这可能与其他密码相关的问题重复,但它有点古怪.

我的Ubuntu 12.10系统中有3个帐户(一个标准和两个管理员).其中一个管理员帐户是我的主要开发帐户,突然在昨天之前,它开始变得怪异(因为最新的更新 – 内核和其他：

>在欢迎阶段,当我输入密码时,它会立即返回“密码不正确”.它甚至没有检查. (N.B：密码绝对正确)

>在TTY,无法登录,一旦我输入我的登录名然后输入密码,它会立即重新提示我输入登录名…感觉就像认证此帐户的路径被意外锁定或访问密封.

我使用我的第二个管理员帐户登录并更改了麻烦帐户的密码,但没有运气,将密码恢复为原始值并将帐户设置为自动登录.重新启动,然后,确实帐户登录.然而,异常仍然存在：

>我无法执行root权限操作(sudo& gksudo).输入密码后,没有任何反应.接受密码的唯一时间是屏幕被锁定并且提示我输入密码以解锁密码.

我检查了我的主文件夹的所有权,没关系.一些帮助非常感谢.

总结一下：

– 无法通过lightdm登录

– sudo,gksudo& pkexec没有成功

– su命令失败

– 如果我提供sudo命令的密码不正确,它会检查并返回“密码不正确”,但是如果我提供了正确的密码,它什么都不返回.

– 我自动登录时接受密码密钥环.

– 解锁屏幕时接受密码.

>我已经更改了密码,并检查我的用户名是否属于(sudo,admin,adm,….)等组.
