Thank you, actually having a log to go through was very useful! Kinda. I managed to suss out that vkBasalt was having a config issue, which I eventually fixed. Now all my OS drive games seem to launch fine, except SteamVR (still).

I was able to do a little more research with info from the log and I found out running SteamVR the usual way was broken. Launching Steam from /usr/lib/steam/ makes it…sorta work.

Yeah, turns out it happened to be a separate issue from my initial problem, but with the same symptoms.

Yep, 545.29.06

EXT4. Huh, didn’t realize installing a Linux OS into an NTFS formatted drive was even a thing
