On freshly installed Opensuse Leap 42.1 I can logon to both KDE and IceWM session. All looks good, however, when I logout, the Display Manager appears on garbaged screen. The mouse cursor disappears, but that invisible cursor is followed by black area. If I enter the password and login again, the situation continues on user X session.
switching to text mode consoles and returning back to graphic one does not help - the strange behavior remains the same.
Ctrl-Alt-Backspace does not help
systemctl isolate multi-user,
systemctl isolate graphical does not help
Only reboot helps.
