Spoke with cjwatson on IRC, he'll take it from here; he's about to roll
a new ubiquity upload with this.

The easiest way to prove it's something in the panel leaking would be to
kill the panel as soon as the session starts (or remove the binary in an
early command temporarily).

And actually glancing at the code, perhaps the leak is a little bit
further up. I don't see any calls to unreference the memory of the
pixmap allocation after setting it after each expose event. Here's
another patch that might help address this.
** Attachment added: patch
I'm building an image for testing of Bryce's fix. In the meanwhile, I
did some quick testing using Mario's suggestions.
Like Robert did, I just let the Thinkpad X201 sit there while monitoring
processes and Xorg.0.log. Sure enough, the panel process starts using up
the CPU, going up to about 80%,

Xorg segfaults during LiveCD installation using preseed file
I built an image based on latest Natty daily and incorporating Bryce's
fixed ubiquity. It looks promising, already the panel is no longer
misbehaving and it doesn't consume CPU like it used to. I was able to
complete the installation process on the X201 where the failure was so
easily reproduced
Hi All,
I used the Natty daily with Bryce's fix for ubiquity on our test
machines, I'm glad to report that none of them dropped to LiveCD
environment or rebooted. The vast majority completed the installation
process correctly, the few that failed did so for unrelated reasons.
This comprises about
Hi Daniel,
So this is my take on the issue based on your results :
1) the function call commented out by Bryces patch fixes on_expose from
being called continuously. That function creates a new expose event making
on_expose call again.
2) the above causes the high cpu regardless of memory leak
If you can modify the installer image, please get a crashdump from X by
adding '-core' to it's cmdline options (wherever those are set).
Upstream isn't totally convinced this is a driver bug, but that the X
client (=installer) is leaking memory. Please get a dump of 'cat

Fwiw, we've been getting these out-of-memory-leading-to-X-crash bugs for
about a month. The first reported bug I can recall was Mario's bug
#705078 dated 2011-01-19.
I see ubiquity 2.5.6 was uploaded on 2011-01-17. If it is an X client
leaking and we think the installer is a suspect, then the
This crash is now happening for us pretty reliably even without our test
configuration, i.e. with a pristine image. Bug 720235 details one of
the look ma, no hands crashes we had, and I just had another one with
the latest (today) desktop image.

Not sure how I associated with 2.5.6 with 1/17. But 2.5.9 (rev 380) on

Here are the backtraces from the systems where I experienced this crash,
I realize they aren't 100% identical. Our installation procedure is very
homogeneous so I think these might all be related, as they all occured
using the same installation procedure.

Hi Daniel, for the crash we really gotta have a full backtrace, either
via apport automatically or by hand via gdb.
Some directions are available at http://wiki.ubuntu.com/X/Backtracing
The crash (this one and the ones experienced previously) are due to
programming errors in how X handles out of
