How can I configure systemd to automatically log me in to my desktop environment, preferably without using a login manager? I'm using Arch Linux.

  • Which login manager are you using? Some (GDM, KDM, iirc, maybe more) already support autologin so you would only need to enable the service for them.

  • I'm currently using SLiM and it can be configured to autologin, but without a display manager the boot process would be faster and more flickerless :)

This is described in the ArchWiki:

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

This basically copies the already existing getty@.service to a new file autologin@.service which can be freely modified. It is copied to /etc/systemd/system because that's where site-specific unit files are stored. /usr/lib/systemd/system contains unit files provided by packages so you shouldn't change anything in there.

You will then have to symlink that autologin@.service to the getty service for the tty on which you want to autologin, for examply for tty1:

ln -s /etc/systemd/system/autologin@.service /etc/systemd/system/getty.target.wants/getty@tty1.service

Up to now, this is still the same as the usual getty@.service file, but the most important part is to modify the autologin@.service to actually log you in automatically. To do that, you only need to change the ExecStart line to read

ExecStart=-/sbin/agetty -a USERNAME %I 38400

The difference between the ExecStart line in getty@.service and autologin@.service is only the -a USERNAME which tells agetty to log the user with the username USERNAME in automatically.

Now you only have to tell systemd to reload its daemon files and start the service:

systemctl daemon-reload
systemctl start getty@tty1.service

(I'm not sure if the service will start properly if you're already logged in on tty1, the safest way is probably to just reboot instead of starting the service).

If you then want to automatically start X, insert the following snippet into your ~/.bash_profile (taken from the wiki again):

if [[ -z $DISPLAY ]] && [[ $(tty) = /dev/tty1 ]]; then
    exec startx

You will have to modify your ~/.xinitrc to start your desktop environment, how to do that depends on the DE and is probably described in the ArchWiki as well.

  • use ln -sf /etc/systemd/system/autologin@.service /etc/systemd/system/getty.target.wants/getty@tty1.service to overwrite it. Nov 9, 2019 at 14:23

Directly modify the file /etc/systemd/system/getty.target.wants/getty@tty1.service (which is a symlink to /lib/systemd/system/getty@service):

Append -a/--autologin USERNAME to the line:

ExecStart=-/sbin/agetty --noclear %I $TERM


ExecStart=-/sbin/agetty -a USERNAME %I $TERM

You might also remove -o '-p -- \\u' (as present on the current Arch installation) as this would start the login for USERNAME but still asks for the password.

After rebooting, you will be logged in automatically.

P.s. Change the filename getty@tty1.service to the tty you want to log into.

  • Note for clarity: if it's a symlink, replace the symlink with a new file, and edit that new file. Dec 4, 2016 at 4:28

IMO, the Arch Wiki currently recommends a much simpler solution:

Either run the helper (systemctl edit getty@tty1) or do what I did manually:

mkdir -p /etc/systemd/system/getty@tty1.service.d/
touch /etc/systemd/system/getty@tty1.service.d/override.conf

The text you want to enter (by either method) is (be sure to change username appropriately):

ExecStart=-/usr/bin/agetty --autologin username --noclear %I $TERM

NOTE: The empty line is important! The empty line will first clear the ExecStart entry, while the next line will introduce a new exec command.

Now, restart (shutdown -r 0) and something to the effect of ... login: username (automatic login) will happen where it previously blocked waiting for username/password input

Once rebooted, and auto-logged in, if you're like me and want to SSH into this system now, you probably need to run:

systemctl enable sshd.service

Which will create the symlink (e.g. ln -s '/usr/lib/systemd/system/sshd.service' '/etc/systemd/system/multi-user.target.wants/sshd.service')

  • The arch wiki also mentions that if you still want it to require a password, but you don't want to type your username, replace --autologin username with --skip-login --login-options username

You can also use getty (get tty) command which allows you to auto login the specified user automatically, the argument of the getty can be either --autologin or -a, I am running Linux Debian Ubuntu so I don't know if this command is available in other distros.

getty -a <user>
