Comment 103 for bug 201330

I want to add this argument : When blacklisting all cards, we lose knowledge about the real bugs and we don't help fixing them. I have a ATI mobility radeon x300. Do we know if that card works? No. Why? Because it is blacklisted. In reality, this card *had* problems with very initial versions of compiz and ati in ubuntu (feisty?), but since Gutsy, ati drivers and compiz works very well, and it is far more stable than fglrx which is currently the worst graphic driver that I know. Now we're in Hardy and soon intrepid. We're far away from ati and compiz versions shipped in feisty.

I think that massive blacklisting is a short term workaround, but it have a long term negative impact and it is not a valuable solution. I might be wrong about the real quantity of ATI cards which really have problems, but it looks to me that only some specific cards really have problems (like Xpress 200, bug #197135).

Having compiz disabled by default for ATI cards except the special ones which are confirmed to have serious problems would sound correct to me, but not a black list which prevent compiz to be enabled on all ATI cards for people who wants to try it.
