Quest 2 owner here, your best bet is trying ALVR as virtual desktop straight up doesn’t support Linux, but honestly YMMV. I daily drive linux and have done so for awhile now, I’ve found performance for most games these days, usually runs on par with Windows. But I found the performance for VR much much worse (with a 6700xt}. . Not to mention I was getting a long standing bug that valve hadn’t fixed in fucking years on SteamVR in linux the last time I tried it. Although maybe that’s changed since SteamVR 2.0.
I’d happily try again if my quest 2 didn’t have mad stick drift and no amount of cleaning the contacts seems to be fixing it :(
