I've got a udev rule that is properly matching, but it is not executing the command in the RUN+="/usr/bin/synclient TouchpadOff=1" properly. If I change that to be some sort of test shell script then it works fine.

If I run synclient TouchpadOff=1 from the command line I get no return and it doesn't work. However, adding sudo to that line disables the touchpad as intended.

Is udev not executing this command with superuser permissions?

Ubuntu 15.04

synclient depends on X server to work. See man synclient. So you need to define the DISPLAY and XAUTHORITY environment variables of the current running server.

If you are using just a single user account with simple server setup, try this:

RUN+="/bin/sh -c 'DISPLAY=:0 XAUTHORITY=/home/<username>/.Xauthority synclient TouchpadOff=1'"

Change <username> to your username.
