Well, similar experience for me today, booted and logged in okay, but
then the desktop session died leaving monitor backlight and keyboard
lights on, but no other sign of life. Shutting lid to suspend then
resume didn't help, had to hard power off. Then on next boot, it hung
after login, but recovered and was fine thereafter. More oddness, but
not the gpu in the blame this time.


Log sequence extracts:

Full logs in attachment. Feels like this has to be more than one issue, though 
perhaps the worst symptoms all have a common root cause.
