Hierbij een door mij gebruikte oplossing om softwarematig kleur en helderheid te beïnvloeden.
Linker Ctrl + pijltje omlaag/omhoog = helderheid
Linker Ctrl + pijltje links/rechts = roder/groener
Voorbereiding:
Installeer xbindkeys, optioneel xbindkeys-config
Terminal:
sudo apt install xbindkeys xbindkeys-configCheck de naam van je Beeldscherm, in mijn config is dat DVI-I-1, kan bijv. ook HDMI-0 zijn of VGA-0
Je kunt toetsen toewijzen via xbindkeys-config of maak een bestand .xbindkeysrc , DVI-I-1 vervangen door jouw monitornaam, met de inhoud:
# For the benefit of emacs users: -*- shell-script -*-

# Version: 1.8.6

# If you edit this file, do not forget to uncomment any lines
# that you change.
# The pound(#) symbol may be used anywhere for comments.
#
# To specify a key, you can use 'xbindkeys --key' or
# 'xbindkeys --multikey' and put one of the two lines in this file.
#
# The format of a command line is:
# "command to start"
# associated key
#
#
# A list of keys is in /usr/include/X11/keysym.h and in
# /usr/include/X11/keysymdef.h
# The XK_ is not needed.
#
# List of modifier:
# Release, Control, Shift, Mod1 (Alt), Mod2 (NumLock),
# Mod3 (CapsLock), Mod4, Mod5 (Scroll).
#
# The release modifier is not a standard X modifier, but you can
# use it if you want to catch release events instead of press events
# By defaults, xbindkeys does not pay attention with the modifiers
# NumLock, CapsLock and ScrollLock.
# Uncomment the lines above if you want to pay attention to them.
#keystate_numlock = enable
#keystate_capslock = enable
#keystate_scrolllock= enable
# Examples of commands:
"xbindkeys_show"
control+shift + q
# set directly keycode (here control + f with my keyboard)
#"xterm"
# c:41 + m:0x4
# specify a mouse button
#"xterm"
# control + b:2
#"xterm -geom 50x20+20+20"
# Shift+Mod2+alt + s
#
## set directly keycode (here control+alt+mod2 + f with my keyboard)
#"xterm"
# alt + c:0x29 + m:4 + mod2
#
## Control+Shift+a release event starts rxvt
#"rxvt"
# release+control+shift + a
#
## Control + mouse button 2 release event starts rxvt
#"rxvt"
# Control + b:2 + Release

.xbindkeysrc is een verborgen file, zichtbaar te maken in bestandsbeheer met Ctrl+H
Dan het "uitvoerende" script, maak een bestand brightness.sh met de inhoud:
#!/usr/bin/env bash
set -e
get_display_info() {
xrandr --verbose | grep -m 1 -w "$1 connected" -A8 | grep "$2" | cut -f2- -d: | tr -d ' '

Herstart de machine, nu zou je met Linker Ctrl + pijltjestoetsen e.e.a. moeten kunnen aanpassen.
En nee is niet van mij, maar bijeengesprokkeld op het net.
