Unable to have full-screen in Mac's Xmonad

Question

I installed the newest X11. I run the following command unsuccessfully after sourcing ~/.profile

$exec /usr/X11/lib/X11/xinit/xinitrc

I get a message

Screen is terminating

and I do not see any evidence of XMonad.

I run the command the second time, and I get

zsh: permission denied: /usr/X11/lib/X11/xinit/xinitrc
Process completed

and my terminal shuts down.

How can you have the full-screen mode in Mac's Xmonad by xinitrc?

Answer 1

exec is a shell built-in. If you insists on using it with sudo, you should do something like:

sudo bash -c "exec ...."

But that is pretty much pointless, if you use sudo anyway. Just drop the "exec" altogether.
