Whole desktop becomes very slow, replacing compiz with metacity fixes the problem

[Morten Justesen]

Binary package hint: compiz

After using the system for some time, the whole desktop becomes unresponsive, and there are rendering artifacts where trying to open any of the menus (trying to use anything really).

The problem appears to be random. I believe the problem is with compiz as replacing it with metacity removed the problem.

I can confirm also that my desktop is very unresponsive with the latest ubuntu release 10.04. The issue seems to happen randomly and can be present right after boot-up or later. Since there are times when everything works responsive, I do not blame my processors performance capability.

It helped to switch the appearance preferences to None instead of Normal, but I do not yet have long term experience with that workaround.

I think I've found the culprit, disabling Kernel mode-setting solved the problem. I have confirmed this on two machines now. It's more likely a bug in the driver than a problem with compiz. KMS can be turned off using this guide: https://wiki.ubuntu.com/X/KernelModeSetting.

Thanks for the report, it has been some time without any response or feedback in this bug report and we are wondering if this is still an issue for you with the latest release of Ubuntu the Natty Narwhal, May you please test with that version and comment back if you're still having or not the issue? Please have a look at http://www.ubuntu.com/download to know how to install that version.Thanks in advance and sorry for the late response.
