the ACPI key for the video button is: ibm/hotkey HKEY 00000080 00001007
so if you install this application as /root/bin/switch-display, you need to edit /etc/acpi/events/ibm-videobtn and set action=/root/bin/switch-display
restart acpid using "/etc/init.d/acpid restart" (or reboot) and you should have a working way to switch video output.
