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?

I have the same problem, but with an AMD card. I've found a work around by going into the console with

ctrl alt f1

sudo apt-get install xinit

then using the command

startx unity

I found a solution to the problem here Ubuntu 15.10 boot hangs when starting Lightdm

Sound support was disabled in the BIOS of the machine for me. Hence, no driver worked. This happened because I loaded the failsafe settings in the bios while trying to get the machine to boot via floppy, CD and USB. However, once I loaded the optimized defaults in the BIOS settings, everything worked fine.
