问题描述:

Ubuntu 14.04,出现开机时就自动登录上,不用输入密码.当待机唤醒后又出现登录界面,但是输入密码后,总是提示不合法.重启后又自动登录进入系统.

.xsession-errors的内容如下:

Script for ibus started at run_im.
init: unity-settings-daemon main process ended, respawning
init: hud main process (1360) terminated with status 1
init: unity-panel-service main process (1374) terminated with status 1

开机就自动登录上，很可能你在安装的时候选择了自动登录功能。
待机唤醒输入密码提示不合法，很可能你把密码忘了。
