Clutter 1.5.8 in rawhide

Just a quick heads up - I'm currently building Clutter 1.5.8 into

Supposedly this is 100% compatible with Clutter 1.4, but there are a lot
of internal changes in the backend parts so there's a possibility of

(I was waiting to upgrade in Rawhide until we got the necessary bugs
fixed to make it work well with GNOME Shell; 1.5.8 achieves that.)

If you run into anything, just file it in bugzilla and I'll take care of
investigating and upstreaming as necessary.

Compile with -fno-omit-frame-pointer on x86_64?

Lack of decent profiling is a major problem for making our operating
system fast. By far the most effective of profiling is sampling profile
with callgraph information.

Soeren's comment from March:

Basically summarizes the situation, and as far as I know nothing has
changed ...

Page flipping on intel (2.11 driver)

With the 2.11 update for xorg-x11-drv-intel in updates-testing we have a
couple of serious problems occurring with gnome-shell on Intel systems:

A) A complete hang where the system can't even be pinged.

B) A problem where the system continues to run fine but the GPU gets
"stuck" and no further drawing happens until the system is rebooted.

We've also had similar reports for Compiz.

These problems seem to be associated in particular with the "page
flipping" functionality that it enables.

--host=i386-redhat-linux-gnu --target=i686-redhat-linux-gnu ???

Looking at the build logs for F-12, e.g.:

<a href="" title=""></a>

we seem to have things set up to run configure as:


Which, according to my reading of the autoconf manual means:

* Build on a i386-redhat-linux-gnu
* Create code that runs on i386-redhat-linux-gnu
* Build a cross tool chain that targets i686-redhat-linux-gnu

and really doesn't make sense.

PackageKit policy: background and plans

I wanted to provide an update to the list on the current thinking about
the PackageKit policy issue from the perspective of the people working
on the core desktop packages and on the desktop user experience.

There was informal meeting earlier today with Richard Hughes, and
myself, and a couple of people who could provide help with big-picture
Fedora issues like Bill Nottingham and Jesse Keating, to try and figure
out if there were obvious steps to take in the short term.

an update to automake-1.11?

I was rather surprised to see:

<a href="" title=""></a>
<a href="" title=""></a>
<a href="" title=""></a>

Where the automake was upgraded to 1.11 for F9, F10, and F11.

In general automake hasn't had a very good track record of compatibility
between 1.x and 1.y, though this has been getting better recently.
I don't see any specific mentions of incompatible changes in a quick
scan of:

But it is also a pretty long rele
