It works great in opensuse 11.1 amd64/kde 4.2.1, and not so great in kubuntu 8.10 32b (kde4.2x) on the same hw (x2 4850e/2G/9550-128MB); if I enable effects it is unusably slow on kubuntu (otherwise it works as good as whatever fglrx was in the 'buntu repos). I'm not sure whether its compiz or kwin in both/either distro though, and I did spend a little more time and attention on tweaks for suse.
Phoronix: AMD Catalyst 9.3 Brings OpenGL Composite Support
While the Catalyst driver for Windows was released a number of days ago, the Catalyst Linux driver was missing. It has, however, been released today. AMD's Linux engineers ended up delaying the Catalyst 9.3 release so they could spend additional time tuning this driver, since it will be the last release that supports the R300 through R500 series as the support is being dropped. The significant feature that was pushed back into the Catalyst 9.3 Linux driver is improved Composite support.
"since it will be the last release that supports the R300 through R500 series as the support is being dropped"
I think that they should have said:
"since it will be the last release that supports the R300 through R500 series as the support is being dropped, most of the newer features like the improved Composite support will not be available on these cards"
Just tell me, how long will it last before that that stuff is going to work? There are so much dependencies. DRI2, Mesa, GEM/TT, rdr, etc.
My best guess that it will not work before Fedora 12 or even beyond that.
Do we really have to wait for another year?
I guess it depends on what you mean by "work". All of the dependencies are in F11 today. The integrated set of drivers is only *just* in, of course -- radeon-rewrite was the last piece to go in and it's very new -- but I believe all the pieces are there.
The coding and integration are basically done and what's left is testing, bug fixing and performance tuning. You won't see it in an enterprise distro for a year but AFAIK the intent is for it to be useable in F11 (whereas in F10 it was more of a technology demonstrator).
I imagine the live CD is still up from a couple of days ago (second link above). I'll be trying it out on Monday and if you might want to do the same. If you have problems with it please sing out and file or update bugs. AFAIK the drivers are at the "works on the devs systems, now to make sure it works on everyone else's system too" point.
