Hi,
Thanks for your quick reply.
Some information you requested:
- I indeed use Linux. More specifically: Ubuntu, 20.04.2 LTS
- The NVidia driver version I currently have installed is 460.39
- glxgears works fine. It stabilizes around doing roughly 1000 frames in 5 seconds.
- the glxinfo output is quite large, but here you go:

Lastly, this system belongs to my institution, but is not directly connected to the overall hospital network (which puts many restrictions on the computers for most users as you probably know). So it’s a seperate computer that belongs to our research group. Nothing notably unusual about the set-up.
