So, SESSION_MANAGER is defined running the command in the gnome user environment, but it's not defined in the root environment neither in the minimal environment of the fake sds command: sudo -u <gnome username> gnome-session-save --gui --kill The only possibility I see to solve this problems is: to hack the gnome initialization procedure to do something as: echo $SESSION_MANAGER > /tmp/gnome-session-manager (e.g. executing it as an auto startup program) Then in the power-button activation script to do: sudo -u <gnome-user> kill-gnome-session where kill-gnome-session is something as #! /bin/sh $SESSION_MANAGER=$(cat /tmp/gnome-session-manager) gnome-session-manager --gui --kill It seems to me too complex (and not portable, you need to modify manually the gnome-session-properties, and you need *root* permission to write in /tmp). So this doesn't seem at all a viable solution. Could someone point out a simpler/better solution? KDE solves the problem in this way (for what I can see from my /etc/acpi/power-button script): if ps -e -o command | grep -q '[k]desktop' && test -f /usr/bin/dcop; then dcop --all-sessions --all-users ksmserver ksmserver logout 0 2 0 && exit 0 else ... Is possible to use a similiar method (maybe using DBUS) with gnome?
