[Bug 1340466] Re: clicking on launcher trashes screen and hangs system

 

cedial, 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 REPLACE-WITH-BUG-NUMBER

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:
  clicking on launcher trashes screen and hangs system

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  clicking on any icon in the icon bar on the left of the screen works,
  except for the top button. Clicking that button trashed the display
  with much flashing that sometimes hangs the system. See the 3 screen
  dumps of the system that are attached. This problem first appeared
  about a month ago.

  The computer is a dual boot Lenovo T-61 laptop with GRUB2 selecting
  either Ubuntu or Windows 7 (default).
