How to automatic login into arch linux
1. cp /usr/lib/systemd/system/getty@.service /etc/systemd/system/autologin@.service 2. ln -s /etc/systemd/system/autologin@.service /email@example.com 3. change the line in /firstname.lastname@example.org : ExecStart=-/sbin/agetty -a USERNAME %I 38400 4. restart the deamons: systemctl daemon-reload systemctl start email@example.com 5. ~/.bash_profile (taken from the wiki again): if [[ -z $DISPLAY ]] && [[ $(tty) = /dev/tty1 ]]; then exec startx fi This is described in the Arch Wiki: 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 modifed. 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 /firstname.lastname@example.org` 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 email@example.com (I'm not sure if the service will start properly if you're already logged in on tty1, the safest way is propably 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 fi 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 Arch wiki as well.
