我跟着本指南在我的 Debian 7.1 上安装 Xmonad GUI。执行以下命令后安装成功完成：
aptitude install xmonad libghc6-xmonad-dev libghc6-xmonad-contrib-dev
执行后：
$ xmonad
我收到以下错误：
deepsy@deepsypc:~$ xmonad
/home/deepsy/.xmonad/xmonad-x86_64-linux: executeFile: does not exist (No such file or directory)
X Error of failed request: BadAccess (attempt to access private resource denied)
Major opcode of failed request: 2 (X_ChangeWindowAttributes)
Serial number of failed request: 7
Current serial number in output stream: 8
我已尝试用apt-get purge xmonad重新安装它apt-get install xmonad，但仍然出现相同的错误。

看来您已经有一个正在运行的窗口管理器。试试吧xmonad --replace！
