Bug description:
[ Impact ]
Touch input will crash the desktop session when an application has
requested pointer constraints or pointer lock.
gnome-shell reports: libmutter:ERROR:../src/wayland/meta-wayland-
pointer-constraints.c:565:meta_wayland_pointer_constraint_deactivate:
code should not be reached
This is fixed upstream in
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/3889
[ Test Plan ]
0. Set-up a touchscreen machine with Ubuntu Desktop 24.04 LTS
0. Install the update from noble-proposed, and reboot
1. Download the attachment "bug-2090824.html"
2. Open "bug-2090824.html" in firefox.
3. Follow the instructions on the webpage, that is:
3.1. Click anywhere in the page with the mouse or touchpad
3.2. Using the touchscreen, drag the finger around the page
3.3. Move the cursor with the mouse or touchpad
4. Verify that the desktop did not crash, and that you were not logged-out.
[ Where problems could occur ]
mutter is the Wayland compositor library that provides graphics and inputs
for the GNOME desktop, thus is a critical component.
Problems could manifest with mouse/touch input not working anymore, or sudden
log-out if gnome-shell crashes.
[ Original bug report ]
Laptop is Dell XPS 13 (9370), with i7-8550U CPU with internal
graphics, and with touchscreen.
Quite commonly the whole session crashes with error log looking like:
gnome-shell[2473]: #0 647e91fc7678 i
resource:///org/gnome/shell/ui/init.js:21 (2afcdb070bf0 @ 48)
gnome-shell[2473]: == Stack trace for context 0x647e91f03d20 ==
gnome-shell[2473]: GNOME Shell crashed with signal 6
gnome-shell[2473]: Bail out!
libmutter:ERROR:../src/wayland/meta-wayland-pointer-constraints.c:565:meta_wayland_pointer_constraint_deactivate:
code should not be reached
gnome-shell[2473]:
libmutter:ERROR:../src/wayland/meta-wayland-pointer-constraints.c:565:meta_wayland_pointer_constraint_deactivate:
code should not be reached
gnome-shell[2473]: **
and takes the whole desktop session with it.
This is possibly upstream
https://gitlab.gnome.org/GNOME/mutter/-/issues/3487 issue.
