I installed DockbarX on ubuntu 10.04 using following command:
$ sudo add-apt-repository ppa:dockbar-main/ppa
$ sudo apt-get update && sudo apt-get install dockbarx
but dockbar is not showing up, do i have to do something to enable it.
EDIT
I want Dock to replace the whole panel.
Currently I am getting this look,

but i want this kind of look

System -> Preferences -> DockbarX Preferences(could be administration, I forget) and start tweaking with the settings there. – digitxp Feb 7 '11 at 12:07
