I have installed a fresh Ubuntu 14.04 Desktop system. I haven't configured anything yet. Thus, the very first action was to start the unity-control-center by clicking on the gears icon. Then, I clicked on the "all settings" button but it has no effect. Instead, I expected more settings options to appear.
When I start the program on the command line, it does not print any error messages.
unity-control-center
, so you are actually on the "All Settings" menu. You should upload screenshoots to explain better.
