Lock Screen Hangs

Snowhog -

Thanks that is getting us closer. TTY 7 is hung. I opened all the others. Then locked TTY 1, which is where I boot to. I started a new X session in 2. F1 did unlock kinda. The top and bottom ribbon the screens were cut off. I tried resetting the SDDM. It didn't help. If I understand correctly. TTY 7 was the old graphical session and shouldn't be hung? I could activate and login to all the other sessions. Working from there is like a reboot. So it doesn't help me. Yet it is providing some useful information. The session can unlock.

From the Desktop open Konsole. Type w | grep -e 'tty[0-9]' and press Enter. Copy/paste the output here.

And if there is a locked tty session: https://askubuntu.com/questions/5578...locked-session might be useful.

xxx tty1 :0 17:30 6:26 14.87s 0.03s /usr/bin/startplasma-x11

So, your were right it is solveable!
sudo -i loginctl list-sessions
sudo -i loginctl unlock-session id will unlock the session and reset the interface however the programs are still running! While not elegant. It will work! Thank you

What doesn't make sense to me is that my same NVIDIA driver works with Ubuntu but not with Kubuntu. So something with light sddm. May try straight X.

Snowhog, Thank you! Appreciate you!

Glad we could find you ‘a’ solution, even if it is fuggly.
