Now is time to talk about Linux desktop and its features, especially about GNOME Desktop Environment and Window Maker integration. I hope you tried how comfortably they are, sometimes i switch between them going to the most "spartan" Window Maker, at all my favorite.
This is a quick and dirt trick, to keep the settings of GNOME Desktop while using the Window Maker Window Manager, like fonts, styles, themes of your favorites GTK apps.
Go to your home directory, something like
/home/(your ID) ... mine is
/home/andrea. Settings about Window Maker are stored into the directory GNUstep. There's a little script that Window Maker calls when it start, is stored in
/(your homedir)/GNUstep/Library/WindowMaker and is called autostart.
"It's important to create the autostart file if not present and mark it at executable (chmod +x) then we will be able to add what we want to be launched at Window Maker startup."
/(your homedir)/GNUstep/Library/WindowMaker/autostart. First line will be this:
/usr/lib/gnome-settings-daemon/gnome-settings-daemon &, (ampersand keep your process in background). May happen that your Linux Distribution differs, but as you note is always gnome-settings-daemon that keep your settings cool.
