If you want the vga port to be primary add the option "MonitorLayout" "CRT, LVDS" to you xf86config file. that will tell the board to use the crt port with he primary crtc (normally on notebooks, the primary crtc drives the LCD panel). > > Can I even do analog out and use the builtin display dual head?

Yeah, you have two options. you can use xinerama and specify two separate screen, device, and monitor sections in your XF86Config and create a screenlayout with both heads. see this example: http://eight.dhs.org/files/XF86Config-4.xinerama the other option is mergedfb, which rather than have two separate framebuffers and viewports connected using xinerama, creates one large framebuffer with two viewports looking into it. this allow things like DRI to work on both heads. http://www.botchco.com/alex/radeon/mergedfb/ > > The strange thing is I *think* I had this working before with X 4.2. > I > upgraded to 4.3 from rawhide source to try and get DVI to work better > which it did but still I couldn't get rid of some distortion. > You might have. the options for the radeon driver have changed alot between 4.2.0 -> 4.3.0 -> current cvs/rawhide. In the past you had to specify option "crtscreen" to force the vga port I think. current CVS uses the monitorlayout option to change how your heads are configured.
