Try mine : www.cwwilson721.dyndns.org/slack/xorg.conf

You may have to modify the part that has the Alps Touchpad, because if you use it as-is, and don't have the driver installed, it will not start

but my video card is intel 855 GME Chipset.does it have difference from ur one i810

The 855 chipset uses the i810 driver.

now i have a refresh rate problem

thanx for help

XFree86 has an auto-config capability, where specifying "-autoconfig" or "-configure" from the command line can result in a config file being generated based on the card and display detected.

Maybe X.org has a similar function?

The XFree86 command is:

# X -autoconfig

-- or --

# X -configure

X can be replaced with "XFree86".

Peace...

xorg uses 'xorgsetup' or 'xorgconfig'
