@peter-drealm: Seems to be another problem for you. The package xserver- xorg-core is installed and /usr/bin/X is present.
Currently i am fixing it by removing the hdmi cable from the graphics card (one monitor) and the login screen apears. Before loging in i reconnect the monitor and it will be automatically used in KDE without setting it up again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1563048 Title: Kubuntu login screen not displayed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sddm/+bug/1563048/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
