[openbox] xset from hot key

[Jorge Almeida]

I'm trying to put the LCD monitor to sleep via rc.conf:


    <keybind key="0xdf">
      <action name="Execute">
        <execute>xset dpms force off</execute>
      </action>
    </keybind>

The problem is that upon pressing the key the monitor darkens but then
it wakes again one or two seconds later. The monitor button doesn't
change from green to orange.
I also tried putting sh -c "xset dpms force off", same problem. It
happens as if some key were pressed after the hotkey...

The key is one of those non-standard ones (it says "user", and I
suppose it is some Windows stuff)  But I tried with "C-E" and it has
exactly the same behaviour.
When run from a shell, the command "xset dpms force off" works as
expected (dark screen, orange button, wakes when some key is pressed).

$ xset -q
