1. check /etc/pam.d/gnome-screensaver,发现没有错误

2. 网上说/sbin/unix_chkpwd的属性不对，检查了也没问题

3. 查看/etc/passwd,/etc/group,/etc/shadow,/etc/gshadow发现/etc/gshadow属性不对，改为下面的样子:

@H_301_14@ -rw-r----- 1 root shadow 813 Sep 8 14:08 /etc/gshadow

@H_301_14@ -rw-r----- 1 root shadow 1455 Sep 8 14:10 /etc/shadow

@H_301_14@ I had this same issue. It turned out that my problem was that ~/.Xauthority was updated as root,and from then on only root could read it. It stopped me from starting any X session from my username. I had to sudo rm ./.Xauthority and it worked fine after that.
