For a few days, a user has not been log in via xfce4 lightdm login screen. But only for example alarm kill the xfce4-session, after that it is possible to login. There is no problem for the user to login via remote ssh from another linux pc.
I reinstalled xfce4 and lightdm again, but without success.
I didn't change any configuration.
Does anyone have an idea what the error could be and where I can look for?
Thanks in advance
