In the examples below, changing an Xconfig resource changes the login screen behavior for all displays. The resources listed with an * (asterisk) can be specified on a per-display basis. This enables you to specify custom login screen behavior for certain displays. To specify a resource for a particular display, the resource is specified as Dtlogin*displayName*resource. For example, if you would like to turn off user based access control for display expo:0 but leave it on for other displays, you would specify:
Dtlogin*expo_0*authorize: False
Any special character in the display name, such as a : (colon) or . (period), is replaced by an _ (underbar).
