About comments 69,70,71 of mine, I have to report that having a dual system
with windows7 I tried to login there and faced the same problem. After 2 days
of trying to enter to stable intel graphics i am at a situation where as soon
as windows discover my mobile HD 5470 they give me a black screen. So it is
very possible i have a hardware failure even if i didnt used radeon much.
Sorry for bothering you by my last comments.
