Correct erroneous dual monitor position in Xfce
Posted on Jul 22, 2020 by kingbeowulf
For many years I used nvidia drivers and utilities along with an xorg.conf to set up 2 to 3 monitors on KDE and Xfce. Recently I switched to the new AMD NAVI GPUs (RX 590 and RX 5700 XT) and the new Slackware-current amdgpu driver stack. In KDE, setting up dual monitors was easy in their display GUI, but Xfce-4.12 was problematic. No matter what I did, the second monitor was always on the virtual right side of the primaty monitor, or the primary and secondary were switched. A workaround is to invoke xrandr directly:
1xrandr --output DisplayPort-0 --primary --mode 3840x2160 --rate 60 --output DisplayPort-1 --mode 1920x1080 --rate 60 --left-of DisplayPort-0
Placing this command in $HOME/.xinitrc automates the process. This also
fixed tthe monitor jumbling when using the screensaver and/or powering
off the monitors.
