Dear intel-gfx developers.
After spending a huge amount of time searching for a solution for me problem
and haven't been able to find one, i decided to send a email to this mailing
list hoping someone can help me or point me on the right direction.
Hardware: Motherboard : ASRock H67M-GEProcessor: Intel Core i3 2010T AV
Receiver: Onkyo TX-NR808TV: Panasonic 50VT20
Software: Ubuntu 11.10 with xorg-edgers ppa.
Problem: When starting ubuntu without the AV receiver or the TV being on, the
xorg start with a resolution of 720x576. When turning the TV on and selecting
the AV-Receiver. The AV receiver reports that there is a signal but noting is
display on the TV, by using my receiver Display/Information menu i can see im
receiving a signal with 1920x1080i@120hz. The receiver pass's this direct to
the television and ofc since its 120hz it cant be handled. As so only a black
screen is display, not even the Onkyo GUI can be displayed.
By running the xrandr -display :0 --verbose i get:HDMI3 connected 1920x1080+0+0

There i can see that the modeline is current selected to 1920x1080@60hz. If i
select the mode as 720x576@50hz, them gnome desktop shows but its like the
screen has 2 desktops splitting the screen in half. If i move the mouse to the
top of the screen i can see it in the top and lower part of my TV. The funny
part is my TV and Receiver now report a signal of 1920x1080@50hz.
Once i change to this mode my xrandr -display :0 --verbose shows 2 new modes
that weren't there before:
Screen 0: minimum 320 x 200, current 720 x 576, maximum 8192 x 8192HDMI3

If i select for example mode 0xb9 or 0xba, i lose the image (splitted image of
gnome), and get a black screen. Once more for 50hz the AV-Receiver reports
100Hz and for 60Hz reports 120Hz.
This is like somehow the modes are being multiplied all the time by a factor of
2.
I also have tried to use i915.modeset=0 on grub. This makes Xorg fail to start
saying that no monitor was detected, then i can rmmod i915 and modprobe i915
modeset = 1, service lightdm start. And we are back again with the same
problem..
What ever if i leave my TV and Receiver ON and turn on the PC, then everything
works without a problem.
The idea is to boot ubuntu that in this case is my Home Server, and leave it
running since morning. Then when comming home the PC is already booted and into
XBMC ready for my Girlfriend to watch some TV over XBMC liveTV
>From the start i thank you for your time.--Paulo Louro
