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 DX Packages, which is subscribed to accountsservice in Ubuntu.

This was not required in 12.04 LTS. In 12.04 LTS users were only hidden if they had UID < UID_MIN. In 13.10 this was changed to UID < UID_MIN or UID > UID_MAX. [Test Case] 1. Create a user with a UID > UID_MAX: $ adduser --uid 60001 big-uid 2. Restart system Expected result: "big-uid" is shown in the greeter. Once logged in "big-uid" is shown in system settings. Observed result: "big-uid" is not shown in the greeter (14.04 LTS, 14.10) "big-uid" is not shown in system settings (13.10, 14.04LTS, 14.10) [Regression Potential] This could cause users that were previously hidden to be shown. This seems unlikely to be a problem as all system created user accounts are less than UID_MIN and there doesn't seem be a convention to use accounts > UID_MAX for this case.
