I couln’t get `displaysize()` to return my monitor resolution.

I know I can get it with the help of e.g. [Gtk.jl](https://github.com/JuliaGraphics/Gtk.jl), but I’d prefer avoiding using an external package. Is there a way in Julia `Base` to obtain the screen resolution ?

Julia (the core language and the standard libraries) does not know anything about graphical output, so you will have to rely on a package for that.

For a specific OS, you may be able to formulate a command line query though (eg from the output of `xdpyinfo` on X).
