Comment 88 for bug 342923

What do you want them to do? Enable UXA? This was tested and resulted in many freezes, crashes and other bugs with current -intel driver. Do you really think the Ubuntu team could fix all this bugs on their own?
Intel with Exa mostly works stable in the current driver and this is the important. Who uses Linux for gaming or an Intel graphic card for 3d cad anyway? If Ubuntu had pushed the 2.6.30 Kernel release in Jaunty it would break things for many other users.

So if anybody needs the whole unleashed -intel rendering power in glxgears he could use an older release like Hardy. This is still supported and will be fine until Karmic which will most likely shipped with KMS, UXA and most likely great Intel performance (finally).
I guess for most people Intel driver is fine in Jaunty anyway even with lower glxgears performance and enabled Overlay video output. No one really needs composite to work.

It is not Ubuntus fault if -intel developers decide to dump stable and change the driver internals for two years and make them default shortly after integration.

The problem of a distribution is that most things are dependent on each other so if you decide e.g. not to upgrade X because of the problems with the newer -intel driver other graphic cards might have huge issues which are fixed in latest X. It is not easy to find a balance I guess. That's why there is LTS and a 1.5 years support for every release.

But I agree that X should have two branches, one stable and one experimental. Maybe this will happen with the stabilization of UXA and KMS but I guess they will find new fancy features to integrate and the latest driver will always need the latest X.
