Hi great community, I solved some problems with mi graphic card Intel GMA x3100 simply adding this PPA to my system's software sources:

ppa:glasen/intel-driver

Enter to this web page if you want more information about this PPA ;)

https://launchpad.net/~glasen/+archive/intel-driver

I had problems when i tried to open some videos in youtube; with this PPA my problem didn't appear again =P

Greetings from Chile! :D
