Hi,
(Firstly, I've just now joined the xorg list, so I couldn't see the CCs from
the archived copy of the announcement, and I duly apologise if I've dropped
CCs..)
I have a problem with the xf86-video-intel-2.0.0 driver (hand built) running
under Debian unstable (Xorg server 1.3.0). The machine is a Core 2 generation
Macbook with what I believe is GMA 950 video.
Normally, the driver works fine. But I've recently been trying to set up
multiple monitors (laptop panel + VGA display) without success. Merged/clone,
it seems to work fine, but if I try to enable the Xinerama extension, the
server crashes.

"xorg.conf" is my current, working config. With this config, I
get "Xorg.0.log-good" from the server. Uncommenting this line:
# Option "Xinerama"
Is enough to give me the crash, and the resulting "Xorg.0.log-bad".
It's obviously possible that my config is somehow incorrect, but it looks more
likely that this is a bug in the intel video driver:
(II) intel(0): direct rendering: Failed
(II) intel(0): RandR 1.2 enabled, ignore the following RandR disabled message.
