XMonadにはスリープ機能がありますか？

私の話は少し長いです。私はLinux Mint Triciaを使用しています。 Cinnamonが付属し、しばらくしてXFCEを使い始め、Cinnamonを取り除いた。しばらくすると、GNOMEをインストールしてXFCEを削除し、XMonadがインストールされました（GNOMEは削除されませんでした）。問題があります。しばらくすると画面が黒くなります。私はこれをしたくない！これはXMonadですか、それともX11ですか？それとも、GNOMEが私のXMonadを妨げるものはありますか？

XMonad + XMobar +窒素+コンプトンがあります。
