【求助】lubuntu默认root自动登陆！
装了一个lubuntu server版，本来都很顺利，可是昨天连了VGA显示器一看发现居然root已经自动登陆了，设置了root密码也是一样自动登陆。个人能力有限，实在不知道那里出了问题，希望大家能够提供帮助，谢谢！
ps.linaro用户已经被我删掉了。 自己解决了!
在/etc/default目录下有一个autogetty文件，内容如下：
# here you can provide what to run instead of /bin/login
AUTOGETTY_ARGS="-n -l /usr/bin/auto-root-login"
# Should autogetty be enabled?
ENABLED=1
只要将ENABLE=1改成ENABLE=0就可以了。 正需要的，谢谢 我试过了，修改之后，串口无法控制，只能用SSH控制 wpd 发表于 2014-7-17 01:38 static/image/common/back.gif

试过了，本地还是依然root登录，ssh远程已经无法访问。。。。
谁解决这个问题了，粗来分享下经验子撒~~ 找到解决办法了。。。。哈哈哈哈~~~~~
执行：mv /etc/init/openvt.conf /etc/init/openvt.conf.bak 就可以解决问题啦！！！
参考资料：Ok, I figured it out. So this is how login works. There is an init script in /etc/init/tty1.conf which runs getty. Getty is a program that waits for login connections, and then authenticates a user. I initially thought getty was being run with autologin, and so I looked for a line in /etc/init/tty1.conf like
exec /sbin/getty -8 38400 -a root tty1
which means, open an 8bit terminal at 38400 baud and autologin the root user into tty1. But when I looked at the file, there was no -a option to autologin the root user. I'm stating this because /etc/init/tty1.conf should be the first place to look if others face the same issue.
Then I looked through the /etc/init/ directory and found a file called openvt.conf. This had the following line:
exec /bin/login -f root
This was the culprit. The login command with the -f option automatically logs the user in without authentication.
Since the openvt.conf file is intended to be an upstart service, it has to be disabled in a particular way, although one can also simply delete the file. See this askubuntu post about upstart. In short, either delete the openvt.conf file, or run
echo manual | sudo tee /etc/init/openvt.override
and then root is no longer logged in automatically.出处：http://superuser.com/questions/783560/linaro-system-boots-to-root-without-password
