Eric, any idea?
Comment 3 liuhaien 2008-09-17 23:06:05 UTC 
this issue also happens with xf86-video-intel-2.5-branch.
Comment 4 liuhaien 2008-09-18 02:00:15 UTC 
we can walk around this issue by using option "--disable-dri2" on building xserver.
Comment 5 Gordon Jin 2008-09-19 01:10:56 UTC 
How about if removing /opt/X11R7/lib/xorg/modules/extensions/libdri2.so?

yes, if removing /opt/X11R7/lib/xorg/modules/extensions/libdri2.so and libdri2.la, X can start up normally.

So it's environment mess issue.
