"Newer" synaptics touchpad support a new mode where they can report more information to the host. In this mode, there is a different packet format for tracking extra data from the touchpad, including a wheel encoder (mousewheel) if available, and multitouch finger tracking. This mode is documented in the Synaptics touchpad interfacing guide (Synaptics document 511-000275-01 Rev. B), but was not yet implemented in our driver. It should help with detecting multiple fingers, or finger position on clickpads to determine right or left click. This change implements the following items from the Synaptics interfacing guide: - Cleanup and clarify the code for features detection to properly report clickpads - Enable "extended W" mode if supported - Process extended W values 0 (mouse wheels, reported in the touchpad_event structure and could be used by input_server for scrolling), 1 (secondary finger), and 2 (finger count) - Fix handling of wValue, which is not always a finger width - Add handling of vValuen which indicates the finger width when wValue doesn't Overall, this should provide the movement_maker with a better picture of what's happening. Also improve tracing to show received packets and the corresponding WValue since that's an important value in identifying which type of packet it is. Unfortunately I currently don't have a laptop with synaptics touchpad to test this with.

Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
Compiling Haiku
See ReadMe.Compiling.
Contributing
Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!
