Xmonad showing only 1 window on screen

Question

I decided to try Xmonad today and installed it on VM with Arch linux. Without spacing it works perfectly, but when I am adding it, Xmonad only show one newest window on screen (if I open new window, old one just disappear).
There is my simple configuration I made using information from there:

import XMonad
import Xmonad.Layout.Spacing

main :: IO ()
main = xmonad $ def
    { layoutHook = spacingWithEdge 10 $ Full
    }

Sorry if I am being dumb. This is my first time using Xmonad and Haskell.

Answer 1

Your configuration replaces the default layoutHook with one that only makes the Full layout available. Changing the relevant line to...

    { layoutHook = spacingWithEdge 10 $ layoutHook def

... should add the spacing while keeping all the default layouts available. Note that:

• You can switch between the available layouts, with the default key binding being Alt + Space; and

• You can switch the focused window, even while using the Full layout, with the default key binding being Alt + Tab.
