Six month later I have the same issue. I can't login as ordinary user rose with lightdm. It is an Ubuntu 15.04 for armv7l . At the beginning I saw the issues with kwallet, which is not installed. I commented out the corresponding lines in. I have now:
root@odroid6:~# cat /etc/pam.d/lightdm #%PAM-1.0 auth requisite pam_nologin.so auth sufficient pam_succeed_if.so user ingroup nopasswdlogin @include common-auth auth optional pam_gnome_keyring.so #auth optional pam_kwallet.so @include common-account session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so close session required pam_limits.so @include common-session session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so open session optional pam_gnome_keyring.so auto_start #session optional pam_kwallet.so auto_start session required pam_env.so readenv=1 session required pam_env.so readenv=1 user_readenv=1 envfile=/etc/default/locale @include common-password and root@odroid6:~# cat /etc/pam.d/lightdm-greeter #%PAM-1.0 auth required pam_permit.so auth optional pam_gnome_keyring.so #auth optional pam_kwallet.so @include common-account session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so close session required pam_limits.so @include common-session session [success=ok ignore=ignore module_unknown=ignore default=bad] pam_selinux.so open session optional pam_gnome_keyring.so auto_start #session optional pam_kwallet.so auto_start session required pam_env.so readenv=1 session required pam_env.so readenv=1 user_readenv=1 envfile=/etc/default/locale It seems that my password is accepted (login via ssh works perfectly), but with lightdm I get only a black screen with mouse cursor. Login as user odroid which is in group nopasswdlogin with lightdm works too. After trying to login as user rose, I have to login with ssh and kill all processes owned by rose. At the end of /var/log/auth.log I see: Oct 28 19:34:17 odroid6 lightdm: pam_succeed_if(lightdm:auth): requirement "user ingroup nopasswdlogin" not met by user "rose" Oct 28 19:34:26 odroid6 lightdm: pam_unix(lightdm-greeter:session): session closed for user lightdm Oct 28 19:34:26 odroid6 lightdm: pam_unix(lightdm:session): session opened for user rose by (uid=0) Oct 28 19:34:26 odroid6 systemd-logind[651]: New session c8 of user rose.
