With the currently used input driver system it is not possible to change the scroll speed of your mouse, at least not without drawbacks. You are able to adjust the scroll speed for Qt-Applications using a KDE Settings but the only current way to change the scrolling in a generic fashion is by using
imwheel which seems to be problematic in many ways (see comments). In the future this will be fixed with
libinput and the systemd hardware database.
imwheel with the following command or from the Software Center:
$ sudo apt-get install imwheel
And edit the configfile
~/.imwheelrc with an editor of your choice (e.g.
gedit). Fill in the following for increasing the scroll speed for every Command:
None, Up, Up, 3
None, Down, Down, 3
3 is the increase of the scroll. For more specific scroll increases take a look to the manpage
$ man imwheel
or read the README of the project.
You can start it by typing:
be sure that you don't start the imwheel twice! That's a known bug, but you can stop imwheel with the command:
$ killall imwheel
This tutorial is currently under development. Hints and corrections are welcome, at this time I have not been able to actualy change behavior using this tutorial. So it is work in progress.
libinput seems to be included with Wily Werewolf (15.10) where you need to install the package
xserver-xorg-input-libinput. After you installed
$ sudo apt-get install xserver-xorg-input-libinput
it should be used for every input after you restarted the Xorg (logout would be sufficient). Now that you are using
libinput you are able to adjust the settings of your mouse. You can find a full tutorial in the file /lib/udev/hwdb.d/70-mouse.hwdb. Let me cover here only the basics.
The following steps are need to be done as
root. Because of that I am friendliy reminding you that everything you do you need to take responibility.
First get the vendor id
<vid> and the product id
lsusb. Here with a MX 518 Logitec Mouse as example. If you have the following line in the output of
Bus 005 Device 002: ID 046d:c051 Logitech, Inc. G3 (MX518) Optical Mouse
046d and the
Then create a File that looks like the following with
gksudo gedit /etc/udev/hwdb.d/71-mouse.hwdb
For example this file:
So in this file the mouse wheels click angle is set to 30°. To use this setting you need to update the hwdb with the following commands:
udevadm hwdb --update
udevadm trigger /dev/input/event*
