Wondering if it is scheduled yet. I have same issue:

 Check the 72%CPU usage above. It may have something to do with suspend/unsuspend back and forth.

After reboot system behaves fine, but slowly degrades with Xorg cosuming more and and more CPU

ill, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect 1141064

I get a popup that says no additional information could be collected.

That version is no more supported; please open a new bug report if the actual archive found version also has the same issue.
