How about simply reinstalling your dm?  Or trying installing a different dm?

Since you're going to reinstall, set up the system to boot to a
terminal, the login and run startx, and see what happens.  If all goes
well, then change your init config file to boot to the GUI instead and
see if all works.

If you have problems with X, at least, you'll be able to login to the
system and troubleshoot.

Sorry, X is probably crashing! If the display manager was crashing you
wouldn't be able to log in :)

Well, whatever. I tried a couple of things and now I get 
nothing on my screen at all!


I guess I will reinstall tomorrow instead of next week. I'm

Thanks for the efforts guys, appreciate it!

I would say that the user's X session is crashing, not the display
manager. Assuming a default jessie setup , the command

journalctl /usr/bin/gnome-session

(run as root) might yield some useful diagnostic information. The file
/var/log/Xorg.0.log might be helpful too.

The display manager is most likely crashing. You need to examine logs
and figure out why.

Check the files in /home/$USER are not owned by root. They should be
owned by the user. If any hidden files are owned by root, the GUI login
loops.
I would not expect this to be the problem, as OP stated that he could 
also not log-in with GUI as root either...hidden files in the /root 
directory should be owned by root in this situation.

Also check if any partition is full. Running out of space can cause
this.
I did run across this once as well.  The partition that /var is on is a 
prime suspect:-)

These are the things I have found. Perhaps someone else will jump in
with more information.

I have had similar situation before.  I can't say that this is a good 
much less the best way to deal with it, but what I ended up doing is 
deleting all of the configuration files stored in the home directories 
of the affected users.  (anything starting with .)  Once this was done, 
the desktop environment was forced to re-create new configuration 
files.  This problem, in my experience is due to something in one of the 
configuration files that was corrupted.  In your situation, as it 
affects more than one user, this may not work as it it probable that the 
problem is in a global configuration in the /etc directory.  Hopefully, 
someone with more experience will answer and give you a better pointer 
to exactly which files to look at.

I fill in user-id and password, click "Sign In" and the 
screen goes blank, flashes a few times, then comes right 
back to the sign in screen. Trying to log on with root does 
the same thing, even though I am supposed to be able to do it.
