X Server 1.21.1.1 crash on startx with nvidia driver 495.46

Graphics / Linux Linux
5

Hello, I am also seeing the same behavior. For specifics I am running:

  • A fully updated Arch Linux install (most recent kernel, etc)
  • The MATE desktop environment with lightdm as the launcher
  • Nvidia drivers

The behavior after updating to 495.46 is that when I boot into the machine, I get the graphical lightdm GUI. However, when I put in my auth creds to log in, the screen goes blank for a second, and then I get a fresh login screen. X appears to be crashing and dumping core when this happens.

I am attaching several files in the hopes they help.

  • nvidia-bug-report.log.gz generated with sudo nvidia-bug-report-sh
  • Xorg.coredump.txt generated with sudo coredumpctl info <pid> where <pid> was grabbed from coredumpctl list | tail -1
  • Xorg.coredump.bin.xz generated with sudo coredumpctl --output=/home/${USER}/Xorg.coredump.bin dump Xorg && xz Xorg.coredump.bin

As with the other folks reporting this, if I downgrade back to the 495.44 drivers, everything starts working again per normal. The same behavior has been seen for the vanilla and -zen versions of the 5.15.7, 5.15.8, and 5.15.10 kernels (so I have tested across six kernels total).

If I can provide any additional information, please let me know. Thanks!
