I'm using Ubuntu 18.04 with i3-wm, and nvidia-driver-430. After Ubuntu puts itself to sleep after inactivity, and I log back in, only 2 out of my 3 monitors turn back on. My primary monitor (display port), and my second monitor (hdmi), but my third display port monitor does not turn on. If I look in nvidia-settings it's listed as "disabled". If I enable it in there, it does nothing. If I unplug the monitor and plug it back in it then gets recognized and functions as normal. Any idea where I can go from here? Thanks.
