I'm connecting my server to Putty trying to use Xming to display GUI elements but unfortunately I'm not getting it. Whenever I try to run a command line program it returns me the errors.
NOTE: X11 option in Putty is active
Firefox:
Error: GDK_BACKEND does not match available displays
GEdit:
Error: XDG_RUNTIME_DIR not set in the environment.
So I kept thinking, does it have to have a graphical interface for Xming to work?
