What graphics card does the machine have? This is an Xorg problem, not a g-p-m problem.

Comment 2 Tobias F. 2010-04-19 15:14:06 UTC
It is a Pine-Trail Netbook, so it has the same Graphic Card as all other netbooks, using the N450 processor.

Comment 3 Tobias F. 2010-04-19 15:17:35 UTC
The graphic card is called: GMA 3100
