Public bug reported:
System information:
Ubuntu 18.04.2 LTS
kscreen version 4:5.12.7-0ubuntu0.1
Kernel: Linux pcalice57 4.15.0-52-generic #56-Ubuntu SMP Tue Jun 4 22:49:08 UTC
2019 x86_64 x86_64 x86_64 GNU/Linux
AMD Radeon Pro WX 2100 with two screens (HP LP2475w) on displayport, running
amdgpu pro drivers
Problem:
Once the screens get switched off by the energy saver of KDE (Option: Screen
energy saving in Energy Saving system setting), continuous messages appear in
the syslog of the screens being connected and disconnected. Please find a short
excerpt of the log messages here and longer attached as file. Messages given
from kscreen.xrandr flicker between connected and not connected several times
per second.

Several times X11 did not wake up from this, unfortuantenly I cannot
provide the useful debug information for the latter. However, already
this continuous flickering seems not correct.
Many thanks for any ideas on this.
