I've got a Dell Latitude D620, dell docking station and a Dell 2007WFP (20" widescreen lcd). With XP I had the laptop screen and the lcd working as dual screens. But for the life of me I cannot get CentOS5 to work with dual screens. Anyone have this working? I would greatly appreciate any assistance.
I have a similar setup with RHEL 5 desktop .. with the nvidia card and I had to use the nvidia driver to make it work.
