On a Macbook pro early 2011, I have Ubuntu 21.10 (64-bit X11 Gnome 40.4.0)
mac2011-linux% snap list|grep gnome
gnome-3-28-1804 3.28.0-19-g98f9e67.98f9e67 161 latest/stable canonical* -
gnome-3-34-1804 0+git.3556cb3 72 latest/stable/… canonical* -
gnome-3-38-2004 0+git.6ba6040 76 latest/stable canonical* -
but I have observed the problem before with Ubuntu 21.04: once a day or so, the desktop freezes, only the mouse moves but nothing else responds.
Workaround: ssh into my session from another machine and killall -u me. I believe this shows it is a problem with Gnome only.
I think I have tracked the crash in /var/log/syslog:

Can you confirm the problem? Do you have a better solution? Should I report a Gnome bug?
