Dual Monitor, one monitor (random?) doesn't power up after lock.

[Dennis Fehr]

If I switch to a different virtual terminal, and then back to F7, it powers back up. I have a laptop, and an Acer Monitor connected via HDMI. Randomly (not always), one (never both) of the displays powers back up.. Note: The monitor does attempt to search for connected devices it seems (cycles through it's sources), but seems to find none? But I guess does get poked when powering on? Looking at Xorg.0.log and dmesg don't really seem to give any hint about it.. and it's only ever happened when I upgraded to Ubuntu 16.10, from 16.04 (64bit)..

Any help would be greatly appreciated!

Does nobody else have this issue? When I open the laptop lid after lock, I still get it, 90% of the time. It's either monitor, it's not always just one.
