Start X at Login

This article describes how to automatically log in to a virtual console at the end of the boot process. This article only covers console log-ins; methods for starting an X server are described in Start X at Login.

Installation

Creating the .service

Create a new service file similar to getty@.service by copying it to /etc/systemd/system/:

# cp /usr/lib/systemd/system/getty@.service /etc/systemd/system/autologin@.service
Note: /etc/systemd/system/ takes precedence over /usr/lib/systemd/system/.

Then change the ExecStart line to include the -a USERNAME parameter:

/etc/systemd/system/autologin@.service
[Service]
[...]
ExecStart=-/sbin/agetty --noclear -a USERNAME %I 38400
[...]

[Install]
WantedBy=getty.target
Tip: The option Type=simple (default) will delay the execution of agetty until all jobs (state change requests to units) are completed. On the other hand it may cause systemd boot-up messages to pollute the login prompt. This option is more useful when starting X automatically. See man systemd.service for more info.

Enabling the .service

Finally, you need to disable the old getty@ttyX.service for the specified tty and enable the new autologin@ttyX.service, e.g.:

# systemctl daemon-reload
# systemctl disable getty@tty1
# systemctl enable autologin@tty1

To test it out, use:

# systemctl start autologin@tty1

Tips & Tricks

Avoiding unnecessary dmesg errors

To avoid errors related to display-manager.service in dmesg, you should set the default target to multi-user instead of graphical:

# systemctl enable multi-user.target
