Public bug reported:
I logged into a Unity session on a Quantal i386 system with old hardware
--an Nvidia GeForce 5200 graphics card. The screen flickered yellowish,
then went to black. There was no visible interface. I restarted lightdm
to get back to the graphical login screen. Soon after, I found that
unity-greeter had crashed. I'm guessing that this is secondary to the
video incompatibility rather than the cause of it, but it is
specifically the crash in unity-greeter that I'm reporting here.
