This is a modification of the lock/logout plasmoid. It's for those like me, who just need the logout button on the desktop or panel.
- untar the archive
- cd ~/logout
- mkdir build
- cd build
- cmake -DCMAKE_INSTALL_PREFIX=`kde4-config --prefix` ..
- make install (as root)
All credits should go to the plasma-team, because I've just edited and deleted a few lines of code.
