Yep, you're definitely running radeon. Unless you picked up a KMS driver stack from Fedora (which seems unlikely given the version numbers) I don't have a good explanation for why you are getting RDR, but I guess it's a good problem to have. Don't touch anything on that system

I did compile a KMS stack, but I changed back because of instabilities.
But I'm sure I'm using the normal stack now, pacman (the package manager of ArchLinux) would have warned me if I didn't.
So, for those who haven't my chance, I can assure you it is AWESOME !
My glxgears in action, RDR but not tear-free:
How on earth did you make that picture?

I have no clues why the background is transparent though.
Tearing is an effect of the monitor. It never shows in screenshots, only with pictures taken with a camera... :P Why is it showing on your screenshot?
Are you sure that tearing is an effect of the monitor ?
I thought it had to see with changing the front buffer while updating the screen. I didn't activate V-Sync (I should start looking for it).
Whatever, it has always been this way with the radeon driver on my laptop. Usually, you can barely see it but it is quite visible with glxgears. I guess it is because it is not really accelerated (look at the poor FPS rate, and a core of my CPU is fully used).
When you add a compositor into the mix, you can get tearing at the compositor level as well and that *does* show up in screen shots.
Didn't think of that.
So in other words, we're screwed double
Thanks for the explanation. Wayland is surely a good project, I can't wait to find an Intel GPU to try it out.
