Under Tiger 10.4 Brightness Adjustment Doesn't Work, Powerbook 17"

After trying Leopard, I decided to go back to Tiger. After installing 10.4 on my Powerbook G4 17" 1.67ghz the brightness adjustment in the system preferences and the F1 F2 keys do not work. Brightness adjustment is not available even after running all the updates through 10.4.11. If I return to Leopard, the brightness adjustment works again. Any one have any ideas on how to fix it in 10.4? [I don't have the original restore disks]. Thanks.

Not certain, but PRAM or NVRAM resets might do it...

Auto brightness still doesn't work after update my ipad 3 on ios 6.1

i actually can see the slider moves right and left when i temporary cover the sensor with a finger BUT when i place ipad under really bright light (the slider moves to the right completely) and then to the dark place it DOESN'T move to the left. i've just let it stay in a dark room for 5 minutes - NOTHING.
What the **** when apple going to fix that?

I have the exact same problem. Just did the 6.1 update from 6.0.1 and still no fix (iPad 3).
Once the back light brightness hits it's set value acording to the measured amount of light hitting the sensor, the screen brightness locks and stays on that level. You can verify it for yourself with a flashlight. The screen never goes completely dark either. It's super annoying. Set and forget? Auto brightness just doesn't work at all. Auto distraction at it's finest.

[Solved]Brightness control doesn`t work anymore

Hi!
I`ve made my 3rd update of Arch since installation, and... where previous two succeeded, the third one failed. It messed up my system
The problem is, i cannot change brightness any more through my function keys (and since i`m using Openbox as my DE, i cannot change it at all ). The brightness now is so low that i can barely see what i am typing. And it is not only in my Arch, it also messed up Windows and everything else: grub, bootup screen where i can select bios properties - everything. I ran xev and now i see that FN+Right/Left are not detected anymore as brightness keys. It says:
FocusOut event, serial 32, synthetic NO, window 0x3200001,
mode NotifyGrab, detail NotifyAncestor
FocusIn event, serial 32, synthetic NO, window 0x3200001,
mode NotifyUngrab, detail NotifyAncestor
KeymapNotify event, serial 32, synthetic NO, window 0x0,
keys: 2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
However, FN + Win + Right/Left are now detected as brightness control function keys
KeyRelease event, serial 35, synthetic NO, window 0x3200001,
root 0x13c, subw 0x0, time 521221, (348,-43), root:(1219,884),
state 0x40, keycode 233 (keysym 0x1008ff02, XF86MonBrightnessUp), same_screen YES,
XLookupString gives 0 bytes:
XFilterEvent returns: False
But pressing them doesn`t work either. I thought that it was xfce4-power-manager problem, but changing to gnome-power-manager didn`t help either.During the update pacman also upgraded kernel to latest version.
Any ideas?
P.S. My notebook is Acer Aspire 7720g with Nvidia 8600M GT. I tried solutions from this topic: http://bbs.archlinux.org/viewtopic.php?id=73889 but none worked for me... The problem is that the system is completely unusable at this point, since i barely see anything on the monitor, and that sucks

I can't see what you did in Arch affecting your windows installation at all. If you try to boot into windows and increase the brightness (since most laptops store the brightness level of the laptop as it was set, on battery, at least my 2 laptops do), does the new brightness level "stick" for all things? If so, the only issue you have is to re-map the function keys properly, and to configure a script or something to increase/decrease lcd brightness. You can make a simple script that echoes a value into your /proc/acpi/video/LCD/brightness file (the file path will vary, so it may be under UVGA or so). If, however, it doesn't increase again, it may very well be a hardware issue, and not a software (since, as I said above, it's highly unlikely that an Arch update has affected Windows in any way).

Tiger to Panther ok, reverse doesn't work

Hi, I can do a video chat perfectly when I initiate it from my Tiger PB (last version) to a Panther eMac (last version), but it doesn't work when the other party tries to initiate it with me. I get the invitation, I accept and then wait and wait and ... nothing is happening. Any idea?

