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.
Some questions...
What version of the OS? What display server? What machine, especially GPU? UEFI or BIOS? Have you updated your main board firmware?
The last is my top tip -- I have often found it helps with stuff like this.
It turns out that my problem was not recognizing the difference between an HDMI switch and an HDMI KVM. As I mentioned in the previous post, the KVM provides peripheral emulation, which makes the computer think there is a monitor there even if the other port is selected. I purchase an IOGEAR 2-Port HDMI Cable KVM Switch ($59.80 from Amazon) that works perfectly. Again, I apologize for not realizing that the HDMI switch should so completely disconnect the monitor that the computer thought it was disconnected.
