11.04gnomeindicatorunity
Since I heard that indicator applets are going to replace the notification area, I wondered what was going to happen to applications that use the notification area and don't have an indicator applet?
Is the Ubuntu team going to write an indicator applet for every application out there?
You can't expect the developers of applications to add that Ubuntu-only task to their list.
Don't get me wrong, I love the indicator applets. But I'm a little concerned about this.
There is an option in Network manager not to use password. If you edit the connection, at the bottom of the page there is a box "available to all users" if you tick this it will not require a password.
To edit right click the icon, select edit Connections, select wireless,select your connection and click edit.
From Ubuntu 13.04 onwards you have to whitelist the applications if you want to allow access to the system tray.
Firstly install dconf-tools from the software center ( or by clicking here)
Then Press Alt+F2 and enter dconf-editor and run it.
Now navigate to Desktop -> Unity -> Panel.
Now change the value of systray-whitelist to
"all"
Note that setting this to "all" will likely lead to other bugs, as the old notification area is unmaintained, instead consider adding applications you need individually instead of just enabling everything. You can reset it to the defaults by checking out this question:
Do note that the system tray is entirely removed in 13.04 and newer and that older applications that still have not been ported need to be updated:

We've been working on a transition plan for a while now. The desktop team put together a list of applications that are affected by the transition and people have started to post design recommendations, filing bugs, and fixing applications. Any help talking to application developers of your favorite applications is always welcome!
KDE applications all work (application indicators are based on the same KSNI technology) and everything we ship on the CD is ported. Many applications are also just porting to the technology on their own. Application Indicators specifically have a fallback mechanism in place so that application authors can use them without having to break on systems that use the old notification area.
In Unity when I use an application that doesn't use application indicators remember that the icon for the application is sitting in the launcher too, so it's not like it totally disappears from your view, it's just not sitting in the top right of the panel.
For 11.04 there is a whitelist for applications that need to use the area. Users can modify this list to add legacy apps if they require it.
(Omar has information on what will happen to other apps.)
