gnome-screensaver on a smartphone

[x muc ccc de]

hi!

i'm trying to set up gnome-screensaver for a smartphone.
to achieve the well-known behaviour of dimming halfway some time 
before blanking, an extra stage before blanking is necessary.

when i played around with dbus a bit, i discovered that there is 
already such a thing: member=SessionPowerManagementIdleChanged.

sadly, after SessionPowerManagementIdleChanged true was sent but 
while the screensaver is still inactive, neither activity nor 
gnome-screensaver-command -a or -d trigger any dbus message. i guess 
SessionPowerManagementIdleChanged false would be most straight 
forward (though a SessionIdleChanged false or an ActiveChanged false 
would do the job, too).
this means that undimming on activity before the blank event occured 
can't work.

i guess this is a bug - or did i miss something?

and while i'm at it:
- i didn't find the gconf path to configure the 
'SessionPowerManagementIdleChanged' timeout - where is it?
- minute-granularity for the timeouts is kind of too coarse on a 
smartphone - esp. for the dimming and blanking events - isn't it? 
couldn't that be changed to seconds instead?

kind regards,

	Chris
