You have been subscribed to a public bug: With up to date vivid, when I choose "Log out" from the KDE menu, the log out process hangs and does not bring back the log in screen.
I am left with either a black screen (where the cursor can still move), or if some non-KDE programs were running when I issued the log out command, they may still be running. Looking at the process list, I can see that sddm-helper has a couple of zombie childs. If I do `sudo killall sddm-helper`, the log in process completes and I can log in again.
