GPU no longer detected on Ubuntu

I have a Dell XPS 15 (9560) laptop and recently updated to Ubuntu 22.04.1, and my Nvidia GPU is no longer visible as a VGA Controller, only as a 3D Controller. I’ve re-installed drivers and have played around with xorg conf files to no avail. I’ve used prime-select to select nvidia, and rebooted, and still nothing.

I’ve attached my log file, thanks.

My log doesn’t want to upload… so here is some information:

Might be broken. Which kernel version are you running?

Hi generix

$ uname -r

$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module 520.56.06 Thu Oct 6 21:38:55 UTC 2022
GCC version:

I don’t have much experience in these areas but I’ve read many many of the other issues in the forum and your advice and my current guess is either Ubuntu 22.04 issues or my gpu is broken… I did have windows dual booted but uninstalled it when doing a clean ubuntu install to try and debug this problem. I probably should re-install and check error codes…

I don’t know of a specific issue with that kernel version. I guess installing windows to cross-check might be a good idea, check device manager for “Code 43”
Otherwise, try to upload the bug-report.log again, possibly unzipped.

Good call, I don’t know why I didn’t try that… If there’s nothing of note there I’ll try Windows install next, thanks very much

No underlying errors in the logs, you already tried different drivers. I’d say it’s broken.
