Public bug reported:
Binary package hint: xserver-xorg-driver-nv
I have noticed various reports referring to the non-free binary drivers
and suspend/resume. Of course, there is not much we can do about that.
This bug report refers solely to the free driver with Xorg. I don't use
non-free binary drivers.
Ubuntu Gutsy Tribe 3. Kernel 2.6.22-8-386
Chipset: integrated Nvidia 6100 GPU
Expected results:
After enabling S3/STR in BIOS, launch Ubuntu. System->Quit Suspend. Machine
should power down. On key combination within seconds restore to where I left
off.
Actual results:
After removing USB driver ( Bug #128322 ) (irrelevant to this bug but necessary
information to reproduce bug). System->Quit->Suspend. Machine enters suspend
mode. Hit key combination to resume. Machine appears to resume, but no display.
Try ctrl+alt+F1,2,3,4,5 etc. No display. Hit ctrl+alt+f1 then
ctrl+alt+del. Machine reboots. Machine clearly not catatonic.
Try suspend/resume again. hitting ctrl+alt+backspace appears X windows
re-starts. No display.
Log into machine via SSH over ethernet. Kill GDM. Restart GDM.
/var/log/Xorg.0.log is re-written. Still, nothing on screen.
As mentioned elsewhere, try editing /etc/default/acpi-support.
# Should we attempt to warm-boot the video hardware on resume?
POST_VIDEO=false
Made no improvement. Revert back to true.
Shut down system. Added S3 PCI graphics card. Re-configured xorg,
removed USB driver. Entered and resumed from suspend mode. All OK.
Shut down system. Added PCI Express Nvidia 6200 GPU disabling on-board
GPU. Entered & recovered from suspend mode. On surface, symptoms look
same as with 6100, but actually not. When recovering from suspend with
6100 GPU, machine completely freezes. Not possible to log in via SSH.
Need to pull power cord.
