["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Karl Fogel, 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
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily kernel folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11.1

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  mouse usage causes Xorg CPU usage to spike, and mouse pointer becomes
  less responsive

Status in “linux” package in Ubuntu:
  Incomplete
Status in “linux” source package in Lucid:
  Triaged
Status in “xserver-xorg-video-nouveau” package in Fedora:
  Unknown

Bug description:
  Binary package hint: xorg

  Over time, my mouse pointer becomes more and more erratic and
  unresponsive.  It never becomes unusable, but it gets jerky and hard
  to use.  If I run 'top', I can watch Xorg CPU usage spike in direct
  correlation to how much I move the mouse around (and the mouse
  performance gets worse while I'm doing this).  If I wave the mouse
  pointer around a lot, CPU will reliably hit 100%, and the pointer will
  be far behind my physical gestures with the mouse (and will continue
  to move for a while after I stop moving the mouse).  CPU climbs back
  down after I stop moving the mouse.

  When I first log in, everything is fine.  This problem gets worse the
  longer I stay in the same X Session.  I haven't tried logging out back
  to GDM and logging back in; if you need me to I can try that.

  Switching between windows / desktops is also increasingly sluggish.

  This is all on  Ubuntu lucid (development branch).

  I don't know if this is related to any of these bugs:
