B R E A K T H R O U G H -- F11-on-XO1 has working video player

[Mikus Grinbergs]

Ever since mid-December 2008, none of the newer XO-1 builds (beyond
8.2.x) were able to properly show any "moving pictures" for me.

I ended up substituting another video driver in place of xv.  That gave
me a smaller picture (sometimes showing only "snapshots" rather than a
"movie").

Having applied the ticket #9590 fix (adding 'Virtual 1200 900' to the
"Screen" section of xorg.conf), I changed my os11 systems back to using
the xv video driver.  I tested under identical conditions both with and
without the #9590 fix.  That single change made the difference -- now on
my XO_1 systems, "moving pictures" work properly in F11-on-XO1 builds.

Prior to the application of the #9590 fix I could not honestly recommend
 any builds beyond 8.2.x to an XO-1 owner.   Now I can.

Mikus,

F11 is almost out of the oven!!

Thanks Mikus & everybody for all of your hard testing! Special kudos to
SMParish for doing the builds!

Here at .PY we have been able to setup the os image build machinery
(thanks Bernie!) so we plan to roll out a signed image soon.. Stay
tuned!

Any other major blocker that deserves attention?

Have the items here been resolved?

My own personal view is that the items cited are not in the 'blocker'
category.  Rather, my question is:  "Will 'fixing' be frozen once
F11-on-XO1 is made generally available, or can some items be addressed
after the initial release ?"   [I do not know the answer.]

Today I've been testing activities and collaboration. Everything feels
snappy and works decently.

The only oddity I've seen is that libertas still has some reliability
problems when automatic power management is switched on.

Libertas' PM always has been a real PITA. I heard plenty of good kernel
hackers swear between their teeth because of it. Marcelo would often
swear aloud too :-)

Today I promised to work on a cleaner patch for the main outstanding PM
issue (http://dev.laptop.org/ticket/9967), but there is certainly
something else going on. For instance, we seem to loose association for
no good reason. After a few suspend/wakeup cycles, I even managed to
make the Libertas disappear from the USB bus!

In fact, this might not even be a 2.6.31 regression. To my (somewhat
fuzzy) memory, automatic power management always has been disabled in
OLPC's official builds due to similar reliability issues.

At some point we may choose to give up trying to make libertas behave
and keep the power management feature disabled for good.

Yesterday I played a little with automatic power management on an XO-1
with build 8.2.1.

While I could not make libertas fail the same way of 2.6.31, suspend was
often making me loose association. NetworkManager did not seem to
reassociate automatically on wakeup, I had to do it manually.
