Description Robby Engelmann 2016-05-15 16:40:20 UTC 
I bought a Tuxedo Infinity Book v2 with Intel Skylake i7. All expect for HDMI is working fine...

Reproducible: Always

Steps to Reproduce:
1. plugin HDMI to a TV set
2. plugin HDMI to the notebook with running KDE
3. sometimes it is necessary to move a windows over to the second screen to trigger the bug, sometimes only plugin is enough 

Actual Results:  
system freezes completely. I cannot switch to another virtual console. Only by pressing the power button for a few seconds shutdown notebook.

Expected Results:  
working setup with HDMI plugged in

some info from journalctl:

Comment 1 Robby Engelmann 2016-05-15 16:43:10 UTC 
I also played a bit with different renderer settings:
openGL 3.1 GLX and OpenGl 2.0 GLX with smooth or accurate settings --> all results in freeze
installed Mesa and intel git snaps from Tumbleweed Pontostroy repo.
Comment 2 Robby Engelmann 2016-05-17 09:07:11 UTC 
no bug in KDE. With kernel 4.6 rc7 this problem was resolved
Comment 3 Sebastian Kügler 2016-05-24 15:10:21 UTC 
Good to know. Thanks for the report, anyway!
