Ubuntu hangs on Starting light display manager on bootup

Question

I've been going at this for about 10 hours, and I can't find a solution to this problem.

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.

Can I please get assistance?

Thanks!

Answer 1

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

Answer 2

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.
