john at thunderguard:~/.screenlayout$ cat twoscreens2.sh
#!/bin/sh
xrandr --output DisplayPort-3 --off --output HDMI-3 --mode 1920x1080
--pos 1920x0 --rotate normal --output DVI-0 --mode 1920x1080 --pos 0x0
--rotate normal
john at thunderguard:~/.screenlayout$ ./twoscreens2.sh
xrandr: cannot find mode 1920x1080
