nodm is an automatic display manager which automatically starts an X session at system boot. It is meant for devices like smartphones, but can be used on a regular computer as well, if the security implications are acceptable.
The author is no longer continuing to develop, and has expressed a plan to replace it with a lightdm autologin wrapper .
Install the package.
Now ensure no other display managers get started by disabling their systemd services.
After installing nodm, modify the
/etc/nodm.conf file. Set the
NODM_USER variable to the user which should be automatically logged in, and change the
NODM_XSESSION variable to point to the script that starts your session. The
NODM_XSESSION script must be executable!
nodm.service so nodm will be started on boot.
For proper session handling, create pam.d file with the following content:
#%PAM-1.0 auth include system-local-login account include system-local-login password include system-local-login session include system-local-login
