Plasma no longer boots: Could not load the Qt platform plugin “xcb” in “” even though it was found



  • Manjaro KDE just upgraded to Plasma 5.21 with QT 5.15.2.

    A friend of mine that uses Manjaro KDE told me that after today’s update, when he entered his password, the desktop was no longer initializing.

    So I updated one of my computers myself, one that uses auto-login, and I got this:

    When starting plasmashell from the tty I got:

    Could not load the Qt platform plugin “xcb” in “” even though it was found.
    

    The journal shows a problem with libc:

    And the sddm.service shows:

    Auth: sddm-helper exited with 1
    


  • Fixed by removing kwin-lowlatency, and installing kwin.

    They are telling me that the official kwin now has the benefits of lowlatency too.
