Hi all,

I was previously using Kubuntu (Ubuntu then installed KDE), now im using Kubuntu straight off the bat.

I recall when I previously used CTRL+ALT+DEL, the dialog would open to ask me which power options I wanted to use (default logout 30 seconds).
But now, nothing shows up at all, the logout doesnt even work?
I'm currently using the following settings.


If I change this to Log out without confirmation, the keyboard shortcut would work strangely enough.

Hoping someone can help, cheers!

Operating System: Kubuntu 20.04
KDE Plasma Version: 5.18.5

EDIT:
Actually a lot of things aren't working:


The only things that work here are lock session + switch users + sleep.
The others log out/shutdown/ restart all don't work!
In fact, even my avatar is not showing up properly (from the default options).
I wonder if this is because I installed Nvidia drivers recently...

The problem was due to an entirely unrelated reason.
In summary, the important logic was in /usr/share/plasma/look-and-feel/org.kde.breeze.desktop
I added done some changes in the ~/.local/share user-specific directory which had overrode the system-wide configurations - leading to loss of the features mentioned in the OP.

Pasting from another thread for completeness:

I didn't like the large Volume OSD my version of KDE had, so I added some files into my ~/.local/share/plasma/look-and-feel/org.kde.breeze.desktop/contents/osd directory to convert it into a streamlined thin line look. (https://www.reddit.com/r/kde/comment...ness_osd_size/)

But as a result, that ~/.local/share.. config took priority over /usr/shar.. and I lost all the other 'org.kde.breeze.desktop' configurations (which included my lock screen & the ctrl+alt+del logout confirmation dialog screen).

I have removed my ~/.local/share...../org.kde.breeze.desktop and put the OSD config items into the /usr/share..... directory and all is right with the world again!
