16.04 LTS installation, probably after installing updates, now unable to start Unity after user login. It just freezes!
Google'ing won't help this time :/
I.e. OS boots, show login screen, but Unity hangs during startup and never finished it. I'm even unable to switch to the another console, system does not respond.
How to debug such kind of problems? What can i do to repair system?
I don't want to reinstall it - so Windows way it is :(
