由于 MATE 只是 GNOME2 的一个分支，显然可以使用以下命令将窗口管理器替换为另一个（即 xmonad）mateconftool-2 -s /desktop/mate/session/required_components/windowmanager xmonad --type string：. 这在我登录 MATE 时启动 XMonad 的意义上是有效的，但是，看起来 xmonad 正在尝试平铺面板或其他东西。其中一个面板实际上填满了它不应该占据的所有空间（顶部和底部留空）并且系统完全无法使用（需要重新启动）。

我唯一的假设是 xmonad 没有正确地忽略面板。
我正在使用从 12.04 升级的 Ubuntu x64 12.10
编辑：我尝试添加className =? "mate-panel" --> doIgnore到 xmonad.hs 中的 manageHooks。没有不同。
