You probably didn't set everything up correctly.

It is not safe to remove checks for DRM_MASTER. The master is the application that controls the displays – i.e. your compositor. Regular applications should not be allowed to execute the same calls.

Are you sure sway is using CK2? I think there's a verbose flag to sway that shows a lot more info. Did you actually install wlroots with the consolekit option?

You can use dbus-monitor --system to inspect dbus messages, if you don't see CK requests from sway, it's just not trying to use it.

wlroots likes to just silently try the next available backend, so if it can't do CK, it goes to try direct.
