Call for testing: X.org server update [URGENT]

[Martin Pitt]

Hello fellow developers,

On April 15, a major memory leak was introduced into the X.org server
which causes the computer to get slower and slower over some hours,
and finally becoming totally sluggish. This is tracked in
https://launchpad.net/bugs/565981 .

Thanks to the tireless investigations of Robert Hooker and Tormod
Volden, this was tracked down to a recently added patch which fixed
some crashes intoduced by the GLX 1.4 enablement patches. A first
attempt to fixing the memory problem wasn't successful unfortunately,
and isn't easy.

The safest solution right now is to roll back all three patches. This
will fix both the memory leak and thus the performance problem, as
well as avoid the X crashes which were introduced by the GLX 1.4
enabling.  While we had this combination before, we haven't tested it
with the current lucid userspace, and thus we need some extensive
tests on various hardware to get more data about it.

I set up a wiki page to explain how to install the proposed packages
and for adding feedback:

  https://wiki.ubuntu.com/X/Testing/GEMLeak

On Friday we will check how much and which kind of feedback we got,
and depending on that will decide about the risk of putting it into
Lucid final, or doing an early SRU. (We need testing feedback in
either case, of course).

Thank you in advance for helping with testing!

Martin
