I dunno :(
Those are the exact steps I took with the Karmic live disk (minus trying the
alt-shift-f12), and have taken
since it's alpha stages. I even booted to that disk to make sure I was
correct, though I usually just go straight to the installation from the boot
menu or the install icon on the desktop - but as I already know about the
graphics corruption, and how to fix it, I don't play with the live desktop
session at all as the 'anomalies' do not effect the install process.
