Hi,
I am trying to debug an issue with my Xorg xserver. Previously, I was running Ubuntu 24.04 on Linux kernel 6.8 with no issues, with an Nvidia RTX 4090. I used the NVIDIA.run installer to install the CUDA drivers, which allowed me to use the CUDA libraries but broke my display manager and now I can only tty / ssh into the system. I am now trying to fix my display manager so I can start using a new monitor.
List of things I have tried:
- reinstalling nvidia-driver-535, 550
- uninstalling (
sudo apt purge *nvidia*
) drivers - switching display manager from gdm to lightdm/sddm (all display managers don’t start)
- using
NVIDIA.run -uninstall
(said no drivers installed, might’ve already ran this once before) - use the iGPU on my mobo (doesn’t give displayport output; I suspect underlying issue with xserver)
- run
X -configure
(giveserror: number of created screens does not match number of detected devices
) - delete /etc/X11/xorg.conf (doesn’t do anything)
- run
nvidia-xconfig
(still same issue) - run
dpkg-reconfigure xorg-xserver
(generated xorg.conf file doesn’t fix it) - create custom xorg.conf (
X -configure
on Ubuntu 24.04 keeps defaulting to /root/xorg.conf.new) - update kernel to 6.9 liquorix (kernel didn’t work)
- switch back to nouveau drivers (didn’t even give systemd output anymore when booting up)
I am trying to figure out how to fix the issue without completely reinstalling Ubuntu, as I am trying to keep my progress so far with custom systemd files, etc…
My current error is that it shows “gdm.service failed to start” when booting up, and I haven’t been able to get past it. I ran a hardware probe and it seems like the hardware is working fine: HW probe of MSI MAG Z590 TORPEDO Desktop Computer (MS-7D08) #ce291a2490. I’ve attached the most recent Xorg log file below.

Any help would be great, thank you.
