Thanks to the hint from Robert, I finally found a solution for my user to be listed again:
There actually seems to be a method for setting the account type in the interface of org.freedesktop.Accounts.User, namely 'SetAccountType(in i accountType);' but I could not find a list of valid values for accountType. So I just uncached and then (re-)cached the user: gdbus call --system --dest org.freedesktop.Accounts --object-path /org/freedesktop/Accounts --method org.freedesktop.Accounts.UncacheUser euhus () gdbus call --system --dest org.freedesktop.Accounts --object-path /org/freedesktop/Accounts --method org.freedesktop.Accounts.CacheUser euhus (objectpath '/org/freedesktop/Accounts/User101125',) Now the 'SystemAccount' property is set to false and the user is shown in the login window. But I still have no idea, why this account was ever marked as system account. What stil remains to be done is release a fix for the currently stable (and even LTS-) release. P.S.: to find out about the available methods etc. I used: gdbus introspect --system --dest org.freedesktop.Accounts --object-path /org/freedesktop/Accounts --recurse | less -- 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
