[ubuntu-x] Confusing alpha-2 information on intel driver

[Geir Ove Myhr]

Hi everyone,

I just looked at the information page about Karmic alpha-2
(http://www.ubuntu.com/testing/karmic/alpha2) and it has a paragraph
about the UXA in the -intel driver which I find confusing:

<quote>
New Intel video driver architecture available for testing

In later Karmic milestones the Intel video driver will most probably
switch from the current "EXA" acceleration method to the new "UXA".
This will solve major performance problems of Ubuntu 9.04, but is
still not as stable as EXA, which is why it is not yet enabled by
default. We invite you to help testing UXA, please see the
instructions and feedback page.

This sounds like EXA is still the default in Karmic alpha-2, and that
UXA needs to be enabled according to the UXA testing page
(https://wiki.ubuntu.com/X/UxaTesting). But the intel driver version
in Karmic alpha-2 is 2:2.7.99.1+git20090602.ec2fde7c-0ubuntu2 [1]
which has no support for EXA anymore. Right?

[1] OT: would anybody tell me what those colons in the version numbers mean?
