I guess this is similar to bug 9264 http://defect.opensolaris.org/bz/show_bug.cgi?id=9264#c4
In Xorg.0.log, what "Output" devices are connected and which ones are connected to "Pipe A" and "Pipe B"? I guess it has recognized an "LVDS" output (although no internal LVDS panel is present); and the workaround is to disable the LVDS output - see comment 4 on the above bug. -- This message posted from opensolaris.org
