Jamie Rave, 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 xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.

As part of the big bug clear up for 16.04 LTS I am marking this bug as Wont Fix. These types of crasher are better handled by errors.ubutnu.com which can collate similar crash reports to help us identify persitent bugs rather than one-off crashes. Sorry we are not able to help with this specific issue. If you are still experiencing this crash, please re-open the bug and add the tag “desktop-bugscrub-reopen”. See https://wiki.ubuntu.com/BigDesktopBugScrub for more information.
