you have already tried.
Let me know what happens.

T22 CD/DVD DRIVE ISSUES

Hi can anyone help me i have a T22 running win98 and my CD drive will not read programme discs it plays dvds and music cds with no issues but will not run any programme discs. As the file that i downloaded from this site requires it to be run from floppy in dos mode but also requires the cd to be docked into the laptop at the same time which causes issues as only one can be in the laptop at a time i have purchased a external floppy drive but this requires USB 2.0 where the T22 comes with USB 1.0. So there is my problem please can someone help me here before my brain melts and drips out of my ear because i have run out of ideas.

win98 wont reconise usb 2.0 due to some kind of legal matter. Every pcmi usb card i have found will not run on win98 as the drivers start on win 2000 or newer versions
Interesting. I have an Adaptec AUA1411 2-Port USB 2.0 & 1-Port FireWire PCMCIA Card that I use with my A21p under WinXP Pro. Note that Adaptec provides USB 1.1, USB 2.0 and FireWire drivers for Win98SE as well as newer OSs. I bought this card several years ago. Unfortunately Google doesn't show anyone selling these today, however, you might luck out on eBay.
ISTR that Win98SE added some USB support to Win98, perhaps for USB 2.0. That may be the issue you're experiencing. Have you considered an upgrade to Win98SE? Have you explored Microsoft's support website for a patch to Win98 to support USB 2.0?
