[sylvainsjc]

This morning i've downloaded the karmic-desktop-i386.iso Alpha 6 release

It work fine on my laptop Dell D830 and also under VirtualBox on my desktop home computer.

My desktop have jaunty release and work fine (my config is joined in attachment file) but it's impossible to launch the Alpha 6 live CD on it. The screen is systematically corrupted with vertical lines or other.
At the end I heard the ubuntu start sound but i can't see anything.
