  • Is the xrandr output from the situation as in the image? that seems odd, since the xrandr output shows the built in screen rightmost? Did you change it afterwards? The arrangment could be made, but I'd need to know which is which. Please leave a message. – Jacob Vlijm May 30 '16 at 15:18

I run 3x1920x1200 and often have to edit ~/.config/monitors.xml to manually set their order, and X/Y pos.

*I have profiles for work and home...monitors.work.xml, monitors.home.xml
