[opensuse] Enabling an external display on a laptop that shows disconnected.
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.

Don, is there a keybord combo that deals with this? My dell has such and perhaps yours does as well. I also have bios settings, but never use them on this machine but have used them on an older sony in the past. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The Quick Start Guide says the Fn+F1 will switch to external display, but it appears to have no effect. Thanks, Don -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

That sequence woke up the laptop display, bit not the external display. Do I need to put data in the /etc/X11/xorg.conf.d 50-* files? I do not know when they are read. Don -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It's possible something there might help. I don't remember your hardware. Running in Xterm or Konsole, what is output from inxi -G -c0 (install inxi if necessary), and grep onnect /var/log/Xorg.0.log ???

I installed inxi and executed the suggested commands. The output from my 42.3 system is below, where both monitors appear. But the laptop monitor was blanked and came to life after I opened the lid, but some time later. I don't know why the delay.

When I returned to my FVWM environment, and ran the commands again, HDIM-2 was shown disconnected. I will look at the man page and see what inxi does.

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.

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. -- Liam Proven - Technical Writer, SUSE Linux s.r.o.

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.
