I'm trying to add a fake monitor in Ubuntu 16.04. This is a headless system and the problem is that remote desktop like teamviewer are really slow, so I tried the accepted solution here:
Add Fake Display when No Monitor is Plugged In
Now is properly working when is headless, but as soon I connect a real monitor, it doesn't work anymore (get stuck at boot), unless I delete xorg.conf file (as suggested in the comments in the link provided).
Any other solution?
Hardware dummy plug is not an option.
