Actually, my Xorg experience upgrading from FC6 to FC7 is exactly the same as Jeremie's. I even
raised this Fedora bug about it:

Interesting - I shall try this.

I tried using XOrg 7.2 with a compositing manager and EXA, and the result was so slow as to be

Isn't XAA the "old" acceleration architecture that EXA is supposed to replace, though?
