 要使用root自动登录，需要修改三个地方：

• 1.sudo passwd root
• 2.sudo passwd root --unlock
• 3.修改脚本

vi /etc/lightdm/lightdm.conf.d/20-lubuntu.conf

[SeatDefaults]
autologin-user=root
autologin-user-timeout=0
user-session=Lubuntu

10#Ubuntu14.04 root登陆错误“Error found when loading /root/.profile

ubuntu修改用户名


正确的命令为:


id user_old


usermod -m -d /home/user_new -u 1001 user_old;
或
usermod -d /home/user_new -m -u 1001 user_old;
最后,再改变用户名和组名为user2:
usermod -l user_new user_old;


groupmod -n user_new user_old




id dou
root@rk3288:~# id dou
uid=1000(dou) gid=1000(dou) groups=1000(dou),27(sudo)
