I have had this same problem with my laptop.  Reading through
/var/log/Xorg.0.log you'll probably find that the 1024x768 LCD is
found but that the hsync and vsync are not correctly detected.
Try looking for specs for your particular laptop and adding them to
/etc/X11/xorg.conf, or you can try adding the same as mine:

Section "Monitor"
	Identifier	"Configured Monitor"
	Horizsync		31.5-48.0
	Vertrefresh	56.0-65.0
