They are probably not as interesting as you think.

single_head:
#!/bin/bash
# use xwininfo for geometry
xrandr --output DP1 --off
xdotool search --onlyvisible "Mozilla Firefox" windowmove 326 54

dual_head:
#!/bin/bash
# use xwininfo for geometry
xrandr --output DP1 --auto --primary --output HDMI2 --auto --right-of DP1

I connect both the host and guest graphic cards to my main monitor.
When the host disable the main monitor with the single_head script the
monitor looks for other signals and switch the the guest automatically.
When the VM shuts down the monitor switch back to the host.

The linux desktop have an annoying habit of moving all windows around
when the virtual desktop size change and keep the new position when
the size change back. I eventually created those scripts to move my
regular programs to hardcoded locations. Perhaps one day we will have
windows manager that won't fuck up the desktop every time a monitor is
hotplugged but until then I use those scripts.
