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 [[Xorg|X server]] are described in [[Start X at Login]].
== Installation ==
=== Creating the {{ic|.service}} ===
Create a new service file similar to {{ic|getty@.service}} by copying it to {{ic|/etc/systemd/system/}}:
# cp /usr/lib/systemd/system/getty@.service /etc/systemd/system/autologin@.service
{{Note|{{ic|/etc/systemd/system/}} takes precedence over {{ic|/usr/lib/systemd/system/}}.}}
Then change the {{ic|ExecStart}} line to include the {{ic|-a ''USERNAME''}} parameter:
ExecStart=-/sbin/agetty --noclear -a ''USERNAME'' %I 38400
{{Tip|The option {{ic|1=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 [[Start X at Login|starting X automatically]]. See {{ic|man systemd.service}} for more info.}}
=== Enabling the {{ic|.service}} ===
Finally, you need to disable the old {{ic|getty@tty''X''.service}} for the specified tty and enable the new {{ic|autologin@tty''X''.service}}, e.g.:
# systemctl daemon-reload
# systemctl disable getty@''tty1''
# systemctl enable autologin@''tty1''
To test it out, use:
# systemctl start autologin@''tty1''
{{Warning|If you are currently in an X session on the same tty configured in the service file, starting {{ic|autologin@tty''X''.service}} will kill your X server.}}
== Tips & Tricks ==
=== Avoiding unnecessary dmesg errors ===
To avoid errors related to {{ic|display-manager.service}} in dmesg, you should set the default target to multi-user instead of graphical:
# systemctl enable multi-user.target
