Thanks for posting this bug report to help make Ubuntu better.

Which version of Ubuntu are you running?

In addition to the information you provided, could you also provide the following as separate attachments?

~/.xsession-errors file
 /var/log/Xorg.0.log
 the output of lspci -vvnn

Also, see if this bug persists with the default settings. To restore defaults, launch compiz-config-manager in it and then go to "Preferences" (left bottom corner) and click on the "Reset to defaults" button. Post your memory usage with these default settings.

This information will help solve this problem.

[Amit Kucheria (amitk)]

I am running Hardy updated on a weekly basis. I'll revert to defaults and report back ASAP.

Requested files attached.

[jlparise (jlparise)]

Thanks for uploading those files.

Once you have reverted to the defaults and posted the results we will be able to change the status of this bug.

[Craig Magina (craig.magina)]

I would also like to add Ubuntu 7.10 with default settings as having this issue as well. The compiz.real thread was eatting ~50% of 512MB of ram. It is a recent install, default "Normal" 3D settings, fully updated from the default repositories (did not enable backports or pre-release). I will attach the same files as requested above. The system has an uptime of:
11:38:57 up 1 day, 20:18, 2 users, load average: 1.01, 0.99, 0.60
Basically, it hasn't been shutdown since the install/update finished and has been idle for ~36 hours. I noticed the massive memory usage due to the system monitor in my bar, seeing the swap space near fully used. Top revealed the culprit as compiz.real.

[Craig Magina (craig.magina)]

I forgot to mention another difference being my machine is a 32-bit machine.

Linux falmar 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008 i686 GNU/Linux

[jlparise (jlparise)]

Thanks for the updates and information!

I've changed Status to confirmed. There seems to be enough information for the developers here.

Craig Magina also confirmed he has the same problem.

If either of you get any more information abotu this bug please add it here.

Craig, which version of Ubuntu are you running?

[Craig Magina (craig.magina)]

Ubuntu 7.10 32-bit
Fully updated from the default repositories.

[jlparise (jlparise)]

Thanks for providing that info. I've marked this bug as confirmed I believe it has enough information to be diagnosed/fixed.

Please continue to add any additional relevant information.

[Amit Kucheria (amitk)]

Previous attachment is messed up. New one attached below

[jlparise (jlparise)]

Thanks for the additional information. This looks like a pretty complete bug report now. If you find any other information you think would be helpful please add it.

[Michael Vogt (mvo)]

If its still reproducable upstream would be interessted in the output of xrestop

[Mosh (iain-moshville)]

I'm getting the exact same issue on 9.04. I'll attach the files requested above. If there's anything else I can upload, please ask. It's making system response sporadically *awful*.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner. There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test it on a currently supported Ubuntu version. When you test it and it is still an issue, kindly upload the updated logs by running apport-collect <bug #> and any other logs that are relevant for this particular issue.
