HP-Specter-x360-15-df0009nl brightness and auto screen rotation

[speleoalex]

Good morning,
I want to share this script I created for HP-Specter-x360-15-df0009nl.
Allows you to change the screen brightness and make it rotate automatically.

It must be executed when the window manager is started
I tested it with Kubuntu 19.4

HP-Spectre-x360-15-df0009nl.sh

#!/bin/bash
cd "$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

abs() { 
    [[ $[ $@ ] -lt 0 ]] && echo "$[ ($@) * -1 ]" || echo "$[ $@ ]"
}

statePrev="-":

while :

#-------------brightness
Current=$(cat /sys/class/backlight/intel_backlight/device/intel_backlight/brightness)
set=$(bc -l <<< "1 / (120000 / $Current)")
if [ $oldset = $set ]; then 
    echo ""
else
    xrandr --output eDP-1 --brightness $set
    oldset=$set

this version solves the problem that sometimes a different id is assigned to the touchscreen
