Graphical interface problems after update

Hello,

i updated dom0 with the dom upgrade tool.
After i rebooted my computer, the password prompt for the encrypted luks disk changed from the qubes design to the default linux(?) layout (https://imgur.com/a/bjIweE8).

After entering the password for the luks disk qubeos starts until it gets stuck at “Starting plymouth-quit-wai… until boot process finishes up…”.

Access to dom0 is only possible with the tty.
I have in my log the same “PAM unable to dlopen…” as in the issue in github dot com QubesOS qubes-issues issues 8595 and a exception from python: https://i.imgur.com/4JDaYsL.png
The second part can be seen here: imgur dot com eUSjhWM

Is there any way how i can restore the “old” password prompt for luks, and get a graphical interface of dom0?

Hi user8121 – and welcome to the forum! :slight_smile:

Can you share the make/model/name of your graphics card? – it sounds like the Framebuffer Console (?) somehow fails with the latest update.

Does your installation enable you to boot an older kernel (from the GRUB menu) - and does that work?

Thank you for your help :slight_smile:

I used a nvidia geforce rtx 4060. After replacing the graphics card with a nvidia 1060 it works again as expected.

When using the geforce rtx 4060 this issue occurs sadly also on all kernels that are available. I tried 6.15.7-1, 6.12.39-1, 6.12.11-1, 6.6.77-1.

I have a similar problem. i think the last firmware has a bug that result in nouveau crashing.

Hi user8121

Nice to know, that the problem is related to the graphics card … and that you can narrow it down to the RTX 4060 vs. NVidia 1060.

Sadly, I don’t have any of the cards, so I can only guess and make (silly?) suggestions … :-/

With the RTX 4060 installed, what happens if you add:

modprobe.blacklist=nouveau

to the kernel line in GRUB?

Does

rmmod nouveau
modprobe nouveau

from a dom0 terminal give any information (eg. a dmesg)?

When running sudo dmesg | grep -i nouveau -A 2 -B 2i there is a message that says


[...] gsp ctor failed -2
[...] probe with driver nouveau failed with error -2

There was a bug report for this for the 4080 2375308 – Nouveau doesn't work and also a duplicate for the 4060 2375857 – Nouveau not working due to missing firmware.

The fix is apparently available in fedora 41/42 :c .
