Configure automatic login
A user with an Administrator account type can panel. You can also set up autologin manually in the GDM custom configuration file, as follows.
Edit the /etc/gdm/custom.conf file and make sure that the [daemon] section in the file specifies the following:
[daemon] AutomaticLoginEnable=True AutomaticLogin=username
Replace the username with the user that you want to be automatically logged in.
The custom.conf file can usually be found in /etc/gdm/, but the location may differ depending on your distribution.
