I am trying to discover how to enable an external monitor that I plug into my laptop. I am trying both 42.3 and 15. When I execute the xrandr command by itself is shows HDMI-2 disconnected. My laptop screen sometimes comes up as LVDS-1 unknown connection, where it certainly knew the connection when I started the system (should be connected primary)
I have tried various xrandr commands advertised to work, the simplest being sudo xrandr --auto. After many hours on google I always find the xrandr --auto solution. The Opensuse system settings widget only shows one display and no options to probe for others.
If I boot the system with the display attached it comes up correctly, so the monitor and cabling are good.
Any suggestion would be greatly appreciated.

I may have solved this non problem. I was using an HDMI switch to connect my monitor to two different computers. It appears that an HDMI switch will not function as a KVM. There must be some signal that a KVM keeps asserted that the HDMI switch drops. And switching the port is not the same as plugging in the HDMI cable. I find that if I select the computer and unplug and plug the port it is no longer disconnected.
