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.
Contents
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 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
Warning: If you are currently in an X session on the same tty configured in the service file, starting
autologin@ttyX.service will kill your X server.Tips & Tricks
Avoid 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
