udev rules behaves opposite when executing startx

["J. Bakshi" <j.bakshi@unlimitedmail.org>]

Hello list,

Here is my udev rules which disable touchpad when I plug my usb external mouse, and enable it again, when removing the mouse 

```````````````````
ACTION="add", SUBSYSTEM="input", ENV{ID_CLASS}="mouse", ENV{DISPLAY}=":0.0", ENV{XAUTHORITY}="/home/user1/.Xauthority"  RUN+="/usr/bin/synclient TouchpadOff=1", RUN+="/bin/su user1 -c 'DISPLAY=:0.0 notify-send %k ' "

ACTION="remove", SUBSYSTEM="input", ENV{ID_CLASS}="mouse"  RUN+="/usr/bin/synclient TouchpadOff=0", RUN+="/bin/su user1 -c 'DISPLAY=:0.0 notify-send %k ' "
``````````````````````````````

The rules is running well within X. But only when I start my WM with startx , then the rules behaves opposite. With no mouse attached , the touchpad is still inactive. Though by pluging/unpluging the mouse, the rules start working normally. I don't understand why startx makes the rules behave so. Could anyone give me any clue please ? 

Thanks
