[Bug 1563048] [NEW] Kubuntu login screen not displayed

[Mike]

Public bug reported:

Since the upgrade to Xenial i have the problem that the login screen is
not appearing. I only see a blank screen on both monitors.

I am able to switch to console and login. I also looked into the
Xorg.0.log but there was no error, just nothing is shown. I tried
restarting sddm and once had luck that it worked. Now even with
restarting i can not get the login working.

Sometimes it shows the login screen but keyboard and mouse are not
working there. CTRL+ALT+DEL restart still works.

I installed gnome now besides it and now have created the bug report
from here. If i can provide additional information please let me know.

I did not have this problem in 15.10. It just started after the upgrade
to 16.04.
