Xorg crashes after in-place upgrade to debian 13: unw_get_proc_name failed: no unwind info found

tanky0u · August 13, 2025, 7:29am

I did an in-place upgrade for one of my debian-12 templates. The update process went well without an error. But after the update finished and I was getting ready to restart the template, I tried to open another xfce-terminal on the template, and all of a sudden the fonts got broken to some georgian-kyrillic looking symbols. I restarted the template in question and I cannot even start xfce-terminal now. Even though the RAM and CPU readings of the template look nominal (4 GB RAM, and 1-5% CPU utilization).

This is a template with nvidia-driver package that was installed. It got updated its version from 535 (bookworm-backports) to 550 (trixie). During the upgrade I also saw it rebuild the kernel -dkms stuff related to the nvidia drivers as well.

Any ideas what might’ve happened? How may I get a terminal into the template now to start debugging this?

tanky0u · August 13, 2025, 7:36am

I was able to open a terminal into the template by doing the following:

dom0 terminal:

qvm-shutdown --wait debian-12-xfce-gpu
qvm-prefs debian-12-xfce-gpu debug true
qvm-console-dispvm debian-12-xfce-gpu

I get a terminal in a new disposable qube, prompting me to login. I login as the user. And I am able to run shell commands in the template now. But still, I cannot use the little blue qube tray icon > debian-12-xfce-gpu > Run terminal command. It doesn’t do a thing. Also Open File Manager from the same menu do nothing as well. How to start debugging what might’ve gone wrong?

tanky0u · August 13, 2025, 7:44am

From dom0 terminal, I try this to get a terminal open on the template:

qvm-run debian-12-xfce '/usr/bin/xterm -geometry 100x30'

but no xterm window pops-up this way. I think something’s broken with qvm-* stuff in that template. Where to start debugging?

Checked the status of qubes-qrexec-agent.service. It is enabled and running (all green status on systemctl output).

The status of qubes-gui-agent.service returns failed. Did nvidia-driver package and its dependencies installation break something with my X server stuff or something?

I notice this when I check the output of sudo update-alternatives --display glx

glx - auto mode
link best version is /usr/lib/nvidia
link currently points to /usr/lib/nvidia
link glx is /usr/lib/glx

Also here are the priorities:

/usr/lib/mesa-diverted - priority 5
/usr/lib/nvidia - priority 100
/usr/lib/nvidia/bumblebee - priority 95

My suspicion is that the debian-13-gpu template I have is trying to use nvidia drivers to display windows (like xfce-terminal or the file manager), meanwhile I do not attach the GPU hardware I have to that template, but to a gaming or video qubes that use it as the template.

In the template, I set the glx to mesa:

sudo update-alternatives --config glx

then pick the number that represents /usr/lib/mesa-diverted. I restart the template. It restarts. But trying to open an xfce-terminal still fails silently without a visible error only that no terminal window ever opens up in front of me.

Installed xserver-xorg-video-dummy package. Restarted the template. Nothing changed, still cannot start an xfce-terminal on the template.

Here’s the journalctl log from the failing systemd service:

Would you please try in-vm kernel and see if fixes the issue.

It is in qube settings → Advanced → Kernel → Kernel drop-down → (provided by qube).

tanky0u · August 13, 2025, 9:28am

If I select (provided by qube) for the kernel I get libxenlight failed to create qube error.

tanky0u · August 13, 2025, 9:55am

@alimirjamali do you have nvidia-drivers on your debian-13 templates? I am starting to suspect there is some sort of incompatibility between nvidia-drivers package on trixie and qubes-gui-agent stuff. Everything was working on debian-12 bookworm-backports version of nvidia-drivers package tho.

alimirjamali · August 13, 2025, 9:56am

Actually no. I do not have a discreet GPU on this system. I suggest to edit the forum topic to include this (so the people who are more familiar with it would help).

tanky0u · August 13, 2025, 9:58am

OK. Edited the thread topic.

tanky0u · August 13, 2025, 10:16am

I am also noticing this bug in my template: `efi.mount` unit fails · Issue #8954 · QubesOS/qubes-issues · GitHub , which is also mentioned in this thread: Qubes OS 4.3.0-rc1 is available for testing - #49 by kenosen

[FAILED] Failed to mount efi.mount – EFI System Partition Automount

Edit: I notice that bug on my older debian-12 templates as well. Thus it might not be pertinent to my problem at hand.

tanky0u · August 13, 2025, 1:52pm

I restored the debian-12 template of mine, before I did the debian-13 in-place upgrade.

Why is qubes-gui-agent.service failing on debian-13 template? @alimirjamali can you check your debian-13 template for the following command’s output:

sudo systemctl status qubes-gui-agent.service

alimirjamali · August 13, 2025, 1:59pm

Of course GUI agent works on mine. Without it, the only way to control it would be via console connection and qvm-run call on it will fail unless you specify --no-gui option. And it would time out unless you set the related features to specify it does not have a GUI agent.

Anybody else running debian-13 with nvidia-drivers package installed? Having this error?

tanky0u · August 13, 2025, 9:01pm

For now I fixed my problem by doing this:

sudo mv /usr/share/glvnd/egl_vendor.d/10_nvidia.json /usr/share/glvnd/egl_vendor.d/10_nvidia.json.disabled

then, restart the template and you will have qubes-gui-agent.service running normally. You will have your graphical window programs running.

However, I would appreciate if what I did is OK. I am not sure what this does or any negative effectgs it might have on other stuff.
