resolutions for intel i855GM

[davidek at ipnp.troja.mff.cuni.cz]

Hello,
   I was trying different ways of displaying OpenOffice slides
simultaneously on the projector and on LVDS. It seems the only
reasonable way is to use the "clone mode" (that works automatically
with intel driver), provided one sets up the SAME resolution for both
LVDS and VGA.

Well, here is the problem. xrandr -q gives:
Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 2048 x 2048
VGA connected (normal left inverted right)
   1280x1024      60.0 +   59.9
   1024x768       74.9     75.1     70.1     60.0     59.9
   800x600        75.0     74.9     60.3     59.9
   640x480        75.0     60.0
   720x400        70.1
LVDS connected 1400x1050+0+0 (normal left inverted right) 304mm x 228mm
   1400x1050      60.0*+
   1280x800       60.0
   1280x768       60.0
   1024x768       60.0
   800x600        60.3
   640x480        59.9
TMDS disconnected (normal left inverted right)
---------
The common mode is only 1024x768.... I wonder whether I can achieve the
mode of 1280x1024 on LVDS ?? Changing the Modes line in Screen/Display
subsection in /etc/X11/xorg.conf does not have any effect...... Is there a
way to force  intel driver to use other modes ???

Versions used:
xserver-xorg 7.2, xserver-xorg-video-intel git version of 29.8.2007.
