OSResources - Unix, Linux and BSD Guides

It is possible to bypass the login screen in GDM, Gnome's Desktop Manager, so that you're logged in without having to type your username and password all the time. This is handy for computers that you use for test, at home for instance. To do so, open /etc/gdm/custom.conf as root and locate the [daemon] section. Underneath, just paste the following two lines of code where my_username is the username you want logged in automatically:

AutomaticLoginEnable=true
AutomaticLogin=my_username

Save. The next time you start your computer, you'll be automatically logged in :)
