fvwm, xfvwm: are they related? Also: how to get transparency with cairo-clock
 

I'm running fvwm on my laptop and I just finished installing cairo-clock. When I run cairo-clock, it runs as expected, but has a black box around it which is supposed to actually be transparent. I found this on the FAQ at http://macslow.thepimp.net/?page_id=23#mark_3:

Q: The clock compiles/installs, but when I run it there is such a terrible black square behind it?
A: Be sure to fire up your compositing-manager and the black square will magically vanish.

I've looked around to find out if I can fire up a compositing-manager with my setup and haven't found much out about it. Here: http://en.wikipedia.org/wiki/Compositing_window_manager
it explains that xfvwm is a combination of a window manager and a compositing manager.

Is xfvwm like fvwm? How could I get a compositing manager running without installing a new window manager as well? Any other suggestions? Thanks.

EDIT

Okay maybe I'm blind. In the first link that I posted there's a reference right at the beginning to compositing-manager xcompmgr. I'll see where that takes things.

xfwm is part of xfce, i think you have a mis-spelling...

Okay yeah, it does say xfwm. That would explain why my investigations into xfvwm were all dead ends. It's probably arisen from some form of orthographical compositing managers :) in my brain.

fvwm is a complely different window manager, so you probably got that from someone elses typo or something like that...
