Dual GPU systems do not do well under Linux. Nvidia said they will not be supporting the technology outside of Windows so I expect you will have a lot of issues. There is a project called IronHide which attempts to accommodate it but I've not seen a success story. Maybe others can advise

oh..i uninstalled the ubuntu i had before and downloaded 12.04 again ...its working fine now...(no crossplatformui problem and no open gl problems) anyways thanks :)...it think that the integrated graphics processor in core i5 has 1.77gb graphics memory...i guess it will handle stuff
thanks
