I ran into this a few times at work on a few systems. On a hunch I
just moved .config to a new location and then tried to log in to the
GUI like normal. This process causes Unity to reset to defaults, but
it at least gets the system working again as it generates a new
.config directory on the fly (at least in my experience).<br>
<br>
At login screen on a fresh boot:<br>
<br>
CTRL ALT F1<br>
log in to TTY<br>
mv .config .config-OLD<br>
exit<br>
CTRL ALT F7<br>
log in to GUI<br>
<br>
Given that you are doing a move (mv) and not just nuking the
directory, it should be easy to reverse if need be. <br>
<br>
Next time this comes up at work I intend to dive further into
.config to see what exactly I can remove so I don't have to move the
entirety of .config, but as of now that's the best idea I have in
mind.<br>
<br>
Hope this helps!<br>

<div><br>
</div>
<div>Yesterday I found I couldn't log in Ubuntu 15.10 on
my laptop. Every time when I enter my login password,
the screen just flashed and went back to login screen
again. I don't think I did anything specially before.
I didn't update Ubuntu recently. Ubuntu worked very
well in past days. </div>
<div><br>
</div>
<div>I tried several solutions in Ubutun forum, e.g.
change the access right of ~/.Xauthority, but they
didn't work. The ~/.xsession-errors file is empty. I
cannot figure out what is wrong with my Ubutun. I'll
appreciate if anyone can help me.</div>

<div>Thanks.</div>
