Public bug reported:
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!
