Oki,
so I installed metacity

[root at localhost salsa]# urpmi metacity
Pour satisfaire les dépendances, les paquetages suivants vont être 
installés (6 Mo):
libmetacity-private0-2.6.5-3mdk.i586
metacity-2.6.5-3mdk.i586
Est-ce correct ? (O/n) o

ftp://ftp.ens-cachan.fr/mirror/Mandrakelinux/devel/10.0/i586/Mandrake/RPMS/metacity-2.6.5-3mdk.i586.rpm

/var/cache/urpmi/rpms/metacity-2.6.5-3mdk                       .i586.rpm

But now how can I change my WM (xfwm4)  ?
I think I have to edit the file "xinitrc".
But I couln't find this file neither in the directory /etc nor in the 
directory /usr/local/etc. I installed xfce with urpmi. I use also KDE.


What do I do ? I have to create a file xinitrc ?
