bluetooth-keyboard not working after standby

[Ralf Dreibrodt]

Hello,

I have two X-server (with one xorg.conf) and one has a bluetooth-keyboard.

Everything is working, but after 20 minutes the keyboard enters a 
standby-mode and after that it is not working anymore, in X.

It is still working in the console (after pressing Ctrl+Alt+F1 on the 
USB-keyboard).

When I restart X, it is working again.

I have the same problem with my usb mouse. When I unplug it and plug it 
again, it is not working, until I restart X.

How can I solve the problem?

The parts from my xorg.conf:

Section "ServerLayout"
         Identifier      "seat1"
         Screen          "seat1" 0                               0
         InputDevice     "mouse1"        "CorePointer"
         InputDevice     "keyboard1"     "CoreKeyboard"
         Option          "AutoAddDevices" "False"
         Option          "AllowEmptyInput" "False"
EndSection
Section "InputDevice"
         Identifier      "keyboard1"
         Driver          "evdev"
         Option          "Device"                "/dev/input/event6"
         Option          "XkbLayout"             "de"
EndSection

(When I remove the AutoAddDevices and AllowEmptyInput then the "up" 
(arrow) key is not working anymore. It is always making screenshots.)
