NVIDIA Card Fails to Suspend

Hi bedna,

thanks for the links.

  • First I tried disabling kernal-module nvidiafb, didn’t work.
  • Then I checked if there are any i2c devices that trigger the wakeup ($ ls /sys/bus/i2c/devices/*/power/wakeup), there were none.
  • After that I followed your second link to also preserve the video-memory when suspending. Doing that lead to the journal-entry below. However, since the issue still persisted I disabled that feature again.
Aug 17 13:00:06 machwx9 kernel: NVRM: GPU 0000:01:00.0: PreserveVideoMemoryAllocations module parameter is set. System Power Management attempted without driver procfs suspend interface. Please refer to the 'Configuring Power Management Support' section in the driver README.
  • Last thing I tried was to change the suspend-method from deep to s2idle, but sadly agiain without any change.

I’ll investigate a bit further this afternoon.

Cheers
Karsten
