i'm having some troubles with screen resolution.
First of all, i'm using a Lenovo Thinkpad E520, with BackTrack 5 R2 installed.
As far as I know, BT is based on Ubuntu 3.2, so I hope this is the right place to ask for help.

My natural resolution is 1366x768, but I'm stuck with 1024x768.
This is my hardware:

lspci | grep VGA
00:02.0 VGA compatible controller: Interl Corporation 2nd Generation Core 
Processor Family Integrated Graphics Controller (rev 09)

How can I fix that?
Is there a ready-to-use driver or I have to compile that from source?
At least, is there a solution, at all? :(
