Ubuntu – Screensaver/black screen doesn’t start on its own

nvidiapower-managementscreensaverunityxorg

Running 16.04, 5 minute inactivity timeout, sometimes the screensaver (or blank screen, to be accurate) won't start until I hit Super+L and lock the session. Suggestions?

Running Nvidia 367 drivers, currently switched to my integrated Intel card though. Laptop is a Thinkpad T460P, and I am running TLP.

One suggestion is to try xscreensaver:

sudo apt-get install xscreensaver

On my own system I have had more reliable power saving / powering down / blanking with this application. A screenshot from my own Xenial system to demonstrate the power management options:

And as a bonus there are some truly amazing screensavers...
