Tap to click not working

[omouren]

With Asus UX501VW, scrolling works great, good job! But I lost the tap to click with this new driver.

Hmm, this is strange, tap to click works for me as usual.

@omouren Can you please run: sudo evtest

and then select the option that corresponds with the FTE1001:00 0B05:0101 device.

This will dump every event sent by that device - which can be VERY verbose. Just try a quick and simple tap and provide the output.

If you need to install evtest - you can install it on Ubuntu via: sudo apt install evtest

All events after a quick and simple tap like you said

Thanks - that's perfect. This shows the driver working correctly. Check in you system settings that 'Tap to click' is enabled.

It should show up now if you go to System Settings -> Mouse & Touchpad

[omouren]

I'm on Linux Mint 18 (Kernel is 4.4.0-47-generic), I already enabled all of these features in my system settings but I think that it didn't change anything...

[redmcg]

Try running: synclient | grep 'Tap\|Finger\(High\|Low\)\|ClickTime'

You can then compare your values to mine:

$ synclient | grep 'Tap\|Finger\(High\|Low\)\|ClickTime'
    FingerLow               = 12
    FingerHigh              = 15
    MaxTapTime              = 180
    MaxTapMove              = 145
    MaxDoubleTapTime        = 100
    SingleTapTimeout        = 180
    ClickTime               = 100
    TapButton1              = 1
    TapButton2              = 3
    TapButton3              = 0
    TapAndDragGesture       = 1

I'm not super familiar with synaptics - but the man page looks comprehensive. Run man synaptics to view it.

An extract from the Tapping section is:

A tap event happens when the finger is touched and released in a time interval shorter than MaxTapTime, and the touch and release coordinates are less than MaxTapMove units apart. A "touch" event happens when the Z value goes above FingerHigh, and an "untouch" event happens when the Z value goes below FingerLow.

Z refers the value of ABS_PRESSURE from the log you provided earlier. So Z was 127 at 1479370989.502468 and 0 at 1479370989.619029. That means your tap lasted 116.561 msecs. Which is less than my value of 180 for MaxTapTime. So on my machine - your tap would have registered.

synclient doesn't work : Couldn't find synaptics properties. No synaptics driver loaded?

What does xinput list-props "FTE1001:00 0B05:0101" show?

[redmcg]

OK - looks like you're using libinput. I've never used it myself so from here on in I'm guessing. But I would try:

xinput set-prop "FTE1001:00 0B05:0101" "libinput Tapping Enabled" 1
xinput set-prop "FTE1001:00 0B05:0101" "libinput Tapping Enabled Default" 1

[omouren]

It works after the first command thanks. But it still strange that Mint can't change touchpad settings.

[redmcg]

Agreed. It is strange. But glad to hear it's working. Enjoy the tapping and the scrolling!

[omouren]

Fixed Mint settings after remove xserver-xorg-input-libinput package.

[ceejayrao]

On my system libinput is the driver, I initially also had the same issue of pointer not working for tap, then after configuring the touchpad settings to enable tap click, every thing started to work.

I am running kubuntu 16.04 with kernel 4.8.3. The only issue I see is that all options to configure the touchpad are not available for change. I need to see how to get that to work or will a different issue when I have gathered all data.

Thanks Jitendra.
