【求助】lubuntu默认root自动登陆！

wpd

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！

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。

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！！！

1. 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
   
2. exec /sbin/getty -8 38400 -a root tty1
   
3. 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.
   
4. 
   
5. Then I looked through the /etc/init/ directory and found a file called openvt.conf. This had the following line:
   
6. exec /bin/login -f root
   
7. This was the culprit. The login command with the -f option automatically logs the user in without authentication.
   
8. 
   
9. 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
   
10. echo manual | sudo tee /etc/init/openvt.override
    
11. and then root is no longer logged in automatically.
