Currently Being ModeratedOct 31, 2007 7:17 AM (in response to plasticbagirl)I have the same problem described by others. My iMac G4 sleeps fine but when you wake it the screen comes on with a mottled green pattern on that slowly fades to solid white. I can hear the hard drive doing stuff in the background, and Time Machine kicked in when I woke it up this morning but every time the machine is unusable because I can't see anything.
NB for those yanking the plug out of the back of their iMac to get it to power off, STOP DOING IT, it's not good for the hard disk. You can force any Mac to shutdown by holding the POWER button (on the back-left on the G4 iMac) for 4-5secs. This does a safe power off, allowing hard disk operations to stop before the power cuts out.
I've also had a similar issue since I got the Mac Pro, but I thought it was just my Samsung LCD screen on that. When the monitor goes in to DPMS sleep mode, I have to turn it off, wake the Mac Pro, then turn it back on because otherwise the screen fills with garbage, but THAT machine sleeps and wakes fine with no video issues. DPMS monitor sleep works flawlessly in Windows XP and Windows Vista too so I guess it's OS X's NVIDIA drivers, I was hoping 10.5 might have a fix for it but it appears not.
In both cases I suspect the video drivers are at fault.

Currently Being ModeratedOct 31, 2007 11:14 AM (in response to plasticbagirl)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.17" FP imac, Mac OS X (10.5)
Currently Being ModeratedOct 31, 2007 4:04 PM (in response to Richard Boileau)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?

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.iMac 24" and a lot more, Mac OS X (10.4.9)

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 042iMac G4 800, Mac OS X (10.5)
Currently Being ModeratedNov 16, 2007 4:59 AM (in response to Shamus McCormick)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.MBP 17" 2 GB RAM 120 GB HD, Mac OS X (10.5)
Currently Being ModeratedNov 16, 2007 7:25 AM (in response to plasticbagirl)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

Currently Being ModeratedNov 30, 2007 5:20 PM (in response to Thomas von Eyben)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.MBP, MB, PMac G5, a few Linuxes, Mac OS X (10.5.1)
