I think this does the job:
我认为这可以完成工作：
gnome-session-save --logout
Also, take a look at the --help output, maybe you want to use the --force-logout option.

Your question is a bit vague. Are you trying to log out of a graphical session of a desktop environment (such as KDE/Gnome), as if the user clicked on "log off"?
你的问题有点含糊。您是否试图从桌面环境（例如 KDE/Gnome）的图形会话中注销，就像用户单击“注销”一样？
Then you need to find out if/how the desktop environment supports scripting to log out. On KDE for example you can use kquitapp.
然后您需要找出桌面环境是否/如何支持脚本注销。例如，在 KDE 上，您可以使用kquitapp.

Try restarting the display manager using one of the following, depending one which one you're using. You'll obviously have to have the proper permissions.
尝试使用以下方法之一重新启动显示管理器，具体取决于您使用的是哪一种。您显然必须拥有适当的权限。
/etc/init.d/xdm restart
/etc/init.d/kdm restart
/etc/init.d/gdm restart

It's a bit of a hack, but the way that screen's power detach does this is to determine its parent pid and send it a SIGHUP. (Clarification: This closes only the shell, so only works if you're running from a console - not a graphical login - so may not be what you're looking for.)
这有点像hack，但是screenpower detach的方法是确定它的父pid 并发送一个SIGHUP. （澄清：这仅关闭外壳，因此仅当您从控制台运行时才有效 - 而不是图形登录 - 所以可能不是您正在寻找的。）
