I enabled autologin in my system (CentOS 6.2) for that I edited this file /etc/gdm/custom.conf In that I entered this code

[daemon]
AutomaticLoginEnable=true
AutomaticLogin=test

Here test means one account name, for that account autologin is working but the problem is not possible to logout. That is because everytime while I logout it will go to gdm(graphical display manager) and there it Again checks for account test. It is available right so it will again login to same account.

Here I want add delay, that means it should wait for sometime, If no one login to any other account, then only test account will log.

how to add delay?
