Thread: PLASMA shows black screen only

  1. #1

    Default PLASMA shows black screen only

    Hi folks,

    I am running openSUSE Leap 15.1 (Linux localhost 4.12.14-lp151.28.32-default #1 SMP Wed Nov 13 07:50:15 UTC 2019 (6e1aaad) x86_64 x86_64 x86_64 GNU/Linux).
    When I log in, PLASMA only shows a black desktop, no task bar or anything. I can run applications using Alt+F2, but the whole plasma environment is missing.
    Any ideas?

    Thanks

    Is this a fresh installation which you have not yet updated? Are you able to launch an IceWM session instead successfully?

    Do you see a mouse pointer? What color & shape? Can you move the pointer?

    Does right-clicking anywhere on the black screen show the Desktop context menu? (»Open with Dolphin«, »Configure Desktop« etc)

    Maybe it has to do with a missing desktop image, or with those newfangled »Activities…« I’ve never used, or with a KDE widget/plasmoid like Weather waiting for a network connection?

    Maybe the compositing doen’t work correctly with your video driver? (systemsettings5 → Display and Monitor → Compositor; try disabling it.)

    Yes, actually, I encountered the problem and decided to try a fresh installation. So I did a system upgrade (conserving my home directory), updated all packages - and ended up with the same situation.
    And yes, IceWM works. It seems to be KDE/Plasma problem.

    Yes, I see a normal mouse pointer (white standard pointer). I can also move it normally and the background is completely black. As soon as I return home, I will check the Compositor setting. One interesting thing to note is that it suddenly happened without changing any settings.

    Does the problem occur with a newly created user as well?

    Meanwhile, I checked this: the context menu is not shown.
    I also disabled Compositor now. Now it shows the standard background, but still no taskbar and no functionality...

    Yes, I was aware of the risk to conserve faulty settings - but I wanted to keep all my data safe...
    Anyway, I now created a new user - and see exactly the same behavior...
    Any ideas? Thank you very much for any hints...

    That's fine but it is necessary to figure out whether the problem is caused by some settings of the individual user or is a more fundamental one.

    So to me this looks like a more fundamental problem.

    Could you please use
    Code:
    # zypper lr -uEP
    to produce a list of your current repositories and show the result here.

    What does
    Code:
    # journalctl -b 0 -p 4
    report?
