>   Being curious about Maverick, I went to cdimage.ubuntu.com and downloaded the daily live CD. When booting it, I got nothing but a white underscore that would stay there forever. I then tried to go through the options at F6 and detected that with acpi=off parameter, it would boot just fine. The white underscore appears to appear before Plymouth. This may suggest that there is a driver issue with radeon? Or KMS or the Kernel? Hardware issue can be excluded, I guess, since Lucid, which I am writing this on, works just fine.
