Bug Description

I have a notebook with dual graphic cards: Intel+Nvidia (handled by nouveau). The miniDP port is apparently connected to nvidia since it stops working when I use nouveau.modeset=0. I am able to start a Wayland session when there's no secondary monitor connected; as soon as I connect it to miniDP the wayland session crashes and falls back to the greeter. The greeter won't even start Wayland session - it immediately crashes back to the greeter. Workaround is to use the Xorg-based session which works properly with secondary monitor.

This is likely a known crash. We just need to figure out exactly which known crash...

Please look in /var/crash for crash files and then upload the relevant one(s) using this command:

  ubuntu-bug /var/crash/YOURFILE.crash

Then let us know the ID of the newly-created bug(s).

Changed in gnome-shell (Ubuntu):
status: New → Incomplete

Thank you very much for your quick reply! There are in fact two crash report files:

$ ubuntu-bug /var/crash/_usr_bin_Xwayland.1000.crash

reported that it's already reported as https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1731911

$ ubuntu-bug /var/crash/_usr_bin_gnome-shell.1000.crash

I've reported this one as https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1755671
