Re: [orca-list] Odd question - installed gnome into ubuntu, and, it won't accept my login password

[John G Heim <jheim math wisc edu>]

Oh, shoot, I just realized many of the users I support had these exact 
symptoms after I upgraded their machines from ubuntu vivid to xenial. 
What was happening was that they were authenticating correctly but 
lightdm was failing to start the X11 session for them. So they were 
getting thrown back to the login screen and it looked like their 
password was not being accepted. A good way to diagnose this is to go to 
a character console and try logging in. That might be difficult in these 
days when orca and speakup don't play well together because of pulse. 
But you might try connecting via ssh if that is enabled. Or you can go 
to a character console and use some app on your phone as your screen reader.

Also, my end-users routinely report this same behaviour when they have 
run out of disk space. That almost never happens any more which is why I 
forgot about it. But it looks like it's not taking your password when 
what is really happening is that your X11 session is failing to start 
because it can't create files in your home directory for the session.

To fix the problem caused by the upgrade, what I had to do was to delete 
some X11 session and/or cache files from the user's home directory. 
Unfortunately, I can't recall the names of the files I had to delete. It 
was something like .Xsession-cache. I poked around in the home 
directories hoping to trigger my memory but I don't see them. We're now 
running zesty and I think the problematic files were deleted by the op sys.

I originally figured out which files to delete by checkying the logs. 
Even if you're running out of disk space, the reason why lightdm can't 
start your X session should be in the lightdm logs.




Running out of disk space is definitely one thing that causes this symptom.
