Window Managers - page 3
Beware of Memory and Disk UseYou should be aware of the heavy memory and CPU utilization most of these window managers take. Linux will run quite fine on old hardware but something like KDE needs a modern machine with lots of RAM to run properly. They also use a lot of disk space with Icons, Themes and other graphical embellishments. On an older machine it is better to run something like FVWM, Window Maker or even TWM.
Links of InterestGNOME is the GNU Network Object Model Environment. This project intends to build a user-friendly desktop based entirely on free software. It is not a window manager in itself but co-opts with window managers. See fvwm2gnome for instance.
XwwChooser is an application designed to ease the switching of window managers in X windows.
