How do I adjust the pointer speed and scrolling speed of a trackpad?
This is the only way I can think of that might change pointer speed beyond the default allotment. It might not work.
Install dconf
editor:
sudo apt-get install dconf-tools
Run dconf-editor
and navigate to:
org -> gnome -> settings-daemon -> peripherals -> touchpad
There you can play around with the value of motion-acceleration
. The max value that System Settings gives is 10, so maybe setting it to 20 would work.
