====== 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:
export SUDO_USER=pi
The **Desktop Autologin** is performed with **Lightdm Desktop Manager**, configuring the file **/etc/lightdm/lightdm.conf**:
autologin-user=pi
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:
/etc/systemd/system/getty.target.wants/getty@tty1.service ->
/lib/systemd/system/getty@.service
and a configuration file **/etc/systemd/system/getty@tty1.service.d/autologin.conf**.
