I have Intel NUC with Ubuntu 18.04 which operates as server the most time. Sometimes SSH is not enough and I need to control it using Team Viewer. This is why I installed and set up xserver-xorg-video-dummy because Team Viewer requires some display. Everything is working fine but when I want to connect physical display (to control server without network) dummy display does not allow to use physical display and monitor is saying there is no signal. Is there a way to configure Ubuntu to use both displays physical and dummy but to make physical display the most wanted? I mean when I connect it Ubuntu uses it, when disconnect Ubuntu switches to dummy.

My working config for dummy /etc/X11/xorg.conf is the following:

# This xorg configuration file is meant to be used
# to start a dummy X11 server.
# For details, please see:
# https://www.xpra.org/xorg.conf

# Here we setup a Virtual Display of 1920x1080 pixels

  • dumb question, did you make sure to disable wayland/ log into a xorg desktop by default? – tatsu Mar 27 '19 at 12:58
  • also would you be open to trying with : xvnc or xvfb, that being said either of those will probably also require you to be in xorg mode, not wayland – tatsu Mar 27 '19 at 13:21
  • I'm having the same issue with Mint 20. Have you found a solution? – Jack Lilhammers Mar 22 '21 at 20:19

    By the way I've found this other question https://askubuntu.com/questions/1229168/video-dummy-the-fake-display-with-without-monitor-connected-at-the-same-time that has one answer – Jack Lilhammers Mar 22 '21 at 20:33
  • Currently I don't use dummy display and Team Viewer. I'm using xrdp which allows headless remote desktop https://askubuntu.com/a/1409120/45969 – dmitry1100 Feb 23 '23 at 16:25
