Hi,
we have some old dell optiplex 745 machines which have the Intel 965q
chipset. The problem is, that they freeze as soon as the system tries to
start the X system. It happens even before any log is written. This
happens almost every time (for some reason it sometimes work, but 99% it
fails). When i change the graphic driver in xorg.conf from intel to vesa
it mostly works, but still i sometimes get a flickering screen, but this
can mostly be resolved using ctrl+alt+backspace (sometimes you have to
try this twice). We use the 1024x768 and 24 bit colors, so this
shouldn't be the problem. 

Does anyone know a fix for this problem?

______________________________________________________

This is an issue with the graphics, it gets initialized in the wrong way
( driver ) The installer does not recognize the correct video chip
during install.
If you boot the system in runlevel 3 and then change the driver to i810
in the device section of /etc/X11/xorg.conf :

Section "Device"
        Identifier  "Videocard0"
        Driver      "i810"
EndSection

Good luck,
Edwin
