i needed something like volumouse because using the scroll just over the volume button is annoying
https://github.com/pzim-devdata/Tools-for-Linux/tree/master/Volumouse
here it is, you just have to edit the resolution to fit your monitor, it's in the first lines, make executable and bam, it just works.

here is the code for the lazy, you run it in the console so you know if you need some libs (i did) and then you can scroll mouse in the upper right corner to change volume.

the code is for 2560x1440, change it with your screen, i'm using only right because i need to disable the corner left kde action and i'm lazy.

Code: Select all

#!/usr/bin/env python
#-*-coding:utf-8-*-
# python3-xlib package must be installed to run this script :
#sudo apt-get install python3-xlib
#or sudo apt-get install python-xlib

import os
from Xlib import X, display
from Xlib.ext import record
from Xlib.protocol import rq

Screen_resolution = (2560,1440) # type here your screen resolution

Corner_area = 20 # Type here the size of the virtual squares that receive wheel up and down event at the corner of your screen

# Let's set up the commands
def volume_up():
    os.system("amixer set Master 5%+ & pid=$!")

    #os.system("amixer -q sset Master 5%+ & pid=$!")
    #os.system("pactl set-sink-volume 0 +5% & pid=$!") 
    #os.system("pactl set-sink-volume 2 +5% & pid=$!")
    #os.system("pactl set-sink-volume 1 +5% & pid=$!")
   
    # write your bash command between "" to volume up
   
    # use "& pid=$!" end of your command to prevent freezing python script if your command takes long time to process.

def volume_down():

    os.system("amixer set Master 5%- & pid=$!") 
    #os.system("amixer -q sset Master 5%- & pid=$!")
    #os.system("pactl set-sink-volume 0 -5% & pid=$!")
    #os.system("pactl set-sink-volume 2 -5% & pid=$!")
    #os.system("pactl set-sink-volume 1 -5% & pid=$!")
