I set gnome-shell as the affected package for now, since a theory would be that the changed behavior is related to some upgrade of that package.
@Weston: To find out, can you please downgrade gnome-shell temporarily: sudo apt install gnome-shell=3.36.1-5ubuntu1 gnome-shell- common=3.36.1-5ubuntu1 Then reboot and let us know if the issue is still present. ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- 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
