I believe I have the similar error.

Cross-posting my old debug session.
At the time of debugging I've used the "linux-zen" and "nvidia" packages from arch repository. However, I didn't used nvidia-dkms package, and I'm also not sure if I had the "linux-zen-headers".
The error itself is still persists afterwards, but I didn't had a chance to debug again to see if it change anything inside.

I spent some time learning how to debug using gdb. I'm getting the -1 here, which produces the error.
Stack-trace

Just in case I'll leave the strace log here. log.txt

Stack-trace

from this description , looks
va_DRI3_GetDriverNames failed,
then it will try va_DRI2_GetDriverNames , it also failed?

A work around is suggested here but would it not be better to fix this for real?
