--- Comment #6 from Michael Zapf forums18@mizapf.de --- Created attachment 137386 --> https://bugs.freedesktop.org/attachment.cgi?id=137386&action=edit dmesg output after turning the monitor back on (2nd system)
This is another dmesg output, created on my office PC with a UHD display, connected by DisplayPort.
The turn-off event occurs after time [2643.173460]. Turn-on occurs some seconds later.
System was updated the same day in the morning (openSUSE Tumbleweed rolling release, 4.15.2-1).
