Hi, since some days my laptop does not allow to login after reboot. I always have to open a console (CTRL-ALT-F1) and execute a "systemctl restart display-manager" in order to be able to login. Two different scenarios: a) after boot I can see the NVIDIA logo for a second and then (instead of showing the login prompt) I get a blank screen. "systemctl status display-manager" then shows: display-manager.service - X Display Manager Loaded: loaded (/usr/lib/systemd/system/display-manager.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Thu 2017-03-09 08:00:05 CET; 2min 53s ago Process: 1900 ExecStop=/usr/lib/X11/display-manager stop (code=exited, status=0/SUCCESS) Process: 1519 ExecStart=/usr/lib/X11/display-manager start (code=exited, status=0/SUCCESS) Main PID: 1597 (code=exited, status=1/FAILURE) Mar 09 08:00:00 t510w systemd[1]: Starting X Display Manager...
