Here is a copy of my unity-system-compositor.sleep.
A failed upgrade is possible: before I upgraded to 16.10, I tried purging a few PPAs because they are often problematic and purging the overlay-ppa proved very difficult (ended up chasing the word "overlay" in Synaptic to completely remove any trace).
Currently, my version of unity-system-compositor is 0.7.1+16.10.20160909.1-0ubuntu1 and Synaptic marks it as the latest version.
