I have a Toshiba satellite with an AMD c-50 processor, 4 gig of ram, AMD Radeon HD 6250 Graphics. Dualboot with Win 7 64-bit, Ubuntu 11.10 64-bit.

Internet always disconnects(wired connection) after couple of minutes. Downloads and general internet use is slow.

Always a problem with my screen. It suddenly freezes and there is some moving snow(like a tv when there is no signal) with a faint background of the normal screen behind the snow! I'm a normal user, so I don't know how to use the shell to play in Ubuntu.

Win 7 use is perfect, no problems like that.

Is there someone who knows how to fix these problems?

thank you
