I recently updated to 15.10, and now when I boot up, It gets stuck on "Starting light display manager" part of the boot sequence.
I've purged and installed xorg, lightdm, nvidia drivers, all about a hundred times. I've also looked everywhere online looking for solutions, but no success.
I have an Nvidia GeForce 750 card, and I've tried installing almost all the drivers from either their site or from aptitude.
How can I debug/fix this?
