Error: cannot open display: :99

Hi,

I'm trying this on my (Ubuntu) desktop before trying on Unraid - I seem to have a issue where it claims it cannot connect to the display (I assume X11), anyone seen this issue?

$ docker logs -f thunderbird

@esticle can you post your docker run command? It seems like that you've missed the ENV TURBOVNC_PARAMS=-securitytypes none but that wasn't in the Readme and is necessary because I've switched over to TurboVNC, updated it in the meantime.

Thanks @ich777 absolutely correct, I had TURBOVNC_PARAMS empty as the README said at the time - adjusting it fixed it for me
