[Bug 1043518] Re: live cd is unusable due to video degradation with the splash boot option enabled

[Rrrrube]

I've got this problem too. I have an AMD processor and a GeForce GTX
460. I'd downloaded QQ beta last week but couldn't get it to boot. Tried
again today with the latest daily build, but I have the same problem.

I get the initial purple screen with the accessibility options (at
least, I think that's what the screen is!) Then it goes onto the screen
with the Ubuntu name and the orange dots. The word Ubuntu is completely
garbled and unreadable, so the graphics problem has already kicked in.
Then it changes onto a mostly black screen with lots of little icons and
random garbage spread all over the place. I can't move the mouse and it
doesn't seem to respond to any keystrokes I tried. I can't get any kind
of log reports because nothing works. I have to hit the reset button and
restart my computer because it's completely frozen.

I haven't tried the Nomodeset option yet but I wanted to report this
bug, because it's a pretty big deal breaker for the average person if
they're faced with the same result I got.
