DISPLAY is not set error

FAQ
1

Hi

I am trying to get a server running on Ubuntu 24.04 .
I’m using Docker Desktop I have followed the build instructions, but keep getting the error “DISPLAY is not set” when I try to launch the container. I have edited the config file ( see below ) I’m trying to output to a Decklink card. Any help would be great as I can’t find a reference to what the error is referring to in any of the Docs, and looking around, I think my config file is correct?.

I think it is referring to the X11 Display. It is how Caspar used to get a connection to opengl.

I would recommend you to take a look at this: feat: support running without x11 on linux by Julusian · Pull Request #1624 · CasparCG/server

There has been great work done to help with this problem.
