i have a macbook, whos resolution is 1280x800 and i want to use another monitor (1280x1024) as second screen. not mirror display, but just to have two desktops. back when i used osx it worked great, i just had to plug it in. with fedora 6 and now 7 i cant get it to work. ive tried around in the dual head section in the system configuration and also tried to edit xorg.conf manually, but it wont work with any configuration. has any1 a running system with a similar config or an idea of how to get it working????
