After experiencing a loss of dual screen support because of an upgrade I now can’t restore my normal monitor arrangement. The dual screen issue is partially resolved except for this.
I have my external monitor set up to the left, but when I choose this option windows maximise across both screens. This does not happen if I set up the external monitor to be on the right. Specifying the external as my primary display does not help. I experience this on both xfce4 and gnome desktops, so I think is something underlying is broken.
Additionally the screen profiles I had stored in
xfce-display-manager got deleted when I was trying to make new ones. If I try to remake a profile with same name as one of the old ones it tells me that profile already exists. I’ve tried moving
~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml to a temporary directory and logging back in again, but that did not help. I also tried logging into a clean account with no xfce settings and still get the same virtual desktop behaviour.
I used to use a script calling
xrandr but these no longer seem to be the relevant underlying commands to bypass incapable desktop environment GUIs.
Does anyone know what to try or how to fix this?
