On Linux, I use xinput set-prop to enable tapping the touchpad to click. To find the relevant device id as well as property number, I use xinput list-props.
Unfortunately, I find that both the device id and property number are not consistent across sessions. After a reboot, I often need to reconfigure these manually.
I am wondering what the cause of this is, and how to deal with the issue in such a way that manual reconfiguration is not needed after every reboot.
The way to handle this is to write your own xorg.conf file (or put a file in the subdirectory where xorg.conf parts are collected, if your distribution does it that way), and use the InputClass section to match your device using vendor and device id or other hardware identifiers, and then apply the InputDevice options that are also valid for the InputClass section to enable tapping on the touchpad, or whatever else you want to configure.
Careful, the option names can be slightly different from the xinput names, so look closely. Inspect /var/log/Xorg.0.log after (re-)starting the X server to see if it worked.
See man xorg.conf for options, or google for tutorials (there should be quite a few).
