When attempting to run the ubuntu 11.04 live CD on my wife's laptop, I consistently get a black screen with multicolored vertical bars - no video.
This happens only when using kernel mode setting. When i boot with modesetting off, it boots without problems. However, I'm not really interested in using natty in fallback mode, and would like to try out the 3d accelerated version. I believe that it should be supported on my hardware (Radeon RS482 - Radeon Xpress 200M).
Is this just a bug for which there is currently no fix, or is there some workaround for it?
Update: This also happens with the latest 11.10 beta1.
