What about creating a system group like "noguilogin" that accountsservice uses to determine whether a gui login is allowed and passes that as a flag via dbus with other requested user information. Then all other services that use accountsservice can refer to this when validating whether an X session should be allowed. Also, services that don't utilize accountsservice can just look for membership in the group.
Another option may be as simple as changing lightdm so there's a way to disable using accountsservice. Then you could edit users.conf as you normally would. Not pretty, but it gets the job done. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/857651 Title: Unable to hide users from login screen / user switcher Status in D-Bus interfaces for querying and manipulating user account information: Confirmed Status in “accountsservice” package in Ubuntu: Triaged Status in “lightdm” package in Ubuntu: Triaged Bug description: Users that I have appended to the 'hidden-users' field in /etc/lightdm/users.conf are not actually hidden.
