Well ... if all else fails:
just create a ~/.xinitrc (or ~/.xsession depending on
how you start X [via session-manager or startx]) and
start the things you want to run within the gnome-session
before you start gnome...
E.g. (I use xdm, so here's my .xsession)
Code:
/usr/local/bin/tpb&
xscreensaver&
exec /usr/local/bin/fluxbox
You'd obviously want to replace the
exec fluxbox
line with whatever starts Gnome.
Cheers,
