Description Pavol Klačanský 2016-02-07 02:55:26 UTC 
As of upgrade to 4.4.1 the displayport output stopped working. I am using DPM and it worked with 4.4.0-r1 and previous kernels.

Please attach your xorg log and dmesg output.  Can you bisect?
Comment 2 Pavol Klačanský 2016-02-09 03:33:07 UTC 
It is strange, but I accidentally rebooted to that kernel again and it works. I probably forgot to do 'make modules_install'.
