I seem to be having some odd lightdm behavioral issues. So far this what I have in my /etc/lightdm/lightdm.conf file:


How I'd expect lightdm to behave based on the above is the means to type in a username, list of available users hidden and the guest account not available. However all I get is as follows:

enter image description here

I've read on these forums and elsewhere that unless greeter-session is set to lightdm-gtk-greeter the options in my lightdm.conf file will not be honored.

However, if I make the changes accordingly then reboot, all I see is as follows:

enter image description here

I'm running 12.04.2 within a VM.

Any help would be greatly appreciated.

Thanks in advance, Dan.

UPDATE: I didn't realize that lightdm-gtk-greeter was a package. Once I installed the it, I was able to avoid the low-graphics issue, however, there's been a misunderstanding on my part. I also didn't realize that by specifying lightdm-gtk-greeter it would display the old gnome greeter. I want the unity greeter. For clarity, even with the gnome greeter, i was still unable to enter usernames etc. Seems no matter what i do, i get the same un-desired affect with both the gnome and unity greeters. – DJC Mar 16 '13 at 13:09
ANOTHER UPDATE: I'm going through the process of elimination in an attempt to resolve this but now I'm even more confused than ever. I set greeter-hide-users=false so I was expecting to see some users within the greeter and although that was the case, I can now also see Login option! If I select Login, it immediately asks for a password (no username option). Totally confused!!! Can anyone confirm whether this behavior associated to a bug? – DJC Mar 16 '13 at 15:10


Transpired that the issue was nothing to do with lightdm. An application had been installed that made some custom changes to the /etc/pam.d/lightdm and /etc/pam.d/lightdm-autologin files. I restored them to their defaults and the issue was resolved. I'm now seeing exactly what I was expecting. I hope I've not upset the application in question too much by doing do:-)!!

Thanks to those who bothered to take the time to read this post!
