Public bug reported:
This crash just happened after the latest updates installed from the
main Ubuntu repos as of 2016-02-08 01:30 GMT when trying to login to a
desktop.
Because compiz crashes before establishing a usable desktop, I have had
to revert back to a snapshot from 2016-02-05 to report the bug. So I
don't know if apport is reporting the correct versions of installed
packages.
I saw a similar thing happen a couple of weeks ago, and it turned out to
be due to an nvidia 352 driver update from xorg-edgers; I purged the
package and went back to using the nvidia 352 driver from the main
repositories. This fixed the problem at the time - I was able to install
all updates and compiz kept working. Note that I'm only using the nvidia
driver so bumblebee can turn off the nvidia card.
