Window Managers - page 2
TWMTWM has been around since the early days of X Windows and is very basic. On the plus side it is light on memory and CPU use. It is also standard with all the distributions as a kind of baseline. On the minus side its applications framework is almost nonexistent.
AfterStep http://www.afterstep.org/If you liked the look of the NeXTStep user interface then AfterStep could be the choice for you. Even if you haven't things like its 'Wharf' free floating application loader that can "Swallow" running programs and its carefully designed set of consistent icons may make this the one for you.
Blackbox http://blackbox.wiw.org/Blackbox is designed to be a very small window manager light on disk space, memory use and CPU use.
Enlightenment http://www.enlightenment.org/After Describing what a window manager is ( see above ) the Enlightenment web page says:
"Enlightenment goes beyond this[ being a window manager], not just Managing Windows, but providing a useful, good looking graphical shell from which to work. It is open in design, and instead of dictating a policy it allows the user to define their own policy right down to the minute and infinitesimal details; from its functionality right on through to its looks.
Enlightenment is IN DEVELOPMENT and as a result its stability can vary from day to day in snapshots. One thing you can be certain of is that it DOES work - the developers run it all day themselves - There is a reason it doesn't work for you - it is likely something on your system."
