GFX-drivers for HP Probook 4300s

view full story

http://askubuntu.com – I recently installed Ubuntu 12.10 on my HP Probook 4330s laptop and everything seems to run fine, besides the graphic card drivers. When I go into settings -> details -> graphics it says Driver: Unknown. I checked HP driver site, and it only had GFX-drivers for SuSE distros. How can I get the proper drivers for this machine?
