发表于 更新于 阅读次数： 本文字数： 2.6k 阅读时长 ≈ 5 分钟

dwm（Dynamic Window Manager）属于动态窗口管理器，可以自定义不同窗口的出现规则如平铺或者堆叠。

rdesktop 是一个在 Unix/Linux 下访问 Windows 远程桌面的客户端程序.

1. 背景

需求是有一台性能极差的linux服务器，想在上面安装rdp ,把它当成廋客机来使用。这时候就需要一个窗口，在无法安装桌面的情况下，dwm+rdesktop无疑是比较合适的解决方案。

1. 安装dwm

  1. 先用apt安装

    1
    apt install dwm

  2. 安装完成后尝试启动

    1
    startx

  3. 可能遇到以下问题
