For the newly created user a default Gnome session consists of the
following processes

/usr/sbin/gdm3
 \_ /usr/lib/gdm3/gdm-simple-slave
--display-id /org/gnome/DisplayManager/Display1
     \_ /usr/bin/Xorg :0 -br -verbose -novtswitch
-auth /var/run/gdm3/auth-for-Debian-gdm-mYMD6w/database -nolisten tcp
vt7
     \_ /usr/lib/gdm3/gdm-session-worker
         \_ gnome-session
             \_ /usr/bin/ssh-agent /usr/bin/dbus-launch
--exit-with-session gnome-session
             \_ /usr/lib/gnome-settings-daemon/gnome-settings-daemon
             \_ gnome-power-manager
             \_ /usr/bin/gnome-shell
             |   \_ gnome-terminal
             |       \_ gnome-pty-helper
             |       \_ bash
             |           \_ ps axwfu
             \_ update-notifier
             \_ /usr/lib/evolution/3.0/evolution-alarm-notify
             \_ /usr/lib/gnome-disk-utility/gdu-notification-daemon
             \_ kerneloops-applet
             \_ gnome-screensaver
             \_ nm-applet
             \_ python /usr/bin/system-config-printer-applet

Before I used to see a /usr/bin/metacity in the tree below
gnome-session.

Exactly.

Yes, it is. I use to run compiz.

Yes, that's the way it seems to me, because of the segfaults logged
to /var/log/messages whenever I try to log into a default GNOME session.

'Unfortunately' not.
