Systemd-user-service to enable keyboard gives no error but doesn't work

I have a bad laptop keyboard and a much better Lily58, so I wrote a bash-script to be able to disable my laptop keyboard so I can place the Lily58 on it and re-enable it after. But when I disable the laptop keyboard, it stays disabled if I put the laptop in suspension while I would prefer it to be automatically re-enabled on resume. So I wrote a short bash script

#!/bin/bash

fconfig="/home/alex/.keyboard" 
id=$(xinput | grep AT | sed -n '2,2p' | awk '{print $7}' | sed 's/[^0-9]*//g')

if [ -f $fconfig ]; then
  read -r var $fconfig
  fi
fi

This checks whether "disabled" is in the file /home/alex/.keyboard that tracks whether the keyboard is enabled, and if so runs xinput to re-enable using the id it got by sifting through the output of xinput in the manner used in the definition of id, then set /home/alex/.keyboard to enabled. This works as it should when I trigger the bash-script from the terminal, but when I start the systemd-service

[Unit]
Description=This service enables your keyboard after suspension
PartOf=graphical-session.target

[Service]
Type=oneshot
ExecStart=/home/alex/bash/enable-keyboard

[Install]
WantedBy=multi-user.target

that I want to run after suspend, it sets /home/alex/.keyboard to enabled but does not actually re-enable my keyboard. Moreover, journalctl -xeu enable-keyboard.service indicates no error:

What is going wrong? Edit: If I put a clause into the script to print the output of xinput into a file, the output consists of one empty line. Edit: the output of systemctl --user status dbus.socket dbus.service is
