Comment 80 for bug 201330

Ok, I read all your comments.

Now.
This bug was firstly intended to be fixed for older cards that aren't supported by fglrx or xgl and then they haven't other way to use compiz.

But then people with newer cards start adding pci id telling that ati driver was better that fglrx etc. (but also have freezes with ati driver)

Please report the problem to the origin, whitelist firstly older cards that haven't opened freeze bugs and have always worked nice with compiz.
It is safe to do this.

Then, if in the future you can add other cards (newer) known to work well with compiz or with bug that has been fixed meanwhile, more better.
