====== Raspberry Pi Autologin ======

This note are about **Raspbian** based on **Debian 9 Stretch**, which uses **systemd**.

Using **raspi-config** you can go to the menu **Boot Options** => **Desktop / CLI**, where you can choose:

  * B1 Console
  * B2 Console Autologin
  * B3 Desktop
  * B4 Desktop Autologin

Beware that you should execute **raspi-config** after a **sudo su**, otherwise options B2 and B4 **cannot determine the non-root user** to be used. You can force that user setting the shell variable:

<code>
export SUDO_USER=pi
</code>

The **Desktop Autologin** is performed with **Lightdm Desktop Manager**, configuring the file **/etc/lightdm/lightdm.conf**:

<file>
autologin-user=pi
</file>

Choosing the Desktop Autologin will enable also a **Console Autologin** on the VT1, with the same non-root user. The config is obtained via a symlink:

<code>
/etc/systemd/system/getty.target.wants/getty@tty1.service ->
    /lib/systemd/system/getty@.service
</code>

and a configuration file **/etc/systemd/system/getty@tty1.service.d/autologin.conf**.
