what should be the resolution of that display?
if you use kde then first set it on configure your computer/hardware/configure video card/resolution
what options are given there?
if the option you want is there, select it and then go to configure your desktop/hardware/display and monitor/size and orientation and select it from that list
the driver for that video card should be already loaded since intel provides them and are already present in every kernel pclinux uses afik
