[Bug 583312] Re: Left mouse clicks not being processed


Ken Pratt, 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 (not the daily folder, but the one at the top) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. 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:

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

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:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

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

  [Dell Precision M6300] Left mouse clicks not being processed

Status in “linux” package in Ubuntu:

Bug description:
  Binary package hint: xorg

  I apologize as I can not find a set of steps to reproduce this
  problem.  It occurs often enough so that this is a major problem.  The
  scenario:  I am writing an email in evolution and all of a sudden my
  left mouse button clicks are no longer processed.  I can not select
  anything on the desktop.  I can still type, the right and middle mouse
  button still interact correctly and the keyboard interaction is
  unaffected.  This has happened several time in Evolutions as well as
  Netbeans.  It is kin to the drag and drop problem where the drag
  operation picks up something that can not be dropped.  You are left
  stuck with a mouse that is in a mode that can not be completed.

  Once I find myself in this situation (left mouse clicks no longer
  being handled by X or apps running on X), I can not restore
  functionality.  ESC does nothing.

  I also notice sometimes, especially when I am in an editor of some
  type such as G-Edit, that when I find myself in this stuck mode, the
  editor is in drag-select mode.  That is, when I move the mouse without
  any buttons pressed, the selection region in the text editor follows
  my movements as if I was holding the left mouse button down (drag
  motion).  Again, ESC does not restore functionality.  It does reset
  the selection, until I move the mouse.

  The only solution to this is to drop to console and reboot.

  This is potentially a security vulnerability.  Users that are not
  familiar with using the keyboard to get around GNOME will find
  themselves unable to minimize applications or 'lock the screen'.  This
  may leave sensitive information up on their screen.

  Thanks for the great distro and sorry I can not give you more to go
  on.  This has happened to me about 10 times since the final release.
  Fortunately, I have been using Linux since '94 (I remember the
  floppies) and have been able to recover work despite this mouse
  problem.  Others that are not so savvy, WILL loose their work.  As an
  example, if the problem chose to show itself as I type this into the
  form on the bug submission page, I would not be able to submit, nor
  would I be able recover these words...
