[QUESTION] #124

Closed izmyname closed 1 year ago

izmyname commented 1 year ago

A silly question: do i need to enable nvidia-drm in boot parameters as described here? https://wiki.archlinux.org/title/NVIDIA

I'm asking because for some reason the output of /proc/driver/nvidia/gpus/0000:01:00.0/power returns 'Runtime D3 status: Disabled by default', even though I use rtd3 2 and /etc/modprobe.d/nvidia returns 'options nvidia "NVreg_DynamicPowerManagement=0x02"'. Maybe nvidia-drm.modprobe=1 somehow conflicts with envycontrol trying to switch runtime?

Envycontrol handles it for you unless you're on Fedora or some RHEL based distro

I removed nvidia-drm.modprobe=1 from bootloader config, rebuilt initramfs, then switched to integrated mode and back to hybrid --rtd3 2. Everything works as intended.

cat /proc/driver/nvidia/gpus/0000:01:00.0/power Runtime D3 status: Enabled (fine-grained)

Thank you!
