10.5 sleep problem

Do you have a backup?

You might consider cloning back over, and reapplying the update. The other option is an Archive and Install of Leopard. First choice is easier, and less chance of "ripping" third party contextual menus, Pref Panes, and drivers, out.

My machine has trouble sleeping, it starts to enter sleep mode, but the fans keep running. It will not wake from sleep and I have to cycle the power.

On my G5 quad the fans also run at full tilt if the processor peformance is set to hightest, switching to Automatic makes the fans run down.

Same problem. Unable to wake from sleep mode other than unplugging and replugging. Did the "permissions" verification etc without success. I also have a WD HD attached via USB.

My problems seem to have been solved by a re-install of the ATI drivers for my X1900 G5 edition.

I've got the same problem. I installed 10.5 on my 800MHz G4 iMac through target disk mode from another G4. When it goes to sleep the screen goes to blank or colorful stripes. Only hard restart will bring it back.

Since upgrading, every time my machine wakes from sleep (I can wake it with the mouse) it will, once fully awake, disable whatever USB port my mouse is plugged into. It's an old RF wireless MS mouse that DID have random outages such as this on Tiger, but only after the machine had been on for several weeks (multiple sleeps/wakes) and while the mouse was plugged into the keyboard's USB slot. Now, however, it is always plugged directly into the tower's USB and happens every time it wakes up. The light on the receiver that is plugged in will remain on as if it receiving power but will not work. Once I unplug and plug back in the light will not turn on and no device will work in that port until I restart. Chalk that up as another wake-from-sleep-issue.

Ati Radeon problems and solution...

There is a missing extension in System/Library/Extensions/AppleNDRV(folder).

For those who have Ati Radeon 9600 PC and Mac Edition (maybe for other card also), ATI ROM Xtender is missing in Leopard causing sleep and display problems. The AppleNDVR folder contain only two extensions (AtiDriver.bundle and ATIRuntimeDriver.bundle). You need ATI ROM Xtender from Tiger to have a correct display. Just put it in the folder and restart.

I was ready to go back to Tiger when i found this. I did one Archive and Install and one clean Install on two different drives and had display and sleep problems. I'm very happy now with Leopard !

Thanks! This solved both my sleep problem and my graphical glitches!

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.
