Q:

Can I remove/ uninstall "Toggle Desktop"?

This is where I found out how to install it.
I tried sudo apt-get remove wmctrl but it did not work, even after reboot. I could not find anything on the Internet. 

It is the icon on the left, with the gears. Maybe there is a way to remove any of these icon (The Toggle Desktop)? Ones in the top bar? For the record I'm using Ubuntu 11.10

A:

This is the indicator author. To remove the icon from the panel you need only remove the app from "startup applications" as listed above. I personally use Ctrl+Alt+D to toggle the desktop. It is faster.
