I'm having an issue where the screen randomly goes blank/black while I'm using the system. The blank does not appear to be associated with screen refreshes or anything specific. It happened about 3 times while writing this simple paragraph, but sometimes doesn't happen for tens of minutes of usage. The screen blanks ONLY happen on external monitors (HDMI from the side ports of the laptop, and Display port from the laptop dock). When I have two monitors connected via display port, the only screen that goes black is the one with my cursor on it.
I'm using a fresh install of Ubuntu with Cinnamon as my desktop. I assume the somewhat new Intel Sky Lake integrated may be the issue after reading other threads.
Here's my info:
HP EliteBook Folio 1040 G2
sudo lshw -c video

Thanks for the help in advance!
