We are currently experiencing an issue with our KDE, Plasma v5 on our Ubuntu 22.4.5 LTS VMs.
The connection is made via Horizon. When the user locks the VM, they do not see a lock screen, but still see the unlocked desktop. All inputs are intercepted, the clock and all notifications continue to run. The only solution here is to unlock the session via “loginctl unlock-session {Session-ID}”.
For one user, this happens every time they lock the VM using a keyboard shortcut, while for other users it only happens sporadically every few weeks.
Does anyone have any ideas?