Re-install Tiger, Software Update, now Airport doesn't work

So, I just replaced the hard drive on my Dual USB iBook G3. I completed the installation, and everything was working great. Airport was showing my home network (unsecured, iknow) and I was able to connect to Software Update via the Airport.
First major download was the 10.4.8 combined update for PPC - after downloading it and restarting I lost Airport connectivity. Can't find my newtork, can't manually input IP address, etc.
Next, plugged into Ethernet and downloaded Airport (4.2 ?) and still nothing.
What's the deal? Airport was working before the updates, and now nothing. Other laptops at home are working wirelessly just fine, so it's not my ISP, connection, or router.
Help!

Hi sockdaddy, welcome to Apple Discussions!
Click here to be taken to the Airport Troubleshooting kBase document.
It could be that you need a firmware update following the 10.4.8 update. Follow the steps in the above link, and post back with your results.
Another thing to try is the Mac OS Software update. Click on the Apple logo at the top left of screen while connected to the 'net, choose 'Software Update' and let the computer do the rest.
If all else fails, remove and re-seat the Airport card by following these instructions.
Let us know how you go.

Windows 8 Pro Upgrade Problems (Switchable Graphics, Screen Brightness Adjustment, etc.)

Hi guys! I hope you can help me with this.
My laptop is a Lenovo U400 bought last April. I upgraded it yesterday to Windows 8 Pro.
The Upgrade Assistant detected incompatibilities on the following softwares (I'll be mentioning only those I had problems with after the update.)
-AMD Catalyst Install Manager
-Catalyst Control Center
-Lenovo Energy Management
-Cypress Trackpad
After the update, the following problems occurred
-Windows kept prompting me about the incompatibility of Catalyst Control Center and Lenovo Energy Management
-When I check the Device Manager -->Display Adapters, My AMD Radeon HD 6470M was changed to HD 7400M and has an exclamation point on it indicating a problem. When check Properties it says, "Windows has stopped this device because it has reported problems. (Code 43)"
-I can't manage switchable graphics because the AMD Radeon driver has been stopped by the OS and Catalyst Control Center doesn't work. It says, "Catalyst Control Center cannot be started. There are currently no settings that can be configured using Catalyst Control Center."
-My touchpad works but does not support multitouch functions.
-Screen brightness adjustment stopped working both on hotkeys and Power Options.
I tried the following actions to fix the problems:
-Downloaded the new softwares from Lenovo Support but the Catalyst Control Center and Cypress Trackpad still doesn't work. I also tried installing driver software from the AMD site but it still didn't work. [FAILED]
-I tried to use the Cypress Trackpad software for U300s/e and it fixed the problem with the touchpad [FIXED]
-Installed the Energy Management software for Windows 8 but when I click the 'Optimized Battery Health' button, it keeps reverting back to 'Maximum Battery Life'. [PARTIALLY FIXED]
-Resorted to 3rd party software to fix the Switchable Graphics (Catalyst 12.11 Beta from leshcatlabs.net) and it fixed the switchable graphics problem as well as the Catalyst Control Center problem. This is temporary until a working solution or update is available. [TEMPORARILY FIXED]
-All actions trying to fix the Screen brightness adjustment didn't work. [FAILED]
Please do help me on this. Thanks in advance!!!

Yes I own U400 too and I'm using it now. To many forums been read, can't remember which one. Basically, u have to clean AMD and Intel drivers that come along with Win 8. Why? Because the Win8 driver database will lead the device ID "DEV_6760" (if you looking at display adapter device properties) to HD 7400 series instead of HD 6470M, again why? At the bigining only the HD 7400 series already "certified" by Microsoft, while the 6470M out of somewhere. Current CCC (or else) + 6470 drivers, contain also driver for 7400 series in same packages (at least until now, hopefully near future they will release an update). So you can gues where the windows will lead to? Yes 7400 series (certified one). This will explain also why the Energy Management didn't work to= "missing identifier" or we can say "hardware not match".
You have to find a "fix" driver which contain only HD 6470M and install it manually trhu "Have Disk" option, after you claan all AMD and Intel driver. If you success, then install the CCC from Lenovo Support and from ATI ( I use 12.11 Beta8 Net4 CCC - this is a must), but remember to unchek the AMD Display driver when you install both CCC, and leave the rest checked including Intel Component. Then you can download install anything you want =).
Leschat's driver did't work on my and "harm" the system. Believe it or not, I found the AMD 6470M standalone driver on HP website. They call it "SoftPack", which actually contain CCC software.
It's quite tricky thing, that's why not everyone willing to try. But I think it's worth to try, as the risk is not too deep, just backup anything befor you do it. Cheer

