I had evidently forgotten this was the case and the policy is set in
/usr/share/polkit-1/actions/org.freedesktop.login1.policy.

Once polkitd is installed this error goes away for me and libseat uses the
elogind backend correctly. I can switch VTs and on return inputs are still
available.

With polkitd installed does that work for you?

Do you have apt install recommends disabled?
