I'm running Ubuntu 22.04.3 LTS on a HP laptop 15-db0598sa. It is fully up to date with the latest drivers etc, but I cannot boot into 5.15.0-88-generic, as the GUI gives a black screen with the occasional flashing white line when I choose it from the GRUB menu.

The previous version I have on there (kernel 5.15.0-84-generic) boots correctly and the GUI does work. I did think it was an issue with the previous version (5.15.0-86-generic), but upgrading has not changed behaviour.

How would I go about diagnosing what the issue is with graphics in the new version of the kernel?

I note that a previous kernel version has had issues with graphics Ubuntu no longer boots with kernel 5.15.0-53-generic - how to troubleshoot?, but this is now with 5.15.0-88-generic.

EDIT: I have found this bug on launchpad affecting AMD Radeon graphics: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2042772, which this laptop has

Second edit: It still occurs with 5.15.0-89-generic kernel.

  • Due to that fact that I'm on 20.04.6 ($ cat /etc/os-release), fully updated, but "still" running 5.13.0-52-generic: I'd guess that you have manually installed kernels which do not fully support your system software. See - https://www.google.com/search?channel=fs&client=ubuntu&q=ubuntu+kernel+versions - I'd say you have installed the 22.04 kernel, which may well cause your trouble. – Hannu Nov 11 '23 at 20:40
  • It is 22.04.3 that I'm running - thanks for pointing that out. – user36196 Nov 12 '23 at 11:14
