HDMI output is not working for me on
I have tried solutions suggested in other threads such as using the power reset button, changing bios assist mode, updating firmware (using fwupd).
In windows and Linux the Thunderbolt device is not listed. Not sure if this is related or not. Is it possible that this is bad hardware?

Welcome to the Community,
Another step to further isolate the problem would be using a different HDMI cable to output the video. It would be best to try this on Windows 10, since Ubuntu 18.04 is not compatible with X1 Carbon 6th Gen as per Linux Certification list,
If it's still the same, despite the Thunderbolt Firmware updated, we highly recommend contacting our support for warranty claim here,

I see. While these known working cables and monitors are connected, try pressing Windows key + P. If it still shows No Signal with these available option to project, likely there's an issue with the actual HDMI Port. It would be best as well to contact our support using the link mentioned above, so they can provide you repair options.
