Ubuntu – Second Monitor is not detected after upgrading to 18.04.1

Any help would be appreciated. I've looked over similar threads and have tried restarts and installing lightdm, but haven't had any success. I'm trying to use a second monitor through my laptop's single HDMI port and it worked yesterday before updating to 18.04.1, but now it isn't being detected.
This is for a Toshiba Satellite, I don't know the exact model it's a couple years old the sticker with that info has rubbed off.

I have tried it with a second monitor and a different cable as well.

The xrandr output is:

Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192
