I have an ASUS mouse (ROG Gladius 2) but the extra mouse buttons are not recognized as mouse buttons in Ubuntu. With the software from ASUS (while working in Windows), I can assign a keyboard or mouse functions to the extra mouse buttons, but I cannot simply say this extra key needs to be an extra mouse button so that I can use it in Ubuntu.
When I assign to the extra mouse buttons a multimedia function like turning up the volume, it also works in Ubuntu. Changing DPI with a mouse button also works.
The keyboard functions are not working. Like emulating pressing Control or a letter. It works on Windows but not on Ubuntu.
While using xev, it noticed that the mouse buttons aren't recognized at all in Ubuntu as mouse buttons. In the past one could download btnx - Button Extension but this software is not available anymore.
So my question is, what is needed to get Ubuntu torecognize all my extra mouse buttons as extra mouse buttons?
