            Bug ID: 462626
           Summary: Dual Monitor setup: Primary Display does not wake up
                    after energy save mode
    Classification: Plasma
           Product: KScreen
           Version: 5.26.3
          Platform: Manjaro
                OS: Linux
            Status: REPORTED
          Severity: major
          Priority: NOR
         Component: common
          Assignee: kscreen-bugs-n...@kde.org

  Target Milestone: ---

I am using 2 Displays: One is connected as primary on DP4, the other one is a
secondary display in another room, connected via HDMI1.
When the displays are powered off due to energy saving schedule, the primary
display does not wake up again. When triggering the wake up (mouse movement,
key input), the displays both get powered up again (as can be seen by the
stanby LEDs), but the primary stays black. In the .local/share/kscreen config
file, the line with "enabled" seems to be stuck at "false".

Once I manually unplug the second display (HDMI1), the primary display shows
the desktop again.
