So I thought I would share my experience to maybe help anyone else who encounters it. I’ve gotten OSMC running smoothly off of a USB drive and recently installed the Broadcom Crystal HD BCM700015 mini pci-e card. I run my A/V through component cables and have altered the /etc/X11/xorg.conf file per the OSMC Wiki ( Here ). My device downloads update and then prompts to upgrade. When the upgrade was finished, my apple tv rebooted and I was presented with a black screen and nothing more. I could still SSH into the device, so I could tell that everything was physically running fine. I then checked my /etc/X11/xorg.conf file and noticed that it had been changed to an alternative configuration. Editing it to re-enable the component cables solved my problem.
The files that updated to cause this problem in the first place were:
