Comment:

 Installing xorg-server will also install its dependency xinit, which
 installs a launchagent that runs when you log in which sets up the DISPLAY
 environment variable such that, if you try to launch an X app, the X
 server will be started first. So "Cannot open display" means that the
 DISPLAY environment variable doesn't point to a valid display, either
 because xinit's launchagent isn't running or because you're overriding the
 DISPLAY environment variable in a shell startup script or somewhere else
 (if so, remove that override).
