Disable screensaver / monitor power saving when using a specific program

This suggestion seems good, there’s just some minor issues to solve.

Script currently looks like this:

#!/bin/bash
pgrep Ardour >/dev/null

if [[ $? -eq 0 ]]
then
    xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/presentation-mode -T
else
    notify-send "ardour is not running!"
fi
