Increase Scroll Speed Kensington Trackball

in flag
Matt

I have a Kensington Expert Mouse Trackball I am using on Ubuntu. It was a 'plug-and-play' set up so everything is working as expected. Although, I did notice the scroll speed using the scroll ring is a little slow for my liking.

I looked into the xinput command and that looks simple enough, but my question is: Which one of these commands do I need to adjust to increase the speed of the scroll ring?

$ xinput list-props 10

I have an alternative slotion to increase the scroll speed.

Step 1. Install the package lm wheel using the command

sudo apt-get install imwheel

Step 2. Download a bash script from here. Save the script in your home folder. Make it executable. Execute the script to open a window that helps to change your scroll speed.

+1 this works great. For anyone else wondering, changing the value in the window does *not* take effect immediately, you need to "Apply", play around, and try again if it's not to your liking. The default setting is "1" and even "3" is plenty fast for me.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
