F8­x86_64 on the Acer Ferrari 3400LMi

Appendix B – dual­head.sh

#!/bin/bash

#

#Available at http://ferrari.databa.se/3400/f8/dual­head.sh

#A script to manipulate connected graphical outputs,

#including TV­out. It includes the most common operations

#and may also be configured to run on an XF86Display event.

#Typically Fn­F5 or similar on a laptop.

#

#Prerequisites:

#This script will work with one graphics card only.

#Furthermore it will only work with two CRTCs,

#i.e. two outputs may be simultaneous active.

#

#Comments:

#In order to optimize performance and minimize flicker

#xrandr is at most called twice. Once to read the current

#state and once for setting the new state. Thus, some code

#may look strange at the first glance.
