[gpm] Suspend/Hibernate not working

["Bontemps Camille" <camille bontemps gmail com>]

Hi,I use debian etch

gnome-power-manager is 2.14.3-3+b1
dbus is  1.0.2-1
hal is 0.5.8.1-4

kernel is  2.6.18-3-686 (Debian 2.6.18-8)

I use the package of debian etch for install

My user is in the powerdev group.

running the following command respectively suspend and hibernate well
dbus-send --system --print-reply --dest=org.freedesktop.Hal /org/freedesktop/Hal/devices/computer org.freedesktop.Hal.Device.SystemPowerManagement.Suspend
 int32:0

dbus-send --system --print-reply --dest=org.freedesktop.Hal /org/freedesktop/Hal/devices/computer org.freedesktop.Hal.Device.SystemPowerManagement.Hibernate

when I try to suspend from the suspend button of my laptop or by choosing suspend or hibernate from the menu of gnome-power-manager, gnome-screensaver comes up but the laptop never suspend/hibernate and my keyboard is lock ( I can't type my password in gnome-screensaver). I can only reboot by using the sysRqKey or by pressing the powerbutton, Init tell me that some process hang.

I don't see any error message by running gnome-power-manager --no-daemon --verbose and don't know how to provide more information.

regards.
