Title:
gnome-shell crash on unplugging external monitor –
meta_window_get_work_area_for_logical_monitor assertion
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
While unplugging an external monitor (HDMI), GNOME Shell crashed
immediately. The session was terminated and returned to the login
screen.
I am running Ubuntu 25.04 with GNOME Shell 48.0 and Mutter 48.1 under
Wayland. This issue seems related to monitor hotplug or logical
monitor handling.
In my case, the crash most frequently occurs while a YouTube video is
playing in Google Chrome. However, it is very rare overall and
difficult to reproduce consistently. Unplugging the monitor during
video playback seems to trigger the bug more reliably.
