SUMMARY

For one of my clients, I manage Linux VDIs on the side. These VDIs are based on Ubuntu 20.04, and users are free to choose between GNOME (default), MATE and KDE desktops. Most of the users have opted for the Kubuntu desktop. In a testing environment, I am testing an upgrade to Ubuntu 22.04. For GNOME this goes fine, however for KDE there's an issue with kscreenlocker. It seems as though once the screen has locked, input (both keyboard and mouse) does not trigger the unlock/password box in order to unlock the screen.

This is observed both through the VMware horizon client that users need to use to log in, but also when viewing the VDI directly in VMware ESX


STEPS TO REPRODUCE
1.  Install Kubuntu 22.04.1 LTS on VMware ESX
2.  Use VMware Horizon View to log into the Kubuntu VDI
3.  Once passed GDM (sadly, this is required by VMware Horizon), use the KDE Desktop normally
4.  Lock screen, and observe that an unlock window is not displayed

OBSERVED RESULT

The lock screen wallpaper is displayed, but both keyboard or mouse input do not trigger the password/unlock dialog to unlock the screen

EXPECTED RESULT

Keyboard and mouse input trigger the password/unlock dialog

Comment 3 Jeffrey Bouter 2023-01-06 15:15:39 UTC
The issue has been resolved. During the upgrade, new config files aren't installed. Therefore, the locking theme is broken because it still uses the config file for Ubuntu 20.04 instead of 22.04.

I was using --force-confdef in combination with --force-confold, changing the latter to --force-confnew seems to resolve the issue.
