Re: [xmonad] Retrieve number of screens.

Thanks

The type has to be in the X monad; try declaring it as X Int. (More specifically, the error message is telling you that you used a do expression, which produces a result in some monad ("m b"), but you declared the type as Int.)

XMonad.Layout.IndependentScreens exports the countScreens value for this purpose.

Both replies were very helpful. Regards, Mike
