Onboard video is improving, an Intel 945 is supposed to be good, but 
Intel 7xxs leave something to be desired.

IAC, You need to enable support for it.  If it worked OK before and now 
doesn't, there is probably a configuration issue.

You need, in the X configuration file:

     	Load       "glx"
     	Load       "dri"

      *     *     *

      Section "Device"
     	Identifier  	"<whatever>"
     	Driver      	"<driver_name>"

You *must* have the <driver_name> correct.  Do you know which 
NorthBridge chip your MotherBoard is using?

You need Mesa that is built with: DRI

You need a Kernel with the needed DRM driver for your chip and if this 
is a module, you need to be sure that it gets installed.

I also had to change my BIOS setup, but that was probably because I had 
previously changed it.  If you never touched it, it should be OK.

Leave your X session, login on a Console as root and:

	killall kdm

then logout and log back in as your user account.  Run this:

	startx > my_X.log 2>&1

and read the log.

Look for error messages.
