btnx & btnx-config are mouse button mapper tools for mouse hardware typically from 2000s to 2015 (for newer mice support, we recommend Piper). btnx (Button Extension) is a daemon that enables rerouting of mouse button events through uinput as keyboard and other mouse button combinations.
IMPORTANT: btnx REQUIRES the other package btnx-config, which is the graphical configuration tool for btnx. See btnx-config for more details. There is no installation order between btnx and btnx-config. But to use, btnx should be started first, and then btnx-config should be run.
btnx works best with older mice, typically between 2005 and 2015, but possibly farther or later in time. Later generation mice, typically after 2015, are not as well supported. However there is another remapper program we strong recommend for modern mice: Piper.
btnx and btnx-config was originally written by Olli Salonen. However he has ceased development of the code and one of the repositories is lost. Afraid the code might be totally lost if it is not hosted somewhere, I acquired his blessing to move the project here and maintain it. (Meaning this isn't a fork.) It is now being maintained (albeit limitedly at the moment), particularly for major bugs.

btnx is a daemon that sniffs events from the mouse event handler.
If it recognizes a configured event, it sends a keyboard and/or mouse combination event to uinput. This means you can configure certain mouse buttons to send keyboard and mouse events to your system with or without X.
It is useful for mice with more buttons than window managers can handle. It also means you won't need to manually edit your window manager and X configurations to get additional functionality from extra buttons.
To build on Ubuntu or Debian, you need the following dependencies:
build-essentiallibdaemon-devlibglade2-devlibgtk2.0-dev
On most Ubuntu machines, these are available without needing additional sources being enabled on your apt-package respositories. To install these dependencies, run the following commands on the commandline:
sudo apt-get install libdaemon-dev libglade2-dev libgtk2.0-dev
To build on Fedora or Redhat, you need the following dependencies:
libdaemon-devellibglade2-devel
On Fedora, you may need more if you don't have GNU-Make or the C/C++ compilers (gcc/g++) installed.
To install these dependencies, run the following commands on the commandline:
sudo dnf install libdaemon-devel libglade2-devel
btnx and btnx-config follow the simple GNU-Make conventions for easy compiling, after you have the dependencies installed. Run these commands from commandline:
./configure
make
btnx and btnx-config follow the simple GNU-Make conventions for installing, after you have successfully run the compiling step. Run this commands from commandline:
sudo make install
btnx and btnx-config follow the simple GNU-Make conventions for uninstalling:
sudo make uninstall
The configuration files for btnx are located at /etc/btnx. The configuration file itself is edited using the graphical program btnx-config. You must install and run btnx-config before btnx will work.
After adjusting the configuration to your liking through btnx-config, make sure to restart the btnx service, either through the "Restart btnx" button in the btnx-config GUI or by running this command on commandline:
$ sudo /etc/init.d/btnx restart
