Comment 82 for bug 771875

That's a regression in between of ubuntu 14.04 and ubuntu 16.04. In ubuntu 14.04 I never experienced this problem, while using this feature a lot (I had it up-to date before upgrading. And I had HES 14.04.4 installed).

Note that I just updated the very same machine from 14.04 to 16.04. So this is not hardware related (unless the change uses _new_ features of hardware). Tested on Dell Latitude E5510 bare metal.

It seems to affect other users as well:
