Package: gnome-shell
Version: 48.1-1
Severity: normal
Dear Maintainer,
I have a weird setup on an external SSD that I use for testing kernel
changes on multiple devices. There, the GNOME session recently started
to crash when I used the touchpad or a mouse on some devices, but not on
the GDM screen or on a new user.
I tracked it down to /org/gnome/desktop/interface/cursor-size dconf
value somehow being set to zero (possibly by XFCE), and this triggering
an assertion in libmutter:

Attaching a journalctl log where I booted with the value being set to
zero, logged in from GDM leading to the crash, then set the value to 24
from ssh and logged in again to a working session.
Thanks,
Alper
