To the Batmobile! libinput 1.6 is out. Why you would need to get to the Batmobile for that is anyone's guess but you shouldn't give up a chance of driving it around.

This release fixes the slow touchpad bug seen in the two RCs, thus making the world a slightly better place.

libinput 1.6 RC1 is out. Test it while it's hot, this is the one that has the fixed touchpad acceleration code. If you were struggling with libinput on touchpads before, this is your/my chance for redemption ;)

In response to a recent inquiry, I wrote a high-level overview of the synclient tool.

This post describes the synclient tool, part of the xf86-input-synaptics package. It does not describe the various options, that's what the synclient(1) and synaptics(4) man pages are for. This post describes what synclient i...

Statistics/Maths question:

I have a set of 2d data points (time, distance). I can easily calculate the mean and 95 percentile separately for either axis but: how do I calculate the 95 percentile for the combination of both, i.e. 95% of points are less than (t, d)

Or is (t, d) just the tuple for the separately calculated 95 percentiles anyway?

Luckily based on the data I don't have to do this, I can mostly just wing it. Judging by the distribution I'm not sure a line would even be possible (or rather, whether it would be meaningful). But it turns out that using the independent 95 percentile axes is close to what I need to do anyway. Thanks though.

I wrote a post about the future of xinput, xmodmap, xsetwacom and all the other little x* tools that we have floating around. TLDR: they won't work under Wayland.

This post applies to most tools that interface with the X server and change settings in the server, including xinput, xmodmap, setxkbmap, xkbcomp, xrandr, xsetwacom and other tools that start with x. The one word to sum up th...

+Martin Gräßlin I will not ask you anymore. Sorry, if I sounded too brisk. I was hoping for some kind of clarifying statement and your recent blog post did that. So, thank you very much.

On Fedora 25? Try libinput-1.5.1-2.fc25 please, fresh in bodhi now.

All others, the patch below appears to make touchpads much more responsive. Please test, thanks.

libinput 1.6 rc2 is out. Fresh, hot, possibly smelling of greatness.

I'm currently writing test cases like crazy (for the next version) so I merged quite a few more prep work patches than I'd like before a release, so here's another RC. Expect the 1.6 final in a few days.

Here's a writeup of the issues with libinput's touchpad pointer acceleration and how it looks after the patches I just spammed the list with:

The git branch if you want to test it yourself:

Last week I ran a bit of analysis on how users tap on touchpads. TLDR: we can reduce some of the thresholds to provide for a more responsive cursor. More details in the writeup here:

libinput 1.5.3 is now available. Three rather niche fixes, but fixes they are nonetheless. Rejoicing is permitted but not required.

I wish i was a coder. I have hacked a little in python but not a natural... and know very little about C and C++.

I will file a bug report for this. Thanks for the discussion. :) Merry Christmas!
