The xrandr output looks correct but the attached MonitorsUser.xml.txt looks suspicious in that it confirms the monitors don't have any separate positional information. If deleting monitors.xml didn't work then next please try:

1. sudo rm /dev/dri/card0 # (should be the "Unknown Display")
2. rm ~/.config/monitors.xml
3. Log in again.

If that works then the issue is just bug 2060268. And unfortunately deleting /dev/dri/card0 will only last until the next reboot.
