Open-Source Radeon 2D Performance Is Better With Ubuntu 14.10

Mode-setting, yes. But GLAMOR (2D) acceleration depends on 3D acceleration.

Doh, yes, of course. Didn't think that far.

So is this performance change predominantly a result of the mesa version bumping from 10.1.3 to 10.3?

No, it's mostly the X upgrade. Glamor went through a bunch of optimizations.

The Mesa upgrade surely helped a bit too, though.

Hmm... X upgrade is too complicated to implement without doing a full distro upgrade. The 2d on F20 for AMD-7770K is marginally painful when dealing with a full load of business applications spread across a pair of 1920x1200's. Guess I'll wait on F21 and see how that improves the situation.
