I have 2 displays and used to have 1 big desktop. Now after the last upgrade, my custom settings are not used anymore and I cannot change them using the gnome-display-properties.
- The mirror function keeps being active even when I un-select it.
- The detect screens function doesn't do anything.
- xorg.conf is missing in /etc/X11.
What could be the cause of this unwanted behaviour?
