The Debian desktop environment does not allow root login by default, so you need to modify the configuration.

First, let Debian log in using root

1) first modify the configuration file (/ etc/gdm3/daemon.conf) of gdm3, and append the following line after the [security] field:

The code is as follows:

[security]

AllowRoot = true

2) finally modify the login pam file of gdm3:

The code is as follows:

Vi / etc/pam.d/gdm-password

Comment out auth required pam_succeed_if.so user! = root quiet_success / / add # before this line

Let Debian log in automatically as root

1) first modify the configuration file (/ etc/gdm3/daemon.conf) of gdm3, and append the following two lines after the [daemon] field:

The code is as follows:

AutomaticLoginEnable = true / / changed to true

# AutomaticLogin = root / / automatically log in as root

If you want to wait a few seconds before logging in, you can add the following to the [daemon] field:

The code is as follows:

TimedLoginEnable = true

TimedLogin = root

TimedLoginDelay = 5 / / the login delay is 5 seconds, which can be modified

2) finally, modify the automatic login pam file of gdm3:

The code is as follows:

Vi / etc/pam.d/gdm-autologin

Comment out [/ ode] auth required pam_succeed_if.so user! = root quiet_ comment [/ code]. / / add # before this line to remove the restriction that Debian does not allow root to log in.

Just restart the system!
