gnome-shell crashed with SIGSEGV in meta_drm_buffer_gbm_finalize()

[Amartya Datta Gupta]

The gnome shell always starts a new session when trying to wake up from sleep. On waking up, after I enter the password, the screen turns black and the login screen appears.

Sounds like bug 1969422, but that was meant to be fixed last year:

https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1441#note_1548259

[Daniel van Vugt (vanvugt)]

I've been trying for hours and can't find a way to reproduce this bug.

Please update your system to 45.0:

  sudo apt update
  sudo apt full-upgrade

and then reboot.

If the crash happens again after that then please provide more details about the circumstances, such as:

  * If it only happens when the secondary monitor is connected
  * If it only happens when a window is fullscreen/maximized

Please also confirm your libmutter-13-0 package is version 45.0-1ubuntu1.

Separately to all that I'm waiting for errors.ubuntu.com to start working again so we can see more details about this crash from other machines.

There haven't been any reports of this since 23.10 was released so I'm going to start the clock to let it expire in 2 months...

[Launchpad Janitor (janitor)]

[Expired for gnome-shell (Ubuntu) because there has been no activity for 60 days.]

[Daniel van Vugt (vanvugt)]

Maybe this will get reopened since a very similar issue is now reported upstream: https://gitlab.gnome.org/GNOME/mutter/-/issues/3277
