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.
