I tried once to contribute a fix to be able to use the track-pad on my laptop many years ago. But it was not accepted as the maintainer claimed it was an problem in userspace that did not process out of order events correctly. Despite none of the other drivers sent the events out of order. I had no intention to fix the problem on X11 (the only userspace for this at the time), so I used the patched kernel driver locally until I stopped using that laptop. https://bugzilla.kernel.org/show_bug.cgi?id=43591 https://lore.kernel.org/all/1340829375-4995-1-git-send-email...
