laptop-mode-tools changes nvidia's prime D3 power management.

[gulafaran]

i havent exactly figured out what bits of laptop-mode-tools thats changing it but upon reboot or plugging in or out the power cord changes it.

/sys/bus/pci/devices/0000:01:00.0/power/control gets changed to "on" instead of "auto" meaning its constantly powered on. so currently i have to "echo auto | sudo tee /sys/bus/pci/devices/0000:01:00.0/power/control" on boot/AC/Battery changes. doesnt occur without laptop-mode-tools.

That would be the runtime-pm module. Here's the specific line

auto is used when wanting to conserve power. OTOH, on is used when you want to run the device full power, which is the case when on AC.

So, as you mentioned, on power plug in, it'll be on.

thanks, il modify that and add simply a line that sets nvidia to auto on AC aswell then. its mostly just generating heat and powers on by itself anyways when ran with prime-run so.

You could also try blacklisting that particular device id in `runtime-pm.conf`. s3nt fr0m a $martph0ne, excuse typ0s

does that mean adding "0000:01:00.0" to the blacklist or do i use "01:00.0" from lspci?

ok so lspci -nn lists it 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GA106M [GeForce RTX 3060 Mobile / Max-Q] [10de:2520] (rev a1)

added 10de:2520 to the blacklist, and now it works as intended. thanks man <3

I think the lspci device ids should work. Please try it out.
