You're probably right that the DISPLAY is always :0.0. You need
another way to toggle between 0 and 1. Try this:
#!/bin/bash
swfile=/tmp/sw-file
if [ ! -f $swfile ]; then echo 0 > $swfile ; fi
echo $(( ! `cat $swfile` )) > $swfile
echo exec switchscreen `cat $swfile`
Note that I just echo-ed the command because I don't have switchscreen
installed. The $(( ... )) syntax allows you to evaluate mathematical
expressions. Read "man bash"

Works perfectly! Thanks HTH :)
