No GUI after upgrade from 22.04.1 to 22.10 (but kernel 5.15 works)

[Heinrich Bjerregaard]

I am running Ubuntu 22.04.1 on a VM under TrueNas.
After upgrade to 22.10 I just ends up with a black screen, however, everything else like mail, dns, dhcp and apache2 works well.

I am using x11vnc and in the 'journalctl -b' it seems that a display cannot be achieved.

In the boot menu I have
 *Ubuntu, with Linux version 5.19.0-23-generic
  Ubuntu, with Linux version 5.15.0-52-generic

However, if I am booting 5.15.0-52 everything is OK.

Thanks for the bug report.

Please try using:

  sudo journalctl -b-1 > prevboot.txt

or similar to collect a log from the failed boot with kernel 5.19.

Also while using kernel 5.15 please run:

  journalctl -b0 > oldkernel.txt
  lspci -kv > lspci.txt

and attach the resulting text files here.

Unfortunately I did a lot of trial and error attempts to get my GUI back.
I installed linux-image-unsigned-5.19.0-21-generic, however, with same bad result.
During the fight I lost the image 5.15.0.
Another thing I did was upgrading TrueNas from 12.1 to 13.0-U3.1.
This process clears all the ZFS caches. Whether this has any impact upon a VM, I don't know.

So I did end up with the images 5.19.0-21 and 5.19.0.23 and they both boot ok.

Since I have been confused and inconsequent in my testing, I think you should mark the bug as an user error.

I am sorry for making this noise.

OK if kernel 5.19 works now then we can close the bug. Feel free to open new bugs for any problems you find.
