I've been running this machine for some time (a year or so), and this morning when I went to boot up, the boot stopped with a black screen and a flashing white cursor.
After a few attempts at a boot (and successfully booting into windows to make sure my hardware wasn't fried), I got into the root console through the "recovery" boot option.
I emailed myself the lightdm log files:

About my setup:
I run an Nvidia graphics card, and Mate Desktop (although I still use the lightdm greeter). This problem is occurring before the greeter shows up, so most of the system is booted, but the only way I can get into is is via the root console in recovery mode, or via SSH from my laptop.
After a few attempts at a boot (and successfully booting into windows to make sure my hardware wasn't fried), I got into the root console through the "recovery" boot option.
I emailed myself the lightdm log files:

About my setup:
I run an Nvidia graphics card, and Mate Desktop (although I still use the lightdm greeter). This problem is occurring before the greeter shows up, so most of the system is booted, but the only way I can get into is is via the root console in recovery mode, or via SSH from my laptop.
