I have a mouse with lots of buttons, but it's not a mainstream make like Logitech. For Windows, I have a driver that lets me assign actions like close-window (Ctrl+W) or next-tab (Ctrl+Tab), but I don't have a Linux driver. Since Linux is so flexible, I thought perhaps there is a general way to do this, regardless of brand?

Update: Based on input from Cyrex, I installed and ran sudo apt-get install btnx which found several but not all mouse buttons.
Found: left, right, wheel, wheelclick, thumb fwd, thumb back.
Not found: wheel left, wheel right, thumb middle button.
Vendor ID is 0x04d9, Model ID is 0xa015.

Update 2: In System>Prefs>Mouse there's a lightbulb icon for testing double-click speed. Every working button can turn the bulb on&off, but the missing buttons can't. It would seem that Ubuntu isn't aware of these buttons and thus doesn't register their clicks. I guess I need to hunt for a driver, though a mainstream mouse is probably the easier way.

Please explain what mouse button 9 is. – spudowiar Oct 1 '12 at 19:13
@mateo_salta Got that in seconds before me. – spudowiar Oct 1 '12 at 19:14
Do you use Unity? – int_ua Oct 1 '12 at 19:15
What make and model is it? – spudowiar Oct 1 '12 at 19:19
@int_ua Yes, I strive use a system configuration as close to the default as I can tolerate. – ændrük Oct 1 '12 at 19:23

If all buttons are detected correctly then you can install btnx:

sudo apt-get install btnx OR sudo aptitude install btnx

Then go to: Applications -> System Tools -> Btnx

It has support for many types of mice

I tested my mouse with btnx but it didn't recognize all my buttons. Does this indicate a problem with my mouse (driver?) or with btnx (unlikely I guess)? – Torben Gundtofte-Bruun Jan 4 '11 at 20:57
Am guessing between. Maybe the mouse module is not detecting the mouse correctly so btnx does not either. Can you actually click all the buttons and see if a programa recognizes them, like the click test in the mouse settings. – Luis Alvarado Jan 4 '11 at 21:43
I'm selecting this as the correct answer because btnx allows me to instantly test each mouse button - this proved that Ubuntu simply isn't aware of the extra buttons. I need to get a linux-friendly mouse. – Torben Gundtofte-Bruun Feb 9 '11 at 7:34
btnx can not be found - has the package changed name? – northben Sep 10 '13 at 21:31

I have a MX Anywhere "M-R0001"

I use my forward and Back buttons as Copy and Paste.

1) All buttons are detected with last kernel... at least with

uname -a

3.8.0-25-generic #37-Ubuntu SMP Thu Jun 6 20:47:07 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

2) So, basically, you only need to map those buttons with desired actions. How to know with button is pressed and the correspondent numeric code? Well, you can use the 'xev' program:


This program is a key and mouse events sniffer. When it's running, you can see a window in which you can press mouse buttons and see if they are detected. For example, with the zoom button of the Performance MX you will see something like that:

ButtonPress event, serial 35, synthetic NO, window 0x5800001,
    root 0x15a, subw 0x0, time 64521438, (84,117), root88,144),
    state 0x10, button 13, same_screen YES

that means that 13 is the code for that mouse button. You can try every mouse buttons on your hand ... for easy access, here is the map for Performance MX:

  • Back button: 8
  • Forward button: 9
  • Zoom button: 13
  • Show windows button: 10

the other buttons are well recognized and you don't need to map to actions.

3) Now, you need to install a little program to re-map mouse and keyboard inputs. The magician is 'xbindkeys' ... the easy installation is using:

sudo apt-get install xbindkeys

4) Once installed, you can do the magic. The idea is configure the mouse buttons to send key combinations to activate other desktop functionalities (as the matter of fact, xbindkeys can be used for execute any other program when you press a mouse button). In KDE you can do that with Ctrl+F10 keys combination. The point is create a xbindkeys' configuration file to do the job.

5) To create the configuration file, just run the following command:

xbindkeys --defaults > $HOME/.xbindkeysrc

6) And we need to edit the file to specify your button's mapping:

gedit $HOME/.xbindkeysrc

7) We need to add our button-to-key configurations. For example, I have the following:

# Back changed to Copy
"xte 'keydown Control_L' 'key C' 'keyup Control_L'"

# Forward
"xte 'keydown Alt_L' 'key Right' 'keyup Alt_L'"

# Present desktops
"xte 'keydown Control_L' 'key F8' 'keyup Control_L'"

# Present windows
"xte 'keydown Control_L' 'key F10' 'keyup Control_L'"

8) There was a new requirement. the 'xte' program, which basically simulates user key press combinations. Install it using:

sudo apt-get install xautomation

Now, if you run on a terminal something like:

xte 'keydown Control_L' 'key F10' 'keyup Control_L'

that means simulate a Ctrl+F10 keypress. The idea is using xbindkeys to say: "when I press 13th mouse button, send a Ctrl+F10 keyboard press using xte program to generate that"

9) And finally, you need to configure 'xbindkeys' to run automatically on system startup. Startup Applications / Add program button and type '/usr/bin/xbindkeys' on the dialog.

Also, as a note, it's usually easier to grep xev with xev | grep button for mouse buttons.. – Seth Jun 16 '13 at 19:54

Easystroke is a Mouse gesture-recognition application and mouse gesture manager for Ubuntu and Other Linux distribution. it allows user to control ubuntu application with hand drawn mouse gestures or Draw on the Screen. Easystroke work on Tablet PCs, it can be used equally well with a mouse, pen, or even your fingers if you have a touch-sensitive screen.

sudo apt-get install easystroke

If you want installing easystroke via PPA, you can adding a PPA repository, type this command:

sudo add-apt-repository ppa:easystroke/ppa
sudo apt-get update
sudo apt-get install easystroke

For Unity Users : EasyStroke have not used indicator applet yet, so when you run it from menu, you have nothing on Indicator Applet. To solve this problem, simply run these command in terminal:

easystroke -g

It will run EasyStroke and open configuration windows automatically.

Awesome tool :) thanks a lot – Patryk Aug 21 '14 at 21:10

If you install the CompizConfig Settings Manager Install CompizConfig Settings Manager then you will be able to set a lot of window management mouse button shortcuts.

It may take some effort working out which button is which.

In the screenshot I am assigning opening the Super+Tab switcher to a left-click of my scroll wheel.

Easystroke Gesture Recognition is designed primarily for creating custom pointing device gestures, but it can also be used to assign actions to simple button presses.

To use it in this manner,

  1. Open the configuration window.
  2. In Preferences ▸ Behavior ▸ Additional Buttons ▸ Add, select Instant Gestures and then press the desired mouse button in the gray box.

  3. In Actions, click Add Action.

  4. Double-click in the Stoke column and then press the desired mouse button again.

  5. Click in the Name, Type and Details columns to set up an action.

Olli Salonen has his own ppa which needs to be added to your list if you want to install via apt. Here is the info about adding ppa.

Also, this link might help with installing on newer version of Ubuntu since I see Olli isn't active for quite a while now.

and yes this link you provided is what I was looking for, thanks again… – user231354 Feb 23 '14 at 21:02

Btnx is available for download from here.

Source is here: It built and ran on my Linux Mint 13 without problems. Caveat: btnx-config needs to be run with root perms.
