Ah, yes. For icewm and fluxbox, the global configs are in /usr/share I think. I haven't tried adjusting wmaker or xfce yet. I figure that a few barebones minimal window managers are a good thing.

When you are in those WM's as knoppix in your chrooted environment, you are adjusting the user-level configs in /home/knoppix that eventually get put in /etc/skel. However these WM's are set to use the global configs instead of the uyser configs. So to make changes to them, I suggest comparing your already modified configs with the ones in /usr/share/icewm and /usr/share/fluxbox.

Icepref, myice, and several other gui configurators are available for icewm if you don't want to edit the configuration by hand. You'll just need to install one of them with apt-get (and possibly remove it later if you are running low on space). I usually edit fluxbox configs by hand.

Also, if you want to set bmp/jpg/png backgrounds in fluxbox instead of the tiles that its themes use, you can edit the theme files. To accomplish this I install eterm (a transperancy-capable terminal) which includes the program esetroot. Esetroot can be used in the fluxbox theme configurations to set an image as a background. This is not the only way to set a background in a fluxbox theme, but its the way I like to do it.

I didn't know anything about tweaking icewm or fluxbox until I started remastering my own Knoppix. Google and various Linux forums were able to answer all my questions though.

I also had some trouble with getting Gnome to restore its saved session, but I can't remember now what I did to make it work......
