Hi all,

I'm using a Lenovo Y510p which I recently upgraded to Tumbleweed.
Everything worked fine till I tried to connect my second Monitor via the HDMI Port. When the monitor is connected I'm not able to login to KDE anymore.
After entering the login credetionals the openSUSE "progress bar" appears and after half of the progress both screens turn black and I'm dropped to the login screen again.

The same issue appeared when I tried to connect the monitor after the successful login: The screen turned black and I was droped to the login screen again.

Any hints?

Thanks in advance!
