I had exactly the same problem - same icons missing as well. I had stupidly uninstalled gnome-bluetooth, and nothing was fixing it. So I did what user282306 (r00t) suggested - sudo apt-get install ubuntu-desktop And I've got them all back again. Kudos @user282306 (previously r00t) for the suggestion. My pronouns are He / Him

I didn't want to re-install the whole ubuntu-desktop because it was going to install a bunch of packages I didn't want/need and use another 100MB of space. Compared to just 4MB with unity-control-center

Second, by default xclip selects XA_Primary buffer rather than the XA_CLIPBOARD. So you should pass clipboard as the selection parameter for xclip. Change your hotkey command to the following: ...
