I just ran an update, as one does with apt update and upgrade. Afterwards all my monitors, bedies that one ancient 4 by 3 monitor stopped working. That 4 by 3 displays gnome at a lower resolution then usual. So I assumed that this has something to do with the nvidia drivers (has happened many times before). So I run nvidia-detect and get a really interesting output: marty@MartyPC:~$ nvidia-detect Detected NVIDIA GPUs: 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP104 [GeForce GTX 1060 6GB] [10de:1b83] (rev a1)
Checking card: NVIDIA Corporation GP104 [GeForce GTX 1060 6GB] (rev a1) Uh oh. Failed to identify your Debian suite.
“Failed to identify your Debian suite” Uh oh, that sounds bad. This is Debian 12, so I assumed this was apparent… neofetch still says it’s Debian 12!
I also made a post today trying to fix my desktop icons, so maybe the things which happened there kinda give away some hints?
Does anyone have an idea on what might be going on here?
Thank you very much for your answer. I was not aware of the dist-upgrade being required now, so I did that, but unfortunately it did not change anything after a reboot. I reinstalled nvidia-detect to see if that caused any issues, but that did not seem to be the case. Your last step I actually already did some time ago, and I tried to do the same no. Unfortunately that also did not seem to have fixed the problem. The nvidia graphics settings software is still installed, but it only shows some very limited control options compared to how it used to be. This is what that program looks like now:
So this really seems to be more of an nvidia issue, rather than a gnome one.
