通过XDMCP 远程登录

什么是 XDMCP?

GNOME视窗能够同时支持几个不同的用户。不像只是复制当前的屏幕内容到一个终端的vncviewer那样，XDMCP允许几个不同的用户在同一时间登陆和运行不同的GNOME进程.所以如果你有一台运行Ubuntu的性能良好的电脑，其他电脑性能不好的用户可以登录进入你的电脑，并且运行在你电脑上能够使用的大型程序。

怎么开启XDMCP的功能

在性能良好的电脑上开启XDMCP，点击如下菜单

System -> Administration -> Login Window

在Login Window首选项对话窗选择如下：

Remote Tab -> Style: Same as Local -> Close the dialog window -> Restart the PC

How to login from another PC running Ubuntu

1. Reboot the slow PC and stop at the login screen
2. Click Options at the lower left corner of the login screen
3. Select "Remote Login via XDMCP"
4. On the dialog window, type in the host name or ip of the fast computer you want to login to
