Description of problem:
Using FC3 on an IBM R40 laptop with Radeon Mobility M6 graphics chip,
with external monitor attached. The move from xorg 6.7 to 6.8 has
broken the detection of the laptop panel as the primary display for
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Install FC2 and configure for dual-head
2.Upgrade to FC3 (OR just install Xorg 6.8 from CVS head)
3.Test dual-head (is broken)
Actual Results: Desktop only gets drawn on the external monitor, and
the laptop panel turns off.
Expected Results: The desktop should span both the laptop panel and
the external monitor.
This is an upstream bug specifically in the Xorg 6.8 server. It is
not present in Xorg 6.7. If you copy back the ati_drv.o and
radeon_drv.o files from 6.7 after installing 6.8 the problem goes
away. I'm marking this as high as this is a regression and will be a
showstopper for many people.
