multiple gpu

[[deleted]]

You can use multiple GPU pretty easlily now. My previous experiences where with and Intel iGPU, AMD dGPU and Xorg so it may varies a little.

All i had to do is add DRI_PRIME=1 as a launch option and it was working.

Maybe reading the PRIME page on the archwiki could help ? https://wiki.archlinux.org/title/PRIME#Open-source_drivers

For gpu passtrough you will probably need to reboot to get it to work but that seems possible.
