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 ?

Solved :-)  the hitch is some where else. For those facing the same; actually touchpad driver is loaded twice. 

``````````````````
(**) SynPS/2 Synaptics TouchPad: Applying InputClass "evdev touchpad catchall"
(**) SynPS/2 Synaptics TouchPad: Applying InputClass "touchpad catchall"
``````````````````````

Adding  [  MatchDevicePath "/dev/input/event*" ]  at /usr/share/X11/xorg.conf.d/50-synaptics.conf has solved this. This option ensures the driver loading only once.

Thanks
