Nvidia Optimus with proprietary driver won't power down on AC #713

Closed heinthanth closed 8 months ago

heinthanth commented 8 months ago

[x] I've read and accepted the Bug Reporting Howto [x] I've provided all required tlp-stat outputs via Gist (see below)

Describe the bug

I have Nvidia Optimus setup with proprietary driver. It works well when TLP is stopped or is on BAT mode. I've read TLP FAQ and enable SOUND_POWER_SAVE_ON_AC=1. But Nvidia is not power down when laptop is connected to AC.

Expected behavior

Nvidia dGPU should be power down even on AC.

To Reproduce

Steps to reproduce the unexpected behavior:

  1. Only happens on AC
  2. Setup Nvidia Optimus with PRIME
  3. Plug AC adapter
  4. https://gist.github.com/heinthanth/ff443ef23952dc559055fbfac2deb32c

I found RUNTIME_PM_ON_AC is disabled somehow. Now, it works! Thank you!

Thanks for your feedback. Glad you were able to figure it out for yourself. I couldn't find RUNTIME_PM_ON_AC=auto in your output, so the default on must have been effective.
