Ubuntu 19.10: 'Power Off' and 'Reboot' do not work from session manager

[Weston Hunter]

I'm not really sure which package/component is relevant here. I already posted this in AskUbuntu, but it seems as if it could be a bug, so I thought I would add it here as well.

I upgraded to 19.10. On the session manager login screen, the 'Power Off' and 'Restart' options seem to have no effect.

When I'm logged in as a user, the 'Power Off' command works. `shutdown now` also works fine.

I also tried a 19.10 virtual machine. It also has the problem where initiating 'Power Off' from the session manager screen seems to have no effect.

(I have seen other questions which sound related, but I don't think I'm in the same situation as those other users.)
