Using External LCD with Docking Station FC6


Hi,

I have a Dell D600 laptop with ATI Radeon 9000 (R250 chipset). I have installed the latest (well meaning, the last version which was released last yr to ahve support for the 9000) from ATI

Using kernel 2.6.19-1.2911.fc6 (I *think* this is the latest Fedora core, but they change everyday...) and Xorg 7.1

My laptop lcd support upto 1024x768 and i get this with no issues. However, when i boot up my machine with laptop docked i get a black screen both on my external LCD as well as on my laptop (once i undock it). I have been playing around with this i.e. making changes to xorg.conf , and i do remember a time when i did get display on my lcd but it wasnt at my expected 1280x1024 resolution, but i cant tell for sure if fglrx was loaded at that time or not. At one point i also used the "System->Preferences" option which might explain an extra screen & device section in there....

I am hoping someone out there may have a similar configuration and can help me out, i just spent too much time on this now. [Note, some input device sections are truncated for brevity]

And i really appreciate any help or insights you guys might have. Is there anything i need to do in particular to make sure my computer is properly docked...i.e. recognized by linux??

Here's my xorg.conf
