KDE and GNOME combine window managers with suites of applications to create comprehensive work environments. As complete as they are, it’s easy to forget that there are other graphical ways to work on a Linux desktop. Sometimes a lighter-weight window manager is in order, such as for laptop usage, children’s use, or quick startup applications. Here are four “alternative” window managers that are mature, fast, and functional. My Take: Should we also add *Box, WindowMaker and XFce to the mix?
