In the dmesg output there are plenty of lines like this (occurring every minute):
[Dez22 10:08] audit: type=1400 audit(1734858482.747:24963): apparmor="DENIED" operation="open" class="file" profile="snap-update- ns.snapd-desktop-integration" name="/proc/1288725/maps" pid=1288725 comm="5" requested_mask="r" denied_mask="r" fsuid=200 ouid=0 Maybe this is causing a ressource leak somewhere? For the time when I experienced the firefox issues, I also found lines like: [Dez21 23:04] audit: type=1107 audit(1734818641.252:24125): pid=1576 uid=105 auid=4294967295 ses=4294967295 subj=unconfined msg='apparmor="DENIED" operation="dbus_signal" bus="system" path="/org/freedesktop/login1" interface="org.freedesktop.login1.Manager" member="UserNew" name=":1.11" mask="receive" pid=1053881 label="snap.thunderbird.thunderbird" peer_pid=1631 peer_label="unconfined" exe="/usr/bin/dbus-daemon" sauid=105 hostname=? addr=? terminal=?'

That seems to be around the time when firefox had the hanging issues with the keyboard. Maybe the hanging issue could be related to an apparmor issue? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1975884 Title: Temporary screen freeze when gnome-shell logs "Removing a network device that was not added" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1975884/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
