Description of problem: When using gnome-power-manager to suspend / hibernate a computer with the Nvidia or ATi (I havn't actually seen the ATi part as I don't own a ATi card, but I've heard the same thing happens) kernel module loaded, the screen will never wake up from the suspend or hibernate, forcing the user to unplug the system. This in turn can cause filesystem damage that can cause serious problems! (Same issue in FC4 and I had to reformat once because this heppened) Version-Release number of selected component (if applicable): Fedora Core 4 (with acpid) Fedora Core 5 (with gnome-power-manager-2.13-93) How reproducible: Always Steps to Reproduce: 1. Install the Nvidia kernel module (either from the nvidia site or Livna RPM) 2. Install gnome-power-manager 3. Suspend / Hiberate 4. Hit a key or move mouse to "wake up" the computer Actual results: the screen goes black, then a "no signal" message displayed is by the screen Expected results: Screen should "wake up" meaning an image should return instead of "no signal" Additional info: Although it works fine without the nvidia module, great work guys!!

Sounds like a kernel bug. >it works fine without the nvidia module Then it's not a gnome-power-manager bug, please report to nvidia.
I've done more investigation into this, and it's a combo of problems. Firstly, it seems that I cannot suspent without using nVidia's AGP, and not AGPGART - I have to boot with agp=off for it to work (I have a AGP 4x card) Also, in /etcpm/functions-whatever, one must comment the line 'vbetool post'. After that, I was able to get the screen to resume. Stewart
Sorry, I meant /etc/pm/functions-whatever. In my case, I had to edit functions-nvidia, but for others I'm guessing it would require the respective file. Stewart
