I have auto login enabled, and I just upgraded to 11.04. When I boot, I get a message saying that I don't have the hardware required to run Unity, so I should choose Ubuntu Classic at the login screen. The problem is that auto login bypasses the login screen, and I can't disable auto login via the normal route since I can't start xwindows.
I have a Ubuntu 12.04 and have removed the GUI essentially making it a server. I have been trying to figure out how to turn off the auto login on the tty1 command line that it boots too. The other consoles do not have auto login setup.
When installing 11.2, I chose not to enable auto-login during the install process. I have now tried to enable it through the System Settings menu, but the changes do not take effect. I've checked and rechecked and restarted numerous times, but still auto-login will not enable. I've also tried changing the login splash screen, but upon reboot, nothing has changed.
Anyone have any ideas?
Does auto-login/passwordless login leave the computer in exactly that same state as it would be after manually logging in, or does it create security risks of a type other than physical access control? I understand there are many ways to accomplish auto-login. If it makes a difference for this answer, I'm referring to doing it via settings in the KDM login manager. (Debian Wheezy)
