false udev event

false udev event

[J. Bakshi]

Hello list,

I have a strange problem of triggering false udev event !!

Here is my rule sets to active/in-active touchpad based on the presence of usb mouse

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

ACTION="remove", SUBSYSTEM="input", ENV{ID_CLASS}="mouse"  RUN+="/usr/bin/synclient TouchpadOff=0", RUN+="/bin/su joy -c 'DISPLAY=:0.0 notify-send %k ; syndaemon -t -k -i 3 -d' "
````````````````````````````

But when I start my machine, the rules  actually behaves opposite. i.e. it disable touchpad and with *no mouse attached* !!!  I face the same when the PC alive from hibernation. How to fix this false event ? 

Thanks

This rule is fundamentally broken.  You are explicitly setting the 
environment to point to your .Xauthority file and the first instance of 
an X server, which of course, assumes that you are logged into that X 
instance at the time.  When this rule is processed, that is almost 
certainly not going to be true.

It also will run repeatedly for every input device in the system.  Maybe 
you meant ENV{ID_CLASS}="mouse" instead of ENV{ID_CLASS}="mouse"?

This is not a job for udev at all.  You might try using your .xinitrc or 
something.
