10.5 sleep problem

For the record I'm having the same problem with my 17" FP 800 mhz imac. Put it to sleep and the monitor fades to white, try to wake it back up and the computer is on, clicking randomly results in some unhappy beeping noises eventually, but the screen stays black. Trying to sleep the monitor doesn't work at all.

I'll probably just downgrade back to 10.4 and give up hope, but you can be sure I'll be watching this thread closely. Fingers crossed.

Sounds wonderful, but although I have a Radeon 9600 Pro and the problems you describe (not waking up properly after sleep), I can't locate the ATI ROM Xtender file in any version of Tiger I have looked at. Specifically I have checked 10.4.9 PPC and 10.4.10 Intel, together with inside a PPC Combo 10.4.10 updater (using Pacifist) and inside a number of other updaters and I can't find this file anywhere. Where EXACTLY (location and Tiger version/architecture) is this file to be found?

TIA,

Nick

Me too 😉 am having a FP 800 MHz iMac.
I think it has a NVIDIA GeForce4 MX AGP card, so I'll probably compare what drivers are in Tiger and compare it to Leopard to see if the ATI trick mentioned earlier in this thread will work.

Hmm - no sings of any NVIDIA.kext's at least by name (Tiger as well as Leopard!) - what KEXT does the NVIDIA card use???

not a big difference (it's probably best in Leopard…)

Great, this solved my problems.

thank you!

FYI: The topic of the iMac G4 800 sleep problem is also being discussed at http://forum.insanelymac.com/index.php?showtopic=69135&pid=492042&st=0&#entry492 042

Has this been fixed with the 10.5.1 update?

I'd like to be able to put Leopard back on my iMac G4.

I just tried it on my 800 MHz iMac G4. Upgrade install of 10.5 over 10.4.11, then applied 10.5.1.

Same sleeping problem with 10.5. Graphics corruption galore when waking from sleep. Also, when the display goes to sleep (machine still on), it doesn't turn off. Instead, whatever was on the screen stays on the screen, and the brightness goes to full.

Let's hope for 10.5.2. 🙂

I was having a similar sleep problem and deleted the power management plist, then rebooted.

This plist is located in /library/preferences/systemconfiguration. It is called com.apple.PowerManagement.plist

Hope this helps.

Russa,

Did you try this on an 800 mhz imac G4?

No, I did this on my MBP 2.4GHz. However, my iMac G4 does not exhibit any sleep problem.

Worked for me too, thank you VERY much.

Who knows what the possibilities are for upgrading the video card in the iMac G4/800? There has to be some overlap in the list of compatible video cards between the iMac and Leopard. I'd be willing to give it a try, but I know squat about video cards.

I've got a workaround, but it disables Quartz Extreme.

Back up all of the GeForce* and NVDA* files in /System/Library/Extensions. I stuck them in a folder called /System/Library/Extensions/geforce-10.5.1 to keep a backup. Then, remove them and replace them with their Tiger equivalents. Make sure that the ownership of the files is correct:

bash$ sudo chown -Rh root:wheel GeForce* NVDA*
bash$ sudo chmod -R a rX,uw,go-w GeForce* NVDA*

The 10.5.1 set of files includes:

GeForce.kext
GeForce2MXGLDriver.bundle
GeForce3GLDriver.bundle
GeForce8xxxGLDriver.bundle
GeForceFXGLDriver.bundle
GeForceGA.plugin
GeForceVADriver.bundle
NVDANV10Hal.kext
NVDANV20Hal.kext
NVDANV30Hal.kext
NVDANV40Hal.kext
NVDANV50Hal.kext
NVDAResman.kext

10.4.10 doesn't include GeForce8xxxGLDriver.bundle or NVDANV50Hal.kext.

The only bundles relevant to the GeForce4 MX card are GeForce.kext, GeForce2MXGLDriver.bundle, NVDANV10Hal.kext, and NVDAResman.kext. You need to take them as a group, or you'll wind up with a system that won't load any graphics drivers or won't boot at all. I take all of the rest of the files to keep things in sync.

If you've loaded the Tiger drivers, you should see something like this:

bash$ kextstat | grep -E 'GeForce|NVDA'
68 2 0x2f293000 0x23a000 0x239000 com.apple.NVDAResman (4.5.6) <67 66 17 12 6 5 4 2>
87 0 0x2616e000 0x5d000 0x5c000 com.apple.GeForce (4.5.6) <68 67 66 17 12 6 5 4 2>

This resolves the "display sleep blanks display but doesn't turn it off" problem for me. I never put the affected computer to sleep, but I tested that too, and am able to make it sleep fully, wake it up, and resume using it without any video artifacts.

Unfortunately, Quartz Extreme winds up disabled with this workaround. That may run interference for some applications.
