Libinput, the free open-source input library and driver, released new 1.29.0 version few days ago.<\/p>\n

Libinput is a popular input library, that’s default in Ubuntu, Fedora, and many other Linux Distributions, for handling mice, keyboards, touchpads\/touchscreens, and other input devices.

The new release of the library introduced new libinput debug-tablet-pad<\/b><\/code> command line tool. As you see in the screenshot above, it shows an interactive interface showing the values when you press on buttons or rotate the screen. This is useful for debugging, scripting, or even remapping purpose.<\/p>\n

For tablet tools with an fixed eraser button, this release added new set of configuration options, allowing to either configure that eraser button to be a regular button or even disable it.<\/p>\n

Libinput 1.29.0 implemented an internal plugin pipeline<\/b>, preparing the way for public plugins, planned for next 1.30 version.<\/p>\n

The biggest internal change is the implementation of an internal plugin pipeline. Kernel evdev event frames are now passed through a pipeline of plugins that can modify and\/or emulate additional events and frames in the process. This allowed us to move a few internal features to plugins, making them more self-contained and easier to maintain.<\/i><\/p><\/blockquote>\n

The release also introduced new heuristic for detecting inadvertent scroll wheel movement, resulting in better responsiveness for most devices.<\/p>\n

It fixed jerky motion and cursor jump issues on some Asus “ASUE…” touchpads. And, it now detects virtual devices (e.g. uinput) and disables some internal features (e.g., the scroll wheel heuristics and tablet smoothing).<\/p>\n

There are as well many new quirks added\/updated in the release for particular input devices. They include:<\/p>\n
