I forgot to mention: sometimes it takes two or three "sudo service lightdm restart" attempts before the system proceeds normally. In other words, it will bootup, go to the blinking cursor, I'll restart lightdm, and it will go to the blinking cursor again. Sometimes if I'm fast, I can catch it starting to load the lightdm greeter screen for a split second before it crashes.
