Hi all,
my problem seems to be similar to this: http://www.ubuntuupdates.org/package...ettings-daemon
Version: 3.4.2-0ubuntu0.6.2 2013-01-30 18:06:58 UTC
but I do not use smartcard authentication - just common username/password.
It fails with any user - I have 4 - with different DM : Gnome-classic-with-no-effects, Gnome-classic, Gnome, Unity .
I am able to go thru the first one only - via manual startinit xinit and gnome-session -f and even this one crashes but X-windows survive so I can send the event by the ubuntu crash collector (and also write this thread.

some date:

I am about downgrading “gnome-settings-daemon" to 3.4.1 But I prefer some more sophisticated solution.

Can anyone give any suggestion?

PS. I tried also the lightdm but result was quite similar: I can sign in but after some seconds of invisible activity the login screen re-appears.
