lspci output

I use a netbook with Intel GMA 3150. When I connect Samsung SyncMaster B2430 monitor to the netbook it setup bad resolution. Maximum availabled resolution is 1024x768 but in really the monitor works with 1920x1080.

I've setuped such resolution with xrandr --newmode it's work fine. But I want to autodetect of all supported resolutions.

I don't follow.  Where are you looking that "maximum available resolution" is 1024x768?  Your X log certainly sees 1920x1080 modes.

Can you attach the output of xrandr --verbose ?

First when I connected my monitor in first time I got 1024x768 resoulution. 
I coulnd't choose resolution more than 1024x768. It's mean that xrandr shows maximum 1024x768.
Then I use cvt and xrandr to setup new resoulution. So I got 1920x1080.
Now when i'm doing xrandr i get many new resoulutions which i didn't see before. It's weird for me. I will tried it from live usb. Maybe i can reproduce it.

I loaded Fedora 17 Gnome LiveCD. connect my DNS G236 monitor and got a wrong picture on both monitor and netbook displays.

Yeah, sorry, your GPU is lame.  It can't draw 3d to surfaces that are more than 2048 wide.  See the duplicate bug for details.
