Bug description:
[ Impact ]
GNOME Wayland session crashes with
libmutter:ERROR:../src/core/window.c:...:meta_window_get_work_area_for_logical_monitor:
assertion failed: (logical_monitor)
Upstream Mutter release 46.1 resolved ONE cause of this assertion
failure, but apparently not all causes. So we are separating the two
scenarios of Tiling Assistant active and disabled. The Mutter fix only
addresses the crash when Tiling Assistant is disabled.
[ Test Plan for the Mutter fix ]
This needs more detail and community help...
On a machine that was previously affected by the crash...
1. gnome-extensions disable tiling-assist...@ubuntu.com
2. Disconnect the HDMI cable
Expect: The shell has not crashed and continues to function.
[ Test Plan for the Tiling Assistant fix ]
TODO
[ Where problems could occur ]
Potentially anywhere in Gnome Shell. Judging by the fix it relates to
automatic window placement when monitors are added and removed.
[ Original description ]
I am observing multiple issues with external monitor in a hybrid
system (laptop) with Intel GPU and NVIDIA GPU in a Gnome session:
- Disconnecting HDMI cable crashes the desktop to login screen
The HDMI port is connected to NVIDIA. I use the latest updates and
drivers of 22.04 LTS.
I am not sure how to auto-report this with ubuntu-bug. The system is
similar to this report:
