Freshly built Lubuntu Desktop amd64 14.10 beta 1 (20140826.1)
Hardware spec from hardinfo - https://gist.github.com/74e638f3a308f6aaef53
When using more memory on system (e.g. multiple apps or many browser tabs) the system will freeze for 10 seconds to over a minute, with the mouse cursor not moving at all, and no screen updates. When it finally responds I see cpu spikes in xorg process with lxtask showing over 100%! Shutting down applications or tabs to reduce memory load seems to make the issue go away, but trying to multitask renders system practically unusable.

Artemgy, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://
If it remains an issue, could you please run the following command in the development release from a Terminal as it will automatically gather and attach updated debug information to this report:
apport-collect -p xorg 1372116
Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.
As well, given the information from the prior release is already available, testing a release prior to the development one would not be helpful.
Thank you for your understanding.