Boot Camp doesn't work in Tiger

I just downloaded Boot Camp version 1.3 on my old Tiger MacBook Pro but it doesn't work. It says version is outdated. Is there newer versions and where can I download them? I tried to find 1.4, it seems like it doesn't exist.
Thanks for the help

Yeah, I know. I can't believe that about Apple. If Microsoft came out with an update for Windows that was that mediocre and charged $129 for it, you'd never hear the end of it.
You're right, it's called Leopard...not service pack 5. Sorry, coming from the Windows world, I'm used to updates like that being called service packs.

Photoshop CS4 Photomerge doesn't work under windows 8.1

Hello!
I have Photoshop CS4. Whereas it worked very well under Windows XP SP 3, I have a problem using it under Windows 8.1.
Photomerge doesn't work. As soon as I click on it, It shuts down Photoshop.
I have a trial version of Photoshop CS 5 and photomerge works well in this version.
I tried to solve the problem through Windows but it didn't work.
Please help.
Thank you.

Hi @inetdude
Since there is no full feature software and driver for 8 or 8.1, I am not sure what else to suggest other than for you to reach out to Microsoft. The driver you are using is an in-OS driver, perhaps they can help you.

PSPaletteMenu category doesn't work for automation plugins

Hello,
I would like to have a menu item under Photoshop "Window" menu for my automation plugin.
There is a notice in the PIPL.r file that goes with SDK:
// Use PSPaletteMenu category to add a menu item on the Window (i.e., palette) menu.
// This is currently only enabled for automation plugins.
PSPaletteMenu ="**Palette**";
However when write my PiPL res like in example below
resource 'PiPL' (ListenerResourceID, plugInName " PiPL", purgeable)
Kind { Actions },
Name { plugInName "..." },
Category { "**Palette**" }, // or Category { PSPaletteMenu }
Version { (latestActionsPlugInVersion << 16) | latestActionsPlugInSubVersion },
menu is not shown under Window menu :(
Want to note that if I specify Category { PSHelpMenu } it works correctly and menu item is shown under Help menu. PSPaletteMenu also doesn't work for Listener plugin that ships with PS SDK.
Looks like plugin is not recognized as automation plugin, but I have correct info.plist props (on MacOS X version)
What should be done to have my plugin menu item under "Window" menu?
Regards,
Mac Developer

Hi Tom, thanks for your reply. Actually I'm not asking about floating palette (which I actually created and there is no issues observed). I just need my automation (!) plugin entry point to be called with kPSDoIt ("Do It") selector action after menu item is chosen under Window menu. (like it works in case PSHelpMenu)
In the PIPL.r file that goes with SDK it states that
// Use PSPaletteMenu category to add a menu item on the Window (i.e., palette) menu.
// This is currently only enabled for automation plugins.
PSPaletteMenu ="**Palette**";
Is it documentation issue?

Satellite P500-127: microphone or sound doesn't work properly using skype

Hi Toshiba team,
Recently bought a new notebook.
However the microphone or sound driver (connexant pebble high definition ) doesn't work properly when using skype. Also read about this matter in various forums such as the skype forum.
People encountered similar problems such as:
We can usually talk for a bit longer than 20 seconds, however the call will drop at a random time between 1 and 15 minutes. The strange part is that sometimes the quality of the call is good, but more than often my friend can only hear *half of what I am saying* while I usually do not have a problem hearing what has been said. The video will work so my friend can see me talking but can simply not really hear what I am saying.
Before the drop the call will usually freeze for a couple of seconds and then skype sometimes crashes. We have tried talking together without the video, however the problem remains.
I also found a suggestion by the toshiba service, just to simply increase the volume under control panel etc, but it doesn't work either..
Can you please help me on this one?
Cannot use skype at all as it just to annoying for everyone I talk to.. Quality is just to poor!!
Many many thanks

