As you may not I’m a big fan of mythtv and I want to have Fedora Core 9 (it’s works for 10 and 11 too) login automatically when the PC is booted up.
For some reason on Fedora 9 gdm is different and you can’t easily configure it to auto login through the GUI, but here’s another way.
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!
