Discrete graphics turn on after suspend about system76-power

[crawfxrd]

Is this still reproducible? If so, do you have logs for this?

For some reason in Pop os 18.04 doesn't work automatically after suspend. Only if i run it manually works.
Any clue?

To confirm:

• system76-power graphics power reports off before suspend?
• system76-power graphics power reports on after suspend?

What computer model do you have? And is this reproducible every suspend?

[MrSquaare]

To confirm:

* `system76-power graphics power` reports `off` before suspend?

* `system76-power graphics power` reports `on` after suspend?

What computer model do you have? And is this reproducible every suspend?

This is indeed what happens, status off before suspension, status on after suspension and it's reproducible at each suspension

My computer model is a Lenovo Y540, the graphics card is a NVidia RTX 2060

I would assume some script is rescanning the PCI bus on resume. I know we have one script (system76-thunderbolt-reload) that rescans the PCI bus on resume, but this is limited to our darp6 and galp4 models which don't have dGPUs.

grep -rw rescan /lib/systemd/system-sleep

grep -rw rescan /lib/systemd/system-sleep

I don't know if I was supposed to execute the command or not, but I didn't get an output

I can confirm this issue on pop os 20.04.
On system start it remains power off.
On resume from sleep it shows power on.

It looks like this is still an issue in pop os 20.10. Are there any plans to fix this?

Arch Linux user chiming in here that this happens on my gaze14. I keep my laptop in integrated mode and keep my dGPU off, because I take it to class, where it runs on battery. When I shut down before, the dGPU is off and the graphics mode is integrated. When I power back up, it's still in integrated mode, but for some reason, the dGPU is on.
