  Hi everyone, recently, I come up writing a udev rules to disable the touchpad while I use the mouse. But I came across a strange situation as the title. I have tried the "synclient", but it doesn't seem to work at times.

  synclient TouchpadOff=1

  I lean how to do that from the web-site below. I have read it
  completely at least twice.

  I want to analyze how the udev works, so I the command below to grasp
  the information, you can check them out from the attachments.

  sudo udevd --debug

  You can see the corresponding message that present the situation at
  LINE 100 from add.txt. Like this.

  1325675158.824063 [4626] util_run_program: '/usr/bin/xinput' (stderr)
  'Unable to connect to X server'

  And here is my udev rules.

  ACTION=="add", SUBSYSTEM=="input", ATTR{name}==" USB OPTICAL MOUSE", RUN+="/usr/bin/xinput set-prop 13 125 0"
  ACTION=="remove", SUBSYSTEM=="input", ATTR{name}==" USB OPTICAL MOUSE", RUN+="/usr/bin/xinput set-prop 13 125 1"
