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.
Best,
