系统环境：Red Hat Enterprise Linux Server 6.0
启动时提示：
The configuration defaults for GNOME Power Manager have not been installed correctly.Please contact you computer administrator.
There is a problem with the configuration server(/usr/libexec/gconf-sanity-check-2 exited with status 256).
解决办法：
删除/tmp中的所有文件（包括隐藏文件），然后将/tmp目录的权限改为777，之后重启即可。
[root@RHEL-min tmp]# ls -A |xargs rm -rf *
[root@RHEL-min tmp]# chmod 777 .
[root@RHEL-min tmp]# init 6
