I don't think I'm using the Nvidia drivers on the machine I reported this
from. That would mean they could not be the route cause.

Title:
Segfault from libX11.so.6.3.0
Status in libx11 package in Ubuntu:
Confirmed
Bug description:
Something went wrong with my Ubuntu 16.04 LTS desktop today. When I
got back to the system Mattermost and a Chrome were indicating that
the network was not working. I started to look about and it seemed
that my main ethernet network connection had lost its IPv4 address
somehow. ifconfig and the GUI network manager confirmed this.
To try and resolve this I physically removed the connector and the
plugged it back in. Shortly after I did this my GUI seemed to die out
and I ended up back at the login screen.
Once everything had calmed down I logged back in. After some digging
about in the logs I noticed the following in /var/log/kern.log
Oct 25 13:01:09 thorne-ul-dt kernel: [694321.877561] Mattermost[744]:

That seemed to be the correct time for the problem I noticed. What
exactly caused it I am not sure.
