I am not able to adjust any of the settings in Ubuntu 14.04. Everything in Unity is locked/disabled. I've tried uninstalling Unity and reinstalling it. I've tried installing xscreensaver and that did not work. The PC would suspend and then lock after 5 minutes.
Then I tried opening unity from the terminal and when trying to change the lock settings this showed up… I have no idea what this means but maybe someone a little more knowledgeable can discern what it says and hopefully help me fix the problem?
