[SOLVE] ASUS K450LD with FOCALTECH Touchpads

Narga · 2014-07-03 09:47:08

I've bought ASUS K450LD then reinstall Arch Linux but the system can't identified touchpad and I can't make it work. I went to look at the pnp ids instead, as listed in this line of dmesg:

00:09: Plug and Play ACPI device, IDs FLT0102 SYN0a00 SYN0002 PNP0f03 PNP0f13 PNP0f12

The id telling us what sort of device you've is the FLT0102 pnp-id. After downloading Asus' latest windows touchpad drivers, and looking at the .inf files shipped with those. I've managed to finally identify your touchpad manufacturer. What I've learned is that there is a new touchpad manufacturer on the market now called FocalTech
I found no information about this touchpad, what's can I do now? Plz help me!

As a good faith reply, and because it was otherwise off-topic, here's a continuation of the discussion for the Focaltech touchpad first started on my AUR package.

As previously established, you have a Focaltech touchpad that identifies as FLT0102.

It seems the newest linux kernel (4.0) now has some (complete?) support for Focaltech touchpads.

http://lxr.free-electrons.com/source/dr … ch.c?v=4.0

You (Narga) have said:

it's works but missing (wrong) two-touchs to open context menu (right click), when I make two-touchs it's show me as scroll the middle button.

This leads me to believe that the driver actually works.

There are two things I would like you to try.

First, see if the touchpad responds properly to multiple touches.

For this, install mtview-git.
You will need to start it from your X11 session with sudo, as it needs to appropriate (temporarily) the whole touchpad device.
It will as for which device you want to use, you will want to use the Focaltech device.

~ ⃲ sudo mtview

A window will open and touches on the touchpad will register as blobs of colors in the window, relative to where you touch. Try using multiple fingers at the same time, it should show multiple blobs if the touchpad "properly" works with multitouch.

Secondly, try to see if the touchpad is recognized by synclient, which is the protocol used by the kernel to configure most touchpads. I know my Elantech and my ALPS touchpads both used that protocol.
The synclient binary is provided by the xf86-input-synaptics package.

~ ⃲ synclient -l | grep -i tap

If your device is not recognized, it will output something like this:

~ ⃲ synclient -l | grep -i tap
Unable to find a synaptics device.

Otherwise, it will output something like

~ ⃲ synclient -l | grep -i tap
    MaxTapTime              = 180
    MaxTapMove              = 163
    MaxDoubleTapTime        = 100
    SingleTapTimeout        = 180
    TapButton1              = 1
    TapButton2              = 3
    TapButton3              = 2
    TapAndDragGesture       = 1

In this case, TapButton1 is linked to mouse button 1, TapButton2 to 3, and TapButton3 to 2, which is I believe 1-finger tap to left click, 2-finger tap to right click and 3-finger tap to middle click.

Then, if all of this works, your DE will influence the configuration of the touchpad, XFCE, Gnome and KDE all have their touchpad options and others too should.

So, please try both things, report on the outputs, and follow up with what Desktop Environment you use. Thanks.

Aweasome, I follow your guidelines then my touchpad works flawlessly with small modification to switch TapButton2 <> TapButton3. Now, I'm continue researching on Touchpad Wiki to make it better.
