With a clean Ubuntu 20.04 LTS Server running GNOME, everything is working fine when I physically log into the unit. But when I RDP into it as xfce4, the Restart, Shu Down, and Suspend button are all greyed out! The only button that is available is Log Out.

How can this be fixed so I can shutdown, suspend, or reboot via Remote Desktop?

This is still a problem in Linux Mint 22 (via xrdp, to access a Hyper-V VM). I found I had to apply the fix by FlawTECH found in here: https://github.com/neutrinolabs/xrdp/issues/2298 and this enables the shutdown option. It doesn't enable suspend, but I don’t need suspend in this case.

Essentially, create a file /etc/polkit-1/rules.d/50-xrdp.rules with the content:

polkit.addRule(function(action, subject) {
  polkit.log(action + ", " + subject);
  if (~["org.freedesktop.login1.power-off","org.freedesktop.login1.power-off-multiple-sessions","org.freedesktop.login1.reboot","org.freedesktop.login1.reboot-multiple-sessions"].indexOf(action.id)) {
    return polkit.Result.YES;
  }
});

I then rebooted, and can now log in via xRDP, and can shut down.

save this file as
