Ubuntu 20.04 mouse scroll wheel speed

I had a very slow scroll speed until I found that.

Install and run

You have to install imwhell with :
```
sudo apt install imwheel
```


2. And download this bash script on [http://www.nicknorton.net](http://www.nicknorton.net/mousewheel.sh) (thanks to him)
You can type, as @victoor say in comments :
>You can just do ` bash <(curl -s http://www.nicknorton.net/mousewheel.sh) ` instead of copy the script manually and changing permissions. :) 
    ```


#!/bin/bash
# Version 0.1 Tuesday, 07 May 2013
# Comments and complaints http://www.nicknorton.net
# 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
".*"
None,      Up,   Button4, 1
None,      Down, Button5, 1
Control_L, Up,   Control_L|Button4
Control_L, Down, Control_L|Button5
Shift_L,   Up,   Shift_L|Button4
Shift_L,   Down, Shift_L|Button5
EOF
fi
##########################################################
CURRENT_VALUE=$(awk -F 'Button4,' '{print $2}' ~/.imwheelrc)
NEW_VALUE=$(zenity --scale --window-icon=info --ok-label=Apply --title="Wheelies" --text "Mouse wheel speed:" --min-value=1 --max-value=100 --value="$CURRENT_VALUE" --step 1)
if [ "$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

Then set up the .sh file to executable with : ```

chmod +x mousewheel.sh

4. And then run script with :
    ```


./mousewheel.sh

And set your mouse wheel speed in the popup by clicking on apply button. (my setting is 7) Re-run script for change.
Finally add imwheel in ubuntu startup application.

If you have troubleshooting with previous and next mouse buttons :

Add -b "4 5" to imwhell :



imwheel -b "4 5"
