How were you able to get a user logged in to both seats? I thought that the password prompt issue only made it possible for one user to be logged in at a time. Are you doing auto-login? > second seat turns black and has black cross instead of standard > mouse pointer. With X, user switching is only supported on the main seat (seat0). LightDM currently doesn't ask logind if the current seat supports user switching; it just assumes that it does. So trying to switch users on the second seat will do weird things. Ideally you wouldn't even see the menu option to switch to another user if you're not logged in on seat0. I have a patch that partly fixes this, but breaks other things. I'll finish it up after basic multiseat support has been merged to LightDM. > *) 'udevadmin info --export-db' showed only one record with > 'master-of-seat' tag. So I added line 'TAG=="seat", > DEVPATH=="/devices/pci0000:00/0000:00:1c.0/0000:02:00.0/*", > TAG+="master-of-seat"' back to 99-multiseat.rules.

The default setup is the common setup. It becomes uncommon the instant you add or remove a PAM module. There are PAM modules to do all sorts of stuff related to user authentication. For example, there are PAM modules to lock out users if they fail to enter their password more than X times in a row, PAM modules to require new passwords to match certain rules (e.g., not a variant of a dictionary word, more than X characters long), PAM modules to require two-factor authentication (e.g., <https://code.google.com/p/google-authenticator/>), etc. It may help to post the relevant PAM config files: * /etc/pam.conf * /etc/pam.d/lightdm* * /etc/pam.d/common-* * /etc/pam.d/other I can then compare them to my PAM config files to see if there's any difference. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/976124 Title: lightdm multiseat: no login possible To manage notifications about this bug go to: https://bugs.launchpad.net/lightdm/+bug/976124/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
