Been trying all the different answers out there about this issue and still have nothing working. I ran the updates today, April 5th, and upon rebooting I started getting this error. I'm running on an Asus ultrabook (Intel graphics) so none of the nvidia/ati "solutions" really help. Someone mentioned downloading the repos for the unstable intel drivers but that doesn't work either. Nothing seems to help recover the system. Is there anything special to be done for Intel graphics computers that will help here?
Other things I tried:
- reinstalling lightdm
- removing all nvidia files and reinstalling them
