I know that I’m the only user in my system and no one else will have access to it. I don’t see a point to have a login screen. With Windows, I know we can set to auto login using a userid. I was searching for similar thing in Ubuntu. Found one
Go to terminal and type “sudo gdmsetup”. You will get login window preferences. Select Security tab; check “Enable automatic Login” and select the user. You are done! Simple ha? But why there is no shortcut in the Preferences/Administration/Applications menu?
