this is the output of all input devices. the laptop doesn't seem to recognize the touch pad at all.

If anyone can help would really appreciate it.

Hi,

Welcome to LQ!

Do you have a hot key set to enable the touch pad?

I use this script to enable/disable the pad,touchpad.sh ;

Code:

cat touchpad.sh
#!/bin/bash

# touchpad.sh Written by Atanas S / Siteground Support Team

# First we need to get the device ID from the xinput
# if it does not work for you, you may need to set the cut -f option to another number
# I would suggest that you test the command in your terminal first to see the result
# It should output an integer usually between 8-15, at least on my lap top :D

getdev=`xinput list |grep pointer |grep PS |cut -f 2`
devid=${getdev/id=/}

#Second we need to get the device status, if it is enabled or not

# if it does not work for you, you may need to set the cut -f option to another number
# I would suggest that you test the command in your terminal first to see the result
# It should output 0 or 1

getstatus=`xinput list-props $devid |grep 'Device Enabled' |cut -f 3`

#once we get the device status depending on the status we set it the other way arround
        if [ "$getstatus" == "1" ]; then
        newstatus="0"
        else
        newstatus="1"
        fi
`xinput set-prop $devid "Device Enabled" $newstatus`

I launch this from a vt console while in my DE. Be sure to set the script as execute for user(s).
The script will toggle the state of the touch pad.
Hope this helps.
Have fun & enjoy Gnu/Linux!

Anything in /sys/bus/i2c/devices?

I got a new laptop recently and a SYNA3602 device could be seen in /sys, but nothing in /proc (nor /dev, nor anything in X). Under distros other than Slackware the touchpad worked, and tracked it down to the kernel missing Intel Cannon Lake pin control support.

I've heard of PopOS, but not familiar. Do try some other distros, live environments are fine, to see if Linux can work with the trackpad. Then try and figure out what differs.

Good luck
