What is your graphics card vendor first?

What is your hardware setup? There is a "S-video" marked as connected in addition to the VGA. It has the two resolutions you can see. Do you have two monitors or one monitor connected two ways?

What happens if you execute

xrandr --output VGA-0 --primary

If you are confident that your VGA connection is working properly, you could also try to run

xrandr --output S-video --off
although you might run the risk to end up with a dark screen.

My videocard have 2 outputs VGA and DVI. I have one monitor connected to VGA.

xrandr --output VGA-0 --primaryI don`t see any changes after executing this code

Now I use Karmic Koala live cd until problem is solved, i see that Karmic koala show my monitor as AG Neovo '17' but Lucid Lynx show 'Mirror Screens' :confused:
