Public bug reported:
Binary package hint: xserver-xorg-video-intel
Screen rotation and video acceleration don't work together on my system.
I have a lenovo thinkpad x61 tablet (intel 965gm chipset)
In order to get rotation to work at all, I need to put "Option "DRI"
"false" in my xorg.log, which disables 3D acceleration.
Once I've done this, running "mplayer -vo sdl ~Examples/Experience\
ubuntu.ogg" (or mplayer -vo xv ...) disables rotation for the remainder
of my x session (restarting X with <ctrl-alt-backspace> usually fixes
rotation).
Running "mplayer -vo x11 -zoom" seems to work around the problem.
Something else is disabling rotation (probably firefox plugins). I just
set Option "NoAccel" "true" in xorg.conf to see if that fixes the
problem. Now, I get tearing when I drag windows around...
According to the README for the latest intel video driver, rotation
should work with 3D acceleration if the driver is built against version
1.3.0 of the server. According to xorg.log:
X Window System Version 1.3.0

I'm not sure what the deal is with the PCI:0:2:1 warning. X seems to
see two video cards on this laptop... video out works via xrandr 1.2 (I
need to use the xrandr 1.1 binary to rotate the screen. Otherwise,
fiesty's gnome crashes...)
