I use kubuntu 18.04 and the biggest number of lines you can scroll by mouse wheel is 12. With big monitor resolutions and long folder lists (not my doing) I would like to increase the number of lines to e.g. 20 to reduce my finger scrolling.
How can I do that in a way, that it stays permanently after reboot?
I have read, that imwheel should not be used anymore with 18.04.
