Yes, I know this, but thanks for the reminder. The gma500 driver as I intend to use it looks good enough though.

There are two cameras, one front one rear.

AFAIK there is no built in mouse, I attach a USB one to get a pointing device.

Alright! Thank you very much for your valuable input and the time taken.
I still have the SFR linux iso, maybe reinstalling the working OS could help me. I'll need more room, so buy a micro-SD card to host both systems :)
