In order to better be able to administer my workstation which is used by the entire household I have set up one administrator account and took away administrator privileges for all the others. However there was a problem with administering the linuxbrew packages already installed on the system and so I disabled the account.
But instead of booting into the greeter the system boots straight into the disabled administrator account. That is a major security flaw. do you have any ideas how to rectify that and make Elementary boot directly into the greeter?
