[xubuntu-users] 15.10 Occasionally Hard Freezes

[Ian]

I am using 15.10 wily werewolf. I updated my system (apt-get update and
apt-get dist-upgrade), installed ubuntu-restricted-extras, and ran apt-get
autoremove. I update and autoremove pretty regularly, so there wasn't much
in the way of updates available or things to be removed. Installing
ubuntu-restricted-extras just swapped out my FFMPEG library versions. While
I am sure those are all good things to do, I am doubtful that any of them
will help the freezing problem.

To clarify, when the computer freezes, I can't press ctrl+alt+f1 to exit
xwindows to tty. It is really hard-frozen. I am using a Thinkpad x230.
