root@pc220hh2:~# for i in 1000 101265 101125 101139; do gdbus call --system --dest org.freedesktop.Accounts --object-path /org/freedesktop/Accounts/User$i --method org.freedesktop.DBus.Properties.GetAll org.freedesktop.Accounts.User|sed -e 's/),/),\n/g;s/>,/>,\n/g'|grep SystemAccount; done 'SystemAccount': <false>, 'SystemAccount': <false>, 'SystemAccount': <true>, 'SystemAccount': <false>, But why? I will attach the full info for this user. ** Attachment added: "accounts-daemon info for user 101125" https://bugs.launchpad.net/ubuntu/+source/accountsservice/+bug/1290785/+attachment/4143755/+files/accountsservice-user101125 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1290785 Title: Users with UID > 60000 are invisible in login and Settings->User unless /etc/login.defs updated To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/accountsservice/+bug/1290785/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
