Public bug reported:
I have a Llano system (CPU is AMD A8-3850, Motherboard is ASRock A75M HVS)
with onboard amd graphics. (I wouldn't recommend using the stock cpu fan,
btw, as it's very noisy.)
In ubuntu 11.10, the system works fine; my notes from back then say
"Ubuntu 11.04 32 bits installed without a hitch, though I did have to download
the latest Catalyst driver straight from AMD."
(I may have installed with the alternate cd.) So the hardware is ok.
The Ubuntu 12.04 alpha 1 live dvd boots, shows the initial splash screen (the
little icons for human and keyboard),
then blanks the screen and shows the cursor blinking in the upper left for a
second or two as normal,
but then the monitor says "no signal".
Control-alt-F1 at this point gets you to a console login sometimes
(sometimes the video mode is crazy and the monitor can't handle it).
Plugging in an nvidia card does let install proceed, but does not yield working
video.
Installing the latest ATI catalyst drivers from AMD fails, doesn't install
aticonfig.
So, I'm foobar'd. No video with builtin Llano amd graphics; no video
with nvidia geforce 8500 GT card.
