I had Ubuntu 11.04 installed for a while and that worked fine. But when I try to boot from the Ubuntu 11.10 Live CD, the screen gets black after the purple background of what used to be the selection menu (where you could set boot options etc.). I tried to boot with
nomodeset. It then boots fine, but as soon as X needs to be started for Ubiquity to display, the screen falls to black again. With
noapic it starts almost fine (I can even hear the login sound), but still a black screen and no access to a tty.
My system specs:
Processor: AMD A4-3300M RAM: 4 GB DDR3 Video card: ATI Radeon HD 6480G
Can somebody help me?
