[Bug 1372116] Re: xorg freezes mouse and consumes cpu especially when more apps in memory

 

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://cdimage.ubuntu.com
/daily-live/current/ .

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.

Title:
  xorg freezes mouse and consumes cpu especially when more apps in
  memory

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  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.
