           Summary: no output on LVDS if booting with external VGA connected
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org

This is a laptop with X700 Mobility (rv410). If I boot, then plug in the
external VGA monitor, everything is fine and I can play with dual-screen. But
if I boot with the external screen connected, the BIOS uses it for primary
display and there's nothing on the LVDS. Then when X starts, I get the
colourful slow "blooming" effect on the LVDS, which I once was explained
happens when the output is enabled but the crtc is not on(?). Changing VT or
restarting X does not help.

Tested with latest git, on xserver 1.5.2 (Ubuntu 8.10 Beta). (Will attach logs,
just need to find them)
