从11.04更新到11.10后，我的机器中出现有线行为：
关闭GUI方法（包括重新启动）只会导致注销，并且在登录屏幕上，关闭或重新启动选项均会执行任何操作（如果您想知道，重新启动会显示在关闭对话框中）。
我可以重启或关机的唯一方法是通过控制台sudo shutdown -h now或sudo reboot。这对我来说是可以的，但对其他用户则不行。
如何解决？
更新资料
从桌面选择关闭时，系统日志输出为：

我怀疑该行gnome-session[1836]: WARNING: Unable to stop system: Authorization is required与问题有关。
shutdown从登录屏幕选择时，从所指向的行输出是相同的。这是输出：

首先，请在“关机”对话框中删除有关重新启动的烦恼。这与您的问题无关。如果困扰您，您可以提出错误。其次，在尝试通过GUI关闭失败后，请查看日志文件（例如/ var / log / messages）。

@Jan我做了你建议我的事情。另请注意，/ var / log / messages不再存在；我不知道，但是[1]向我展示了怎么做：使用/ var / log / syslog [1] askubuntu.com/q/51265/10580
