没有控制台，我不能关闭也不能重新启动

Question

在从11.04更新到11.10之后，我的机器中出现了一种有线行为：

关机GUI方法(包括重新引导)只会导致注销，而在登录屏幕上，关机或重新引导选项会做任何事情(如果您想知道，重启会出现在关机对话框中)。

唯一可以重新启动或关闭的方法是低端控制台sudo shutdown -h now或sudo reboot。这对我来说没问题，但对其他用户来说就不行了。

怎么解决这个问题？

更新

当从我的桌面选择关机时，syslog输出是：

AptDaemon: INFO: Quitting was requested

我怀疑gnome-session[1836]: WARNING: Unable to stop system: Authorization is required行与这个问题有关。

当从登录屏幕中选择shutdown时，输出与指向的行相同。这是输出：

你们安装了吗？这就是我的罪魁祸首。这是它的bug票证：https://bugs.launchpad.net/ubuntu/+source/rabbitmq-server/+bug/670289

Answer 2

我也有同样的问题，但对我来说，它是通过以下解决方案解决的。也许它也能帮助你的系统。https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/838792/comments/24

Answer 3

我也遇到了同样的问题(在我使用Gentoo的时候也是一个类似的问题)，这个问题对我来说是有效的：https://www.grendelman.net/wp/policykit-adventures/。在12.04进行了测试，问题就解决了。不过，我会用它作为临时修复，因为有东西告诉我，当每个人都可以在不检查其他运行会话的情况下重新启动主机时，这个错误并不是那么安全。在我的例子中，这个bug只是在我在VTs上运行其他会话时，或者当有其他人通过SSH登录时才出现的。无论如何，希望这个bug能为您修复。享受吧：
