Comment 26 for bug 288807

I've solved bug #532579 "Segfault in libint10 when restarting xserver or using xorg.conf" - the vesa module is needed to check the VBE VESA settings.

This enhanced xorg.conf provides the workaround for full 1024x768 on Lucid:

----- /etc/X11/xorg.conf -----
Section "Module"
 Load "vesa"
EndSection

Section "Device"
 Identifier "Intel Corporation 82815 CGC"
 Driver "intel"

 Option "DPMS"

EndSection

 Device "Intel Corporation 82815 CGC"
