xorg.conf for dual monitor setup

[Louis Turk]

Hi everyone,

What is wrong with the following xorg.conf file that it won't use the
second monitor? The second monitor in fact goes into power saving mode
the instant X starts. The graphic card is HIS Radeon HD 6450, running on
latest 64 bit Archlinux.
