Fix For XFCE in Boxes

[fishmanloveslinux]

A friend of mine was using MX Linux XFCE in Boxes and he couldn't get the screen resolution to autostart when he booted up the machine. Here is the fix that he came up with.
#!/bin/sh
sleep 5
xrandr --output Virtual-1 --mode 1920x1003 --pos 0x0 --rotate normal --output Virtual-2 --off --output Virtual-3 --off --output Virtual-4 --off

xrandr must be installed before attempting this.
