@Gunnar: Confirmed! The mutter downgrade fixes it: `sudo apt install mutter=3.36.1-3ubuntu3 mutter-common=3.36.1-3ubuntu3 libmutter-6-0=3.36.1-3ubuntu3 gir1.2-mutter-6=3.36.1-3ubuntu3`.
Thanks so much! This looks like the bug was introduced in mutter between 3.36.1-3ubuntu3 and 3.36.6-1ubuntu0.20.04.2. I posted this observation in the linked mutter bug as well (in case it might help them narrow things). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1899206 Title: Tweaktool Keyboard “Additional Layout Options” not persisting on USB keyboard unplug/reconnect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1899206/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
