I can no longer get the HDMI port to work on my laptop (Asus TP300L) after a reboot earlier today. I can confirm that this is not a hardware issue as the external monitor works fine on win10 and another computer. I've tried connecting to my TV too which also fails with the same problem.
As far as I can tell, Ubuntu is no longer acknowledging that the system has an HDMI port.
