the M-XT3DR model is NOT fully functional in Linux out of the box; the rightmost button isn't detected at any level, and “right click” comes mapped to the middle button.

Otherwise, works in Linux out of the box.

The top left 2 buttons are browser back and forward.

You can remap mouse buttons in Linux using xinput. [see Linux: How to Swap Mouse Buttons]
