Lightweight X environment

Some people tend to use just KDE or GNOME Environments that come with a lot of applications
that most of the times you don't use or there is a replacement for it, better, in the CLI(Command Line Interface), that's essencial, so here is a list of some Window Managers for the X Window System that i have tested and some interesting ones that some day i might give a try.Note, here is a list of Window Managers, you still can use your GNOME or KDE applications, for GNOME you will need to look for GTK libraries and KDE qt ones.

• IceWM
• Fluxbox
  
• Blackbox
  
• OpenBox
• Hackedbox
• Matchbox

I can give you a hint, install first the x server, and use it to find out the dependencies,
if you specify to install something like xorg, maybe it will grab the whole
xorg modules with you.

After you finish it, try to get the list of what are those installed packages, some times is better have 2 partitions, one for you work into untill you get what you want and other for the "backup" purpose, that's good if you don't have some practices with CLI, what might happen is your qt or gtk application wont run and when those GUI applications are critical for you because you manage the system from them, then this will be a great challenge for you, just don't forget, if you
physically hurt your computer it wont fix what you want, ;).

Remember all days i have something to fix too, sometimes is better we use our time with something more relevant.
