*   [Display manager](/index.php/Display_manager "Display manager")

[nodm](https://github.com/spanezz/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 [[2]](https://github.com/spanezz/nodm/issues/8).

## Installation

[Install](/index.php/Install "Install") the [nodm](https://www.archlinux.org/packages/?name=nodm) package.

## Usage

Now ensure no other display managers get started by [disabling](/index.php/Disabling "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!

 `/etc/nodm.conf` 
```
NODM_USER=*user*
NODM_XSESSION=/home/*user/.xinitrc*
```

[Enable](/index.php/Enable "Enable") `nodm.service` so *nodm* will be started on boot.

### Login session

For proper session handling, create pam.d file with the following content:

 `/etc/pam.d/nodm` 
```
#%PAM-1.0

auth      include   system-local-login
account   include   system-local-login
password  include   system-local-login
session   include   system-local-login
```
