Please tell me what to do to get the indicator.

Try running these commands:

gconftool-2 --set "/apps/nautilus/preferences/show_desktop" --type bool true 
gconftool-2 --set "/apps/gnome-screensaver/idle_activation_enabled" --type bool true

And try to run indicator-displex again.

Thanks, it worked. But what do those commands mean (specifically the second one) –  Siva Prasad Varma Mar 9 '12 at 3:21
    
I simply googled the last line in your error message.. That led me to this question, and one of the comments by Schubibuntu held the answer. Apparently, indicator-displex depends on those two Gconf (Gnome Configurator) values to launch, but they don't seem to be initialized properly. Running the above commands initializes the values and allows the app to launch. What the two settings actually do can be found here, or with a quick Google search ;) –  SirCharlo Mar 9 '12 at 13:32
