First login with the CLI, press ctrl+alt+f1 or f2 then login with your user then try below steps,

found this bug here:

Specifically you have to place .rule file here,


(add a filename and just give the .rules extension)

give below rules:

polkit.addRule(function(action, subject) {
   if (( == "org.freedesktop.color-manager.create-device" || == "org.freedesktop.color-manager.create-profile" || == "org.freedesktop.color-manager.delete-device" || == "org.freedesktop.color-manager.delete-profile" || == "org.freedesktop.color-manager.modify-device" || == "org.freedesktop.color-manager.modify-profile") &&
       subject.isInGroup("username")) {
      return polkit.Result.YES;

Then you have to Replace the word "username" with your user's group.
