This happened a few times in a row, but it had not happened the previous time I'd run lightdm, and it didn't happen any subsequent times. (I'd recently stopped and restarted the lightdm service, and I did that again to overcome the problem; then the greeter worked and I was able to log in.) I discovered soon afterwards that unity-greeter had crashed. I presume this corresponds to one of the times lightdm quit as I started to enter my password. In case it's relevant, I'd previously logged into a Unity session. This system has old hardware--an Nvidia GeForce 5200 graphics card. The screen had flickered yellowish, then went to black. There was no visible interface. I restarted lightdm to get back to the graphical login screen. Please note that this is a description of the events that led me to run "sudo stop lightdm" followed by "sudo start lightdm" the first time, leading to a state where unity-greeter crashed. I'm not sure if the problems I had with Unity itself are relevant, and I understand they are probably not since unity-greeter is not really related to Unity except in that it is themed similarly. Please note that this bug report is for the unity-greeter crash and *not* for the graphics issue.
