    Default Switch user does not work

    Just installed 15.2 on a Compaq Presario, 4GB.
    Works fine, except switch user does not work.
    I click on "Lock screen" and in the following window I click
    on "Switch user". Results in black screen.
    I can go back to the prevoius session by hitting control-alt-f7, but if
    I try switch user again everythiing hangs.

    Thanks for a hint,

    As far as I know this is a functionality of the desktop. So telling which desktop you use mught be crucial to get any useful help.

    OK, Kde Plasma
    I have two users and I can login to each of them. To get from one user to the other
    I first have to logout the first.

    I just tested this, and it seemed to work. I selected "Switch User" from the menu.

    It was a bit confusing, probably because I was using GDM to manage the login screen. So I switched to SDDM and rebooted. Then I tried again, and it was less confusing this time.

    @akeblomberg:

    I'm currently in the situation that, switching between Leap 15.2 KDE user sessions where Akonadi isn't running works perfectly but, if a user which has Akonadi running is in the set of users being switched between then, the system begins to be painfully slow and unstable.

    As you can see, the CPU ain't puny and, there's more than enough fast memory available.

    My current solution is: don't setup and switch between multiple KDE user sessions if, one of the users has Akonadi running …
