f18-64: Video Resolution problem on a netbook ASUS 1225C-GRY015U

[Dario Lesca]

Hi, I have buy this Asus netbook with Ubuntu pre-installed:

ASUS 1225C-GRY015U
http://www.monclick.it/schede/asus/1225C-GRY015U/1225c-gry015u.htm

With a Video integrate VGA compatible controller Intel Corporation Atom
Processor D2xxx/N2xxx Integrated Graphics Controller (rev 09) and driver
gma500

(see below lspci and lshw)

At the first power on, I do not have start Ubuntu, then do not know if
the problem (see below) there is with Ubuntu, but I have install
straightaway Fedora 18 64 bit.

After install and update f18 (kernel 3.8.2-206.fc18.x86_64), I have try
to work into Gnome 3.6, but the video performance are very slow and
gnome-shell use too many CPU :

Furthermore, the video resolution is fixed to 1366x768 (16:9) and when I
attach a video projector (this is very important for me) with a 1024x768
resolution It's not possible to clone the monitors and see what what I'm
projecting. Switch via Fn+monitor I can only see netbook monitor or
projector...  

Question: there is some way to resolve the high CPU usage of gnome-shell
and change the video resolution when projector is connect?

Many thanks.
