Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I used to modify /etc/lightdm/lightdm.conf, adding the line greeter-show-manual-login=true, in order to allow login for hidden users and root.

Now I've just installed the new Ubuntu 14.04 and the file lightdm.conf is no longer located in /etc/lightdm. It's in /etc/init and has been totally modified.

How can I force lightdm login screen to show a field to input a login name?

Ok I finally found the solution, very simple. The file to edit is now located in /usr/share/lightdm/lightdm.conf.d, and is called: 50-ubuntu.conf.

I just added the line:


and on next reboot I was able to input any user name on the login screen.

Rather than editing a default system file, why not add your own to the lightdm.conf.d folder? – bshacklett Nov 26 '14 at 18:48

I also had the same issue with Ubuntu 14.04 installation. But I resolved the problem by following this site.

The solution is to create a file lightdm.conf inside /etc/lightdm/ and put the following contents in it:


After a system reboot, I was able to login with other users.

On the Ubuntu 14.04 64bit the configuration file changed to /usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf But on 32bit is same as before – user3597121 Aug 21 '14 at 15:30

Also you should do following step:

update /etc/pam.d/common-session and change the line:

session sufficient


session [success=ok default=ignore] pam_lsass.s

After a reboot, my path was ok, and everything seems to be working as normal again.

See the bug report
