Activate additional buttons on your Mouse in Ubuntu

logitech ubuntu Activate additional buttons on your Mouse in UbuntuI bought a new Logitech M100 (which is a 7 button mouse) mouse a couple of days ago and after I plugged in the mouse I found out that ubuntu by default only uses five of the basic buttons i.e. main button (left and right) count as one, the downward click on the wheel counts as another, and the up/down scrolling also count as one each (2+1+2=5).

So 2 of my buttons (Tilt wheel Right/Left) were not working. So I went to google and found a really complicated method to do the thing , and it was a bit out dated too. So I went on experimenting with the devices and finally was able to come up with a vary easy process  to activate the additional buttons on the mouse. Follow the steps:-

STEP 1:First we need to find out the name of your mouse and its handler. For that issue this command in shell

egrep “Name|Handlers” /proc/bus/input/devices

Now you would be able to see something like this:

N: Name="Power Button"
H: Handlers=kbd event0
N: Name="Power Button"
H: Handlers=kbd event1
N: Name="AT Translated Set 2 keyboard"
H: Handlers=sysrq kbd event2
N: Name="Logitech USB Optical Mouse"
H: Handlers=mouse0 event3
N: Name="HDA Intel Headphone"
H: Handlers=event4

Note the name of the device and the event. For me it was Logitech USB Optical Mouse and event3 .

STEP 2:Now we need edit the 10-evdev.conf located in /usr/share/X11/xorg.conf.d/ (Exclusively for Ubuntu 11.04 users). To edit the file issue the command

sudo gedit /usr/share/X11/xorg.conf.d/10-evdev.conf

users using earlier versions on Ubuntu need to  edit the xorg.conf locate in /etc/X11/xorg.conf . You can issue the command



sudo gedit /etc/X11/xorg.conf




Once you have opened the file go all the way to the bottom of the page and add the following thing

Section "InputDevice"
Identifier "<name of the device we found in step 1>"
Driver "evdev"
Option "CorePointer"
Option "Device" "/dev/input/<event of your mouse>"
Option "Resolution" "800"
Option "RelHWHEELMapTo" "Buttons 7 6"

The final thing should look like

Section "InputDevice"
Identifier "Logitech M100"
Driver "evdev"
Option "CorePointer"
Option "Device" "/dev/input/event3"
Option "Resolution" "800"
Option "RelHWHEELMapTo" "Buttons 7 6"

And it is done. If you want you can also modify the resolution of the mouse. Caution: It may stop the mouse from working.

If you have any queries feel free to post a comment.
