dwm – Frequently asked questions

Q: I've got a 1 or 2 pixel gap between the right side of my terminal and the
   right side of the screen, and I want to turn it off.

A: This is due to the column-based nature of terminals. Terminals don't just
   insert space somewhere, but tell the WM they can't be resized in a certain
   way. The terminal can't use the "wasted space" anyway, so this is purely
   aesthetics.

   You can change `static const Bool resizehints = True;` to `False` in
   config.h to turn resizehints off. This wastes the same amount of  space
   inside the terminal window that would otherwise be wasted outside.
