Hi guys,

I use de xf86-video-fbdev (framebuffer) driver in the X Window, but DPMS 
is not working, although it is enabled:

[sebas at parabolaSebas64 ~]$ xset -q
Keyboard Control:
   auto repeat:  on    key click percent:  0    LED mask:  00000002
   XKB indicators:

DPMS (Energy Star):
   Standby: 600    Suspend: 600    Off: 600
   DPMS is Enabled
   Monitor is On

I even try

xset dpms force suspend/standby/off

with no luck. The screen goes black but the monitor doesn't go to 
powersave mode.
I use this monitor in the past (so I'm sure the monitor does indeed go 
in powersave mode).

Well any suggestiond are very welcome.

Thanks in advance.
