“闭嘴”现在需要我打招呼吗？

更新-删除我的USB wifi加密狗似乎可以解决该问题。禁用网络也是如此（但不能仅禁用wifi）。怎么办？ 更新2-“运行时间”命令说有2个用户登录。这肯定会引起我所描述的行为。我将进行深入研究，看看是否可以确定其他用户是谁。没关系，这仅是由于我在桌面上打开的终端。

如果我登录到任何帐户，则选择“关闭”或“重新启动”会将我带到欢迎者。迎宾员本身也发生了同样的事情-我留在那里。没有其他用户登录。

如果我不重新启动后，登录到一个帐户，如果我选择他们重新启动和关闭在迎宾菜单选项将工作立即在迎宾出现之后。在此处查看此引导图：https ://www.dropbox.com/s/ufb7s6ykvlbkjxj/jarlath-EP35-DS3-precise-20130116-3.png

如果我等待5秒钟或登录用户帐户-他们将无法使用。我已经测试了几次。查看此引导图（以用户身份登录）：https ://www.dropbox.com/s/yx6jgoo2c7fy6pp/jarlath-EP35-DS3-precise-20130116-4.png

sudo -halt和sudo reboot都可以正常工作。

我已从登录帐户（ps -A）输出所有进程，并将其留在此处：www.pastebin.com/e3WHtHYm

我以为是更新，软件中心的新内容（不太可能，因为当时我没有安装任何东西）或我发出的终端命令导致了此问题。这是问题开始之前我的.bash_history：pastebin.com/1DE5Tcd3

我的内核是3.2.0-35，我也尝试过引导旧的内核：

• 3.2.0-32、31、30、29、26、25、24、23、22->无差异

根据错误https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/838792中的建议，我尝试了：

• 使用su对我的/etc/init.d进行服务，并删除了1（ClamAV）。
• 杀死PulseAudio

这些都没有帮助。以下是更多背景信息；

解决方案： 我找到了解决方案。我没有将其用作答案，因为它无法确定根本原因，但是对于其他仅对自己的解决方案感到满意的人，应该尝试从grendndelman.net咨询该建议。

创建一个名为/etc/polkit-1/localauthority/50-local.d/usershutdown.pkla的文件（名称必须以.pkla结尾），并将以下内容放入其中：

[Allow Shutdown]
Identity=unix-user:*
Action=org.freedesktop.consolekit.system.stop-multiple-users
ResultAny=yes
ResultInactive=yes
ResultActive=yes

[Allow Restart]
Identity=unix-user:*
Action=org.freedesktop.consolekit.system.restart-multiple-users
ResultAny=yes
ResultInactive=yes
ResultActive=yes

如果登录的人不止一个，则按“关机”按钮将带您进入迎宾区。您仍然可以使用以下命令在命令行中关闭，sudo shutdown -h now

尝试sudo halt。找出是否也将您送往迎宾员会很有趣。

即使这可能不是您的问题，也可以通过出现此问题为任何人提供一个好的提示：

我以为我遇到了同样的问题：

原来，如果登录了另一个会话（SSH，ctrl-alt-f1等），则“关闭”无效。

以我为例，这是第一次发生，我打开了一个SSH会话来检查临时文件，但是从那时起，它始终是某种“现在检查日志中发生了什么”会话，这使问题非常一致。

退出所有ssh / other登录使关机再次起作用。

尝试从终端按ctrl + F1关机，然后运行sudo poweroff，或者只是从终端运行sudo poweroff，这可能会暂时解决问题

您可以使用以下命令

要么

w

查看是否有人以某种方式登录。

你可以强迫它。确保以前的用户注销而不是切换用户。
