How to change my mouse wheel scroll rate?

Solution 1:

The fix for me for this (I had it for months) was pretty surreal and like most folks I didn't believe it until I did it:

Some MS mice have a scrollwheel bug.

Try unplugging the USB cable / dongle then plug back in.

Also, I noticed that if you have the dongle plugged in to the computer and the mouse has an on-off mechanism then you can just turn the mouse off and back on. That resets the data link between the mouse and dongle.

:)

Solution 2:

I wanted to do this too, and I figure I most often want to do it in a web browser (where else do you really mouse-wheel scroll a great deal?)

For Google Chrome

One can no longer change the scroll amount with command line parameters. However, you can use this add-on extension: https://chrome.google.com/webstore/detail/chromium-wheel-smooth-scr/khpcanbeojalbkpgpmjpdkjnkfcgfkhb?utm_source=plus

For Firefox

1. In the url field, type about:config.

2. Search for the following settings and change their values as desired:

   mousewheel.system_scroll_override_on_root_content.enabled
   mousewheel.system_scroll_override_on_root_content.horizontal.factor
   mousewheel.system_scroll_override_on_root_content.vertical.factor
   

Solution 3:

From triaged bug #619403 on mouse-wheel acceleration against xorg-server with a link to this patch you can see there is work in progress.

In addition there is a Wiki on how to configure input devices that gives you ideas on what is possible at present:

Use xinput to show setting of your input devices:

xinput --list gives you information on your hardware xinput query-state "name of device" lists the current settings (including mouse wheel!)

Only after you know how your mouse is set up you are able to change these setting using xinput with the option appropriate for your device.

Solution 4:

The option to configure mouse wheel speed in chrome seems to have been removed, however the Chromium Wheel Smooth Scroller extension seems to work really well.
