Description

There are two icons in my window settings manager for my nvidia x-screen settings controls. One works (it is the correct path and command) and the other does not (it has gksu in the command, which is not part of Xubuntu 14.04).

I should be able to control which icons I want and which ones I don't, and edit the ones I have, but there is no way to do this that I can see.

I'm running Xubuntu 14.04 new install (fully updated) on a Phenom II x6.

Please fix or advise.

Thanks.