Hi
Every day I use Skype with the internal webcam, microphone and speakers but I didnt have any problems as yet.
In your case I would try updating the drivers. Therefore download the latest sound and webcam driver (microphone is a part of webcam). Both you can get here:
http://eu.computers.toshiba-europe.com > Support & Downloads > Download Drivers
If your friend cant hear you, check also the settings for internal microphone. I have activated microphone boost in Windows sound settings so I could improve the microphone quality.
By the way: Do you use the latest version of Skype? With older Skype version I had also some problems on Windows 7. As far as I know only newest version is fully Windows 7 compatible.

Why does Airtunes Drop Frequnetly under Tiger?

After having sifted through the last week's worth of posts to this forum, I find that I'm having a problem that many others are also having, and that it has yet to be solved. I'm posting yet another thread on this topic, hoping that Apple will take notice.
Since upgrading to Tiger, I've had a bad experience with Airtunes frequently dropping out. Sometimes it resumes playing after a few seconds, sometimes it doesn't. Sometimes disconnecting from my wireless network and then reconnecting fixes the problem, sometimes it doesn't. As far as I know, everything is up to date:
Mac OS X 10.4.7
iTunes 6.0.5 (20)
Apple Base Station v6.3 (that's the firmware)
Software update gives me weekly updates too, so my Airport software should be current (how does one find the version number for this?). This problem also ocured under firmware 6.1. A hard reset of the Airport Express did not fix the problem either.
The strangest symptom that I experience is when Airtunes drops out and I try to deselect my speakers in iTunes. It just hangs and I get the dreaded spinning beach ball. After 2 or 3 minutes it finally deselects. Sometimes if I reselect the speakers, Airtunes resumes working. But other times it just seems dead.
While all of this is going on, my internet connection through the APExpress is still ok.
Airtunes worked flawlessly for me under Panther. So I'm fairly sure that the problem arose when I switched to Tiger.
Anyone know how to solve this problem (other than downgrading to Panther)?

Okay, I've read the posts in this thread and think I might be able to contribute.
My set up is an Airport Extreme Base, with two Express's. I'm new to all this WiFi stuff, and have built this system adding each component over the past two years. So, frequent droping out has also been a problem with my setup. Yet (fingers crossed) i think I got things working pretty well with, ahem, (almost) no drop outs in days.
1. First suggestion is this link.
http://www.macgeekery.com/hacks/hardware/optimizingairportconnectivity
It basically talks about channel switching the Extreme Base Station and how to find out who else might be using that channel. With hints for advanced software from Apple (and where to get it) that I did not have, that helped me monitor signal strength and other neet learning tools.
2. I purchased airfoil recently (great software IMHO), and in the troubleshootong section it talked about how any 802.11b hardware (like my 867 Tibook) automatically down throtles your network from a potential 54 mbps to 11mbps. Now I'm not real versed on what sort of thru put you need to stream this music stuff, but 11mbps probably is not enough for two consecutive streams (w/o constantly dropping out). I have not heard of this potential problem disscussed ANYWHERE else.
3. One of my signals has to travel down a long hallway to reach the Express & speakers, 50 feet, and the signal would always stop when (it seemed as though) I would walk down it. My body seemingly disrupting the signal.
This has seemed to dimminish after my last (#4)suggestion. A house full of people would (i think) kill any signal(s) no matter how strong the signals are.
4. Upon messing around with the settings in the Airport Administrator Utility,
i accidentally had it set to 25% of its potential Transmitter power (under Airport-->Airport Network -->Wireless Options. That fixed alot, boy I felt stupid.
So, these may be things worth looking into. In addition, I have a couple of ?'s.
1. what is the multicast rate? it's under Airport-->Airport Network -->Wireless Options also. what do ya'all have it set at?
2. Would WDS have a positive signal strength effect with an Extreme Base Station and 2 or more Express stations.
I have never run any WiFi under panther, but have had constant drop out issues under tiger until recently (who knows, maybe they'll return)
Goodluck all !!!!
