Q:

Can the network indicator be hidden? 

Using 11.04.  The network indicator is visible at all times, but this isn't necessary for me, it just adds clutter.  Is there any way to hide/remove it? 
Thanks! 

A:

The simple answer is no, the indicators cannot be individually enabled or disabled, however you can kill the network indicator by running the following command: pkill nm-applet
To restart the network indicator, run nm-applet
To turn off the network indicator so it doesn't show up at all when you log in:

Click the power icon in the top right corner and select System
Settings. 
Click Startup Applications in the Personal section. 
Uncheck the Network Manager item. 

Be aware that killing the network indicator will not allow you to connect to wireless networks.
