Fedora如何实现自动登录

To set up Fedora to login automatically just open the file /etc/gdm/custom.conf, and then add the following three lines
to the end of the file.

[daemon]
AutomaticLoginEnable=True
AutomaticLogin=brad

In the above brad is my user name. Obviously you should use the user name you want to log into automatically.
An alternative method is to login automatically after a certain amount of time. To do this use the following four lines.

[daemon]
TimedLoginEnable=True
TimedLogin=brad
TimedLoginDelay=5

The TimedLoginDelay option is used to set the number of seconds to wait until the user is automatically logged in.
