我刚刚进行了更新,现在,每当屏幕锁定时(无论是手动锁定还是在超时后自动锁定),我都会输入密码,然后解锁一段时间,但是所有窗口边框都消失了,就像窗口一样管理员死了,大约2秒钟后,它再次锁定。之后,我无法返回系统。当我运行 unity 命令时,它抱怨它无法连接到 org.gnome.ScreenSaver ,然后出现段错误。

我该怎么办?而且,如果没有解决方案,我该如何还原更新?

I have just had an update, and now, whenever my screen locks (be it manually or automatically after a timeout), I type my password, and it unlocks for a bit, but all window borders are gone as if the window manager is dead, and after about 2 seconds it locks again. I have no way to return to the system after that. When I run the unity command, it complains that it can't connect to org.gnome.ScreenSaver, and then segfaults.

What do I do? And if no solution is known, how do I revert the update?

在Ubuntu 13.10中,Brightness&amp;锁定对话框可让您在闲置1、2、3、5、10、30和60分钟后锁定屏幕。是否可以设置此列表中未显示的其他空闲时间(例如15分钟)? (坦率地说,只提供一些这样的选择是很愚蠢的。为什么不允许任意数量的分钟?) ...

2  音频和锁屏热键损坏  ( Audio and lock screen hotkeys broken ) 
几天前(可能在某些软件包更新之后),我的一些热键停止了工作。不再可以通过键盘上的"提高音量" /"降低音量" 热键更改音量,也无法通过STRG + ALT + L锁定屏幕,这简直是无能为力。 当我处于Ubuntu的键盘设置中时,单击"降低音量" 选项,然后按热键即可正确检测到热键。 有没有人知道如何解决此问题,或者...

5  屏幕锁定后必须登录两次  ( Having to log in twice after screen lockout ) 
我在Ubuntu 10.04.2 LTS桌面上。 (通过扫描/ boot,看来我可能位于2.6.32-29-generic内核上?不确定)。 无论如何,在我上一次系统更新之后,现在我的屏幕锁要求我登录两次,而之前不需要这样做。 我认为这是一个错误?在修复该错误之前,是否有一种方法现在可以撤消此操作? ...
