If you have installed kubuntu, you won’t find a setting to change the speed of the mouse wheel. So you have to install it.
I found this cool tutorial that helped me with that : tutorial
- First we have to install these two apps :
sudo apt install imwheel zenity
- Then we have to create a new file containing the script to run a window to change the speed setting of the mouse wheel : (you may choose a good location for this file, for example /home/tools)
sudo nano mousewheel.sh
- Insert this code in it :
#!/bin/bash
# Version 0.1 Tuesday, 07 May 2013

# GUI for mouse wheel speed using imwheel in Gnome
# imwheel needs to be installed for this script to work
# sudo apt-get install imwheel
# Pretty much hard wired to only use a mouse with
# left, right and wheel in the middle.
# If you have a mouse with complications or special needs,
# use the command xev to find what your wheel does.
#
### see if imwheel config exists, if not create it ###
if [ ! -f ~/.imwheelrc ]
then
cat >~/.imwheelrc<<EOF

if [ "$NEW_VALUE" == "" ];
then exit 0
fi
sed -i "s/\($TARGET_KEY *Button4, *\).*/\1$NEW_VALUE/" ~/.imwheelrc # find the string Button4, and write new value.
sed -i "s/\($TARGET_KEY *Button5, *\).*/\1$NEW_VALUE/" ~/.imwheelrc # find the string Button5, and write new value.
cat ~/.imwheelrc
imwheel -kill
- Or you can grab it directly using :
curl -s http://www.nicknorton.net/mousewheel.sh > mousewheel.sh
- Make it executable :
chmod +x mousewheel.sh
- Run it :
./mousewheel.sh
- I have set it to 2 since higher values made the scrolling too fast.
