I have disabled GDM and start GNOME with gnome-session from .xinitrc . Now when i press Sleep button, GNOME says it cannot suspend. The same is with pressing suspend or hibernate buttons on Shutdown window.
At the same time "sudo pm-suspend" and "sudo pm-hibernate" DO work. So, i would like to disable GNOME from listening to ACPI events and to configure everything via acpid scripts.
I tried to stop acpid to see if GNOME will not receive events in this case, but it still does.
So, the question: how can i stop GNOME from listening to ACPI events?

I found that i can do this by killing gnome-power-manager... but this way i lose battery monitor on the panel...
