gnome-power-manager failes to wake screen after suspend with nvidia/ati modules loaded
Last modified: 2015-03-04 20:16:48 EST
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)
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
the screen goes black, then a "no signal" message displayed is by the screen
Screen should "wake up" meaning an image should return instead of "no signal"
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.
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.
