Screen shows corruption on LiveCD/installer

[Mathieu Trudel-Lapierre]

When booting from the liveCD and choosing "Install Ubuntu"; the screen loads first with a corrupted splash, then with large squares/corruption for the X screen.

When choosing "Try Ubuntu" instead, the splash screen is still corrupted but Unity starts properly.

I've had a check with the kernel team, they think it is a dupe of a bug now marked with a 'fix comitted'.
