Intel 852/855 graphics on Dell laptop

[WA9ALS - John]

Problem:  I can't get any screen resolution other than 640x480 on my Dell
laptop D500 with Intel 852/855 chipset.  It is an XGA display whose max is
1024x786 in true color in Windows.

I've downloaded the correct Linux driver (dripkg-1.0-4.i386.rpm) from Intel
and
installed it with the package manager, no errors.  However, despite
restarting X and finally rebooting, nothing seems different.  If I choose
the display with the GUI, it says 1024x768 with thousands of colors, but I
really have 640x480.

I don't completely understand the X config file, but I can edit it if I need
to and can
get some help.  Any other ideas greatly appreciated.  I have saved pertinent
posts from this list and Googled for hours, but I'm still stuck.

Thanks - John
