I just upgraded to Natty and am getting used to the new interface. I depend on blue proximity for locking my desktop when I leave my office. After upgrade I no longer see the icon in the panel area. I tested and It is working but I have no idea how to configure it now. How do I get the icon back and configure it?
Your problem is that the program doesn't show up in the notification area. Ubuntu natty has a whitelist for only some programs to show up. But there's an easy way to either re-enable the Systray for all applications or to whitelist a few applications you can't live without.
To enable the Notification Area (Systray) for all applications, run the following command in a terminal:
You can only whitelist a certain application if you want, by using the following command:
The above command includes the already whitelisted (by default) applications so you should replace "YOUR_APPLICATION" with the application you want to whitelist.
In Ubuntu 13.04 the systray-whitelist hard-coded so the above configuration change no longer works. Use this https://bugs.launchpad.net/unity/+bug/974480/comments/42 ppa and follow the instructions to enable the whitelist and set it to "['all']"
