I previously posted details on how to setup Fedora Core 9/10/11 for auto login. Well I’ve recently downloaded and install Fedora Core 12 on my mythtv server and it still works. Here’s how to do it:
Edit /etc/gdm/custom.conf and add this to the file. You could use gedit or vi whatever suits you, but you need to do it as root.
Obviously you would replace “username” above with the actually “username” you wish to login automatically.
Now reboot and test it!
