I was able to reproduce the problem just a moment ago. I have attached a copy of /var/logs/lightdm/lightdm.log in the state it was in immediately after I was unable to get to a login screen. Perhaps the following line from the log file is the problem?
0.60s] DEBUG: Failed to load session file /usr/share/xgreeters/lightdm-gtk-greeter.desktop: No such file or directory
I just checked; it would seem that file is present on my system though.
I am not sure which libraries are relevant, so I will wait and see if you need to know more. I am happy to supply any needed information though.
@bdheeman, thanks for responding.
