I’ve run into a problem where my system freezes if I run certain video games without Vsync enabled when using Prime offloading.

After some digging I found out that prime-synchronization does not seem to be enabled for my main display and trying to enable it nets me this:

$ xrandr --output eDP-1 --set "PRIME Synchronization" 1X Error of failed request:  BadName (named color or font does not exist)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  11 (RRQueryOutputProperty)
  Serial number of failed request:  50
  Current serial number in output stream:  50

My first guess is that it requires nvidia drm to be enabled, which is where I encounter this weird issue, currently without the commandline option to enable nvidia drm it seems like it is enabled:

$ journalctl -b 0 | grep drm

However, if I update grub to include nvidia-drm.modeset=1 and restart, X will fail to launch.

Here is a link to the Xorg log file for the failed launch: Hastebin: Send and Save Text or Code Snippets for Free | Toptal®

Same here,

I was trying to put
nvidia-drm.modeset=1 in /etc/default/grub,
options nvidia_drm modeset=1 in /etc/modprobe.d/nvidia-drm.conf

but when restarting, lightdm fails to init

I need this to use GitHub - elFarto/nvidia-vaapi-driver: A VA-API implemention using NVIDIA's NVDEC on firefox.
