Well, now that it's votin' time... I use CWM on my OpenBSD machines and FVWM on my other machines. I don't like giving terse responses, so... CWM is a very lightweight window manager that started out as a port of EvilWM but ended up being entirely rewritten. There are no window decorations, and very nearly everything can be controlled by the keyboard. There are builtin functions for completing programs, "commands" (which are like program shortcuts you setup), and SSH host entries (gotten from your known_hosts file). You can put windows into "groups" and then show only a single group at a time, effectively creating virtual desktops. If a window is not in a group, it is always shown, like being "sticky" in virtual desktop parlance. However, unlike virtual desktops you can show multiple groups at the same time. Additionally, you can select windows by searching for their title, which is cool if you've got just a ton of windows all together in the same group. The code seems very stable to me personally at this point (I've never had a crash yet after a few months of using it). While it's developed in the OpenBSD project, the code can be slightly modified to run on Linux as well.

The ones i use in order of appearance. ratpoison,xmonad,dwm, and rarely pekwm. pekwm is the most decent non tiling wm there is today IMO.

Compiz, if used with moderation. No youtube fireworks for me.

Window Maker is old, with little active development for some years, but those 64x64 pixel icons are just so damn easy to hit using the touchpad on my laptop when the train is rattling along!

I voted for openbox because my only problem with it is that, now that I've found it, I'll no longer have the fun of looking for a window manager that suits me perfectly.

Fluxcapa... i mean fluxbox!

Fluxbox...

Fluxbox (and icewm on antiX!)

Compiz

Fluxbox

TWM is the window manager I use most now. Fluxbox is ok, and what I use the second most, and I still think FVWM is the most powerful window manager available -- I just don't need that power right now so I'm not using it currently.

Compiz...

voted compiz and it is default on my system. going to try some of the others.

Am I blind or there isn't XMonad? It just happens to be the finest WM I've seen so far. That is a real missing here.

However, now using ratpoison and gone for it!

Why no LXDE? Maybe it will win WM - 2009...Fluxbox...I used to like Window Maker but I guess they stopped working on it. I wish somebody else would take it up.
