Bug Description

When I start the machine I get to the login screen except that it is black but the mouse shows that there is a text field in the middle of the screen. If I go to a terminal and I'll be back in the GUI, I have no mouse interface is frozen and I see letters and numbers on a purple background in a very basic resolution.

for some reason the radeon drm module isn't loaded, which would provide proper modesetting

Even after having mounted the drm and radeon modules, I still have a black screen at the login screen, and a resolution unreadable "multicolored" after the connection. where it could come from?

Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of the introduction of a regression, and when this regression was introduced.

not directly after installation, first start.
everything is in the bug report, I think ...
I did 2 times, installation, and it happened the same thing.
perhaps are there other interesting file to display ...

Do you happen to know if this issue also happens in Quantal or other earlier releases?

This is the first version I install on ppc, I do not know if this happens with another version. I'll try with Quantal when I'm back home next week.

same problem in ubuntu 12.10, in netboot installation.

if I recompile the kernel, there is a chance that everything is working properly?
