Hello, try adding the option -beagle_info to your command line - if it is not present, the application indeed tries to show you a dialog containing various information and configuration switches. That is the reason why it searches for means to display windows - in your case: an X11 encironment.

For reference: https://github.com/beast-dev/beast-mcmc/blob/master/src/dr/app/beast/BeastMain.java#L766

Yes as @elbosso says - the absence of an XML file on the command line means BEAST tries to open a dialog box for you to specify one. The -citations_file needs an XML file so it knows what models you are using and thus what citations to include. On a linux environment it will try to open an X11 window.
