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? Janez -------------- next part -------------- An HTML attachment was scrubbed...

They were running an earlier version of Fedora. What we had to do was upgrade the BIOS. They are now running Fedora-11 with BIOS ver 2.6.2 Hope this helps, Tony

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
