Emacs doesn't fill window

Question

I'm using GNOME and xmonad. When I first open Emacs, it doesn't use the full width and height of its window. If I then change the size of the window, emacs corrects itself to fill the window, and works perfectly thereafter. How can I fix this?

Answer 1

From man emacs:

starting emacs with emacs -fs opens emacs in full screen mode

to automate this, add the following to your .bashrc file (found in /home/user/.bashrc):

alias emacs='emacs -fs'

Answer 2

I don't think it's fixable; this is a longstanding Emacs bug/annoyance.

Answer 3

Works for me if placed in the last line of my .emacs:

(if (window-system) (set-frame-size (selected-frame) 1280 1000))
