Bon ben c'est pas gagné parce que ma MDK 8.2 (je sens que la Debian m'appelle...) a l'air d'utiliser des fichiers de conf en cascade.
Bon je vais voir la fin de /etc/inittab
# Run xdm in runlevel 5
# xdm is now a separate service
x:5:respawn
etc/X11/prefdm -nodaemon
Bon je vais donc voir ce prefdm
# we have to assume that /etc/sysconfig/desktop has two variables, DESKTOP
# and DISPLAYMANAGER because administors may prefer a specific DM regardless
# of desktops.
# DISPLAYMANAGER is referenced by this script, and DESKTOP is referenced
# as system-wide default by /etc/X11/Xsession script only when X-session
# is opened by "startx" command.
# when DMs open an X-session, they send DESKTOP, which is in this case
# directly selected by users, as a commandline argument of /etc/X11/Xsession.
# actually Xsession script is only able to know by existance of its first
# argument whether it is called by DM or "startx". see the logic
# in /etc/X11/Xsession.
# If DISPLAYMANAGER is not defined, then assume that it is the same as DESKTOP

Ce que j'ai pu en comprendre avec mes connaissances très médiocres en bash c'est que /etc/sysconfig/desktop gère le desktop manager. Or si on le regarde :
DISPLAYMANAGER=kdm
Là je dois avouer que je comprends rien
