Comment 4 for bug 1534798

I have the same problem.
It was on Ubuntu 14.04, and now it also on 16.04.
I use manual package installation, maybe it's depends on some specific package?

There is a log of my installation (on Russian, but you can find there installed packages):
16.04: https://github.com/Avol-V/my-light-ubuntu/tree/5f1fed7e09b0d6f645203ae11c9de5cdaa4501a7
14.04: https://github.com/Avol-V/my-light-ubuntu/tree/ff30d6aa08bfc407f541b93822690cd7df6ec6f4

I have the same problem with this installation on two different computers.
In both situations I install pulseaudio instead of alsa and didn't install compton.
