[Bug 1782510] Re: lightdm automatically logs in after logout
This defect may not be in lightdm package. I was just able to reproduce it on Ubuntu 18.04.01 distribution. Here is how I did it. I am using 18.04.01 with KDE. I installed the skypeforlinux package This package had unsatisfied dependency gnome-keyring as without it skype will not log in automatically. I installed gnome-keyring and seahorse so that I can reset the keyring. After these three I wasn't able to logout from my KDE session as I was logged back in. It didn't help to uninstall skypeforlinux or seahorse. Only after I uninstalled gnome-keyring and restarted my computer I am able to normally logout from my KDE session. On a side node now even after I log out, I can still see my session hanging around using sudo loginctl If I log in it till create second session as reported by the above command but at least I can logout reliably. ** Also affects: lightdm Importance: Undecided Status: New ** Also affects: gnome-keyring Importance: Undecided Status: New ** Also affects: skype Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782510 Title: lightdm automatically logs in after logout To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-keyring/+bug/1782510/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

After the second login, the session is not comlete, e.g. groups from pam+ldap are missing. Also the default KDE Wallet is not opened upon the first successful login. sddm works as expected. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782510 Title: lightdm automatically logs in after logout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1782510/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

To add further information. This is on multiseat system. Lately (~2 weeks) the system also started misbehaving where only one of the sessions can login reliably. THe other session login doesn't affect the Enter button to submit the password and start the session -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782510 Title: lightdm automatically logs in after logout To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1782510/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
