Funny you should mention that.  I'm just completing a chapter on
window managers for the upcoming edition of "The Complete FreeBSD".
The last edition was based on fvwm2, but I decided this time to
recommend KDE instead.  The reasoning was that it's easier for a
newbie, and that it's relatively complete.

As you can see from http://www.lemis.com/grog/diary-jan2003.html, I've
changed my mind after actually using it.  I still describe KDE, but I
point out that you have a choice, and that for many people fvwm2 might
be a better choice.

As far as size goes, I see:

These are default installations in each case.  242 MB of process space
for kde, 14 MB for fvwm2.  No wonder KDE is slow.  The machine I'm
testing on has 128 MB of RAM, so it's swapping all the time.

These addons for fvwm2 take up a surprising amount of space.  I'm also
running fvwm2 on my main machine, on a multi-head display.  and there
I get:

  $ ps aux|grep fvwm
