I am running opensuse Leap 15 on an Alienware laptop. When I plug a

I get the system to send an event or something so it will look and see
that a monitor is there. If I cycle power on the computer with the
monitor connected both monitors come up connected. The command xrandr
--auto does not bring the disconnected monitor to life. The output of
xrandr on the system with both monitors is:

Sorry, problem with setup. I tried to use an HDMI switch to connect my
monitor between two computers on my desk while debugging. I forgot about
the peripheral emulation feature provided by KVMs, not provided bu a
switch. So I have ordered a 2 port KVM to replace the switch.
