Problem with latest intel driver on 965GM

[Nicolas Bougues]

Dear list,

I'm using a brand new Dell D630 which features the 965GM video chipset with a 
1440x900 LCD panel, and having some resolution trouble with it.

Using VESA driver (and with the the help of the 915resolution tool!) it does 
the native resolution well.

OTOH, with the latest (as of monday) intel driver pulled from git, the screen 
resolution seems to be limited to 1280x800, no matter what I can put in the 
xorg.conf file. xrandr will report the 1440x900 mode as available, but when I 
switch to it, the display gets very blurry, although X is really using 
1440x900. Just like if I were exceeding the hardware resolution, when I'm 
not.

From my point of view, it's somewhat like if X was sending 1440x900, but the 
LVDS driver was set up for 1280x800, would resample to that resolution, and 
then stretching to 1440x900 of the panel.

I'm not sure whether I got something wrong with the xorg.conf files (I tried 
too many options to mention, but came back to something simple), or if there 
is a slight glitch in the driver somewhere.

I attached my xorg.conf and server logfile.

Maybe there is something worong with the build too. I'm using Ubuntu 7.04.
Note that I had to do the following patch in order to have the compilation 
succeed :
diff -ur xorg-server-1.3.0.0/hw/xfree86/modes/xf86Crtc.c 
xorg-server-1.3.0.0.new/hw/xfree86/modes/xf86Crtc.c

Thanks in advance for any help.
