Recently I started using Plasma activities, and I found it very useful and effective in my workflow. The only thing I missed in Plasma Desktop 4.6 is a fast and simple way to switch between activities and manage it.
Then I found a little plasmoid which can be put in the systray and does exactly what I need: the Activity Manager Plasmoid. It seems that it will be packaged in Kubuntu Natty, but I couldn’t find a package for Maverick.
Fortunately installing from source is very straightforward:
Install build dependencies
$ sudo apt-get build-dep plasma-widgets-addons
Download the source package Extract it somewhere:
$ tar xjf 136278-activitymanager-0.5.tar.bz2
Go in the source directory:
$ cd activitymanager-0.5
Configure with CMake:
$ cmake -DCMAKE_INSTALL_PREFIX=/usr .
$ sudo make install
Voilà, your shiny Activity Manager is now ready to be added to the system tray or your panel like any other Plasmoid.
