http://unix.stackexchange.com – Lightdm is displayed properly but after entering a password and clicking login, I see the screen blink and lightdm window re-appears and asks to log in as if nothing happened. Configs user@laptop:~$ cat /etc/lightdm/ lightdm.conf lightdm-gtk-greeter-ubuntu.conf lightdm-gtk-greeter.conf users.conf lightdm.conf user@laptop:~$ cat /etc/lightdm/lightdm.conf #[LightDM] #xsessions-directory=/usr/share/xsessions [SeatDefaults] user-session=xfce greeter-session=lightdm-gtk-greeter greeter-hide-users=true lightdm-gtk-greeter.conf user@lap (HowTos)
