QJoyPad is a convenient little program with a Qt interface that converts
movement and button presses on a gamepad or joystick into key presses, mouse
clicks, and mouse movement in XWindows. It should work on almost every Linux
system and with any Linux-supported gaming device.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.

sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install QJoyPad, simply use the following command:
