Install on entire disk The lubuntu 326 amd64 daily desktop amd64 iso for vivid on a kvm guest with qxl graphics. Then login at lightdm into the lubuntu session. Xorg will crash. It does this everytime I login but I had to add the gnome polickit bakcend to autostart so I could allow apport to prompt for password for system information otherwise it will keep trying to send but Description: Ubuntu Vivid Vervet (development branch)
