Description

Summary

See this ticket in miracle-wm for more details: https://github.com/miracle-wm-org/miracle-wm/issues/754

Details

I do not believe that we have this yet, but correct me if I'm wrong. It would be nice to support this out of the box. We can add an item for libinput_device_config_scroll_set_natural_scroll_enabled to make this happen

Prior Art

MacOS, Gnome, etc.

Contributor guide

Research direction
Study how other libinput configuration options (like tap to click) are implemented in Mir's input handling code. Then add support for `libinput device config scroll set natural scroll enabled` and expose it via Mir's configuration interface.
