Is it possible to run a unity standalone on an amazon aws ec2 ubuntu instance?

Or will unity run only on a linux desktop box with a graphics card and a desktop interface?

If it is possible what would need to be installed on the instance and what would the unity build settings need to be?

I believe that it is possible. You may find that the --nographics option helps. We also found that it was essential to use xvfb-run to get it to run. You will find a bit more information here:

I found that it is possible, but not as simple as I expected. The best solution for me was to run a barebone graphical interface in the ec2 instance from the command line. I wrote some instructions here: Run Your Unity ML Executable in the Cloud
