Hello together, I am new to xmonad. I installed it on my gentoo system using the haskell overlay and "emerge xmonad". No I want to change the configuration: I tried uncommenting the following lines in /etc/portage/savedconfig/x11-wm/xmonad-0.4.1: (Line 69) import qualified XMonadContrib.HintedTile (Line 248) , XMonadContrib.HintedTile.tall nmaster delta ratio and did emerge -av xmonad: Calculating dependencies... done!
