Disabling internal laptop LCD, enabling external monitor.

[Dreamlocked]

Hello,

My laptop's internal Monitor isn't working so well (hardware failure) but it still lights up and gets filled with artifacts.
I would like to know what xorg.conf option I should add in order to disable it completely, and only enable the external monitor.

Hardware : ATI Radeon 9100
Driver : the open source radeon driver that comes with Xubuntu Hardy (6.8.0)

Thank you in advance.

See "xorg.conf based configuration" on http://wiki.debian.org/XStrikeForce/HowToRandR12

Thanks, nice article.
Also found out that I can add

xrandr --output LVDS --off

as a startup command
