Thinkpad T42, unity give only black screen

[EricDHH]

Binary package hint: unity

DISTRIB_RELEASE=10.10
DISTRIB_CODENAME=maverick
DISTRIB_DESCRIPTION="Ubuntu maverick (development branch)"

Just updated to 10.10. and tryin to use unity on the thinkpad t42, The normal gnome desktop works well, the unr 2d comes up with ugly fat font and icons painted over another. The unr profile dims out gdm, turns black and give me a pointer. Nothing else than a solid black screen, no funcion in corners, no panels, no alt-f2 works there. Switching to another console is not working at this point.

The issues comes from the ATI driver which doesn't support all the effects unity uses. I'm marking as a duplicate of the master bug for it.
