[xmonad] Refresh display, adapting to monitor resolution

[Jean-Baptiste Mestelan]

Thank you very much, Alexandre, for your kind answer.

Yes, I vaguely suspected that the answer might come from X tooling, rather
than XMonad itself; but thanks for putting up with me.

Looking at autorandr right now: it looks perfect for what I want.

Best regards.
