Another possible problem is a change or misconfigured hostname.
Some time in the last ~5 years, some bright mind somewhere made 'localhost' an illegal hostname in a display manager helper program (never did figure out how far down into the display manager called/child path it was). If this is the cause of your issue, change your hostname in ‘/etc/hostname’ from ‘localhost’ to something else and reboot.
