LightDM Auto Login

From Manjaro Linux
Jump to: navigation, search

Overview

Note: LightDM has been replaced by LXDM from Manjaro 0.8.1 onwards. This article also requires expansion.

Manjaro 0.8.0 uses a lightweight display / login manager called LightDM by default. LXDM is responsible for providing the login screen. It also functions as a protective security barrier to prevent unauthorised access to your system. However, some users may prefer to bypass the login screen to boot straight into their desktop environment without entering a password.


Open the LightDM Configuration File

The syntax the command to edit the LightDM configuration file is:

sudo [text editor] /etc/lightdm/lightdm.conf


To use nano (the default text-based terminal editor) enter the command:

sudo nano /etc/lightdm/lightdm.conf


Otherwise, you may find it easier to read and edit the file by using gedit, which will open the configuration file as if it were a document. To use gedit instead, enter the command:

sudo gedit /etc/lightdm/lightdm.conf


Set Autologin

Find the following codes in the configuration file:

session-wrapper=/etc/lightdm/xsession
............
#display-setup-script=
#greeter-setup-script=
#session-setup-script=
#session-cleanup-script=
#autologin-guest=false
#autologin-user=
#autologin-user-timeout=0
#autologin-session=UNIMPLEMENTED

Delete the '#' from the following line as shown below, and add your username to it:

session-wrapper=/etc/lightdm/xsession
#display-setup-script=
#greeter-setup-script=
#session-setup-script=
#session-cleanup-script=
#autologin-guest=false
autologin-user=[your username here]
#autologin-user-timeout=0
#autologin-session=UNIMPLEMENTED
Example: A user called yfdogan would chance the line to: autologin-user=yfdogan

Once your amendments have been completed save your changes and close the configuration file by:

  • nano: Press CTRL and 'x' to exit, 'y' to save, and <enter> to finish, or
  • gedit: Select the 'save' option and then close the window.


Reboot your system for the changes to take effect.
