I have a Sony VAIO netbook with Intel GMA-500 Poulsbo Graphics and I'm trying to boot the latest Ubuntu-12.04 Beta-2 using a bootable USB.
According to this Ubuntu-Wiki, support for Intel GMA-500 Poulsbo graphics is promising in Precise-Beta2 and should work out of the box. Of course the wiki talks about a problem when booting from USB and states that restarting X using:
sudo service lightdm restart will bring a functional graphical desktop, but nothing happens for me!
Any help is highly appreciated.
