I've been using an Ubuntu 16.04 laptop at work, adding an additional monitor via HDMI. Today the laptop has not recognized any displays plugged into the HDMI port. I booted into my windows install and the hdmi was functioning correctly.
When I got to displays > detect displays only my laptops built-in display shows
Monitors: 1 0: +*eDP1 1920/345x1080/194+0+0 eDP1
I've attempted a solution here. This was not an issue until just today, and to my knowledge nothing has changed in the OS since then. I have run
sudo apt-get update
sudo apt-get upgrade
to ensure I have the latest updates.
I'm using an Asus Q551LB laptop with a Nvidia Geforce 940m integrated chip
Anyone have any idea how to troubleshoot this? It would be much appreciated.
