  Ok, this is weird. I tried setting WINDOW_MANAGER both through my
.xsession, and through /etc/environment. Both appear to set it
correctly; if I then do 'echo $WINDOW_MANAGER' in a terminal, I get
/usr/bin/compiz as I had set it. In addition, if I execute gnome-wm by
hand from the terminal, it does start compiz as it should. However,
the gnome-wm that's executed by gnome-session does not; it starts
metacity. Does gnome-session perform environment variable scrubbing
perhaps? Is there a way to check the environment of a running process?

  Would these be the .desktop files in /usr/share/app-install/desktop/
or in /usr/share/app-install/desktop/? In any case, in both locations
compiz.desktop has, among others, the following lines that seem
relevant:

# name of loadable control center module
X-GNOME-WMSettingsModule=metacity
# autostart phase
X-GNOME-Autostart-Phase=WindowManager
X-GNOME-Provides=windowmanager
# name we put on the WM spec check window
X-GNOME-WMName=compiz
# back compat only
X-GnomeWMSettingsLibrary=compiz

  I don't know, as long as there's a way to configure the window
manager that GNOME uses, I'm happy. Ideally it would be a nice GUI
dialog, but I'll take what I can get. The problem is that I can't seem
to be able to make any of this work just now. :^) Any further hints
would be appreciated.
