[BUG] /lib/udev/rules.d/80-nvidia-pm.rules disables rtd3 power control #106

Closed cemkaya-mpi closed 1 year ago

cemkaya-mpi commented 1 year ago

Describe the bug The file /lib/udev/rules.d/80-nvidia-pm.rules results in no rtd3 power control on my laptop with RTX3060 and Ryzen 6800H.

To Reproduce Steps to reproduce the behavior:

  1. Run sudo envycontrol -s hybrid --rtd3 3 --reset-sddm --verbose
  2. See that the GPU never powers off

Expected behavior The discrete GPU should power off when not used.

System Information:

Additional context After removing the file, rtd3 works again.

Interesting results, does it work without the --rtd-3 flag?

Without the flag, power saving works as intended.

$cat /proc/driver/nvidia/gpus/0000:01:00.0/power                                                                         ✔ 
Runtime D3 status:          Enabled (fine-grained)
Video Memory:               Off

GPU Hardware Support:
 Video Memory Self Refresh: Supported
 Video Memory Off:          Supported

Should I close this issue, as removing the --rtd3 flag solves the problem?
