So the setting in question is found in manjaro by going to start button>system settings>input devices>touchpad then to the pointer motion tab. The setting in question is the noise cancellation, I think by default it was set to 8 for vertical and horizontal. Not sure of the specifics, but basically you could select 8 units of movement before the cursor would move, causing great frustration. I changed both settings to 0, which made a vast improvement. I also slowed down the cursor having minimum speed at about 75% of the way to the first notch, maximum speed 25% past the second notch, and and acceleration 25% past the first notch. Change the settings, click apply at the bottom right and breathe a sigh of relief.
I was so happy to read that you found a solution for the touchpad issues, but...
I've tried applying your recommended settings, but I'm unfortunately still having the original issue: dreaded touchpad delay upon initial finger movement.
Actually, Xfce doesn't provide the settings you've described, so I've introduced the following additional configuration to the X synaptics driver:Code:
Option "HorizHysteresis" "0"
Option "VertHysteresis" "0"Sadly, the initial touchpad delay remains with these settings in place, i.e. they made no noticeable effects on my first-batch ISO PineBook Pro.
I've also tried "1" and "10" as the values for these two parameters, still with no noticeable effects.I've verified that the correct settings were applied, using the xinput utility, and yes, the value of the "Synaptics Noise Cancellation" property was already correctly set to "0, 0", as displayed by xinput. Anyway, I've tried re-applying the settings using the xinput utility:
Code:
xinput set-prop "HAILUCK CO.,LTD USB KEYBOARD Touchpad" "Synaptics Noise Cancellation" 0 0Sadly, this also made no noticeable effects, but that was already expected.
As a note, the default value of this property was "8, 8", as displayed by xinput.Going further down the rabbit hole, I've monitored the touchpad events using the evtest utility, outside of X. As a result, no synaptics driver settings were in effect while monitoring the touchpad events, which makes it possible to determine the real nature of the initial touchpad delay.
Below are the excerpts from a few outputs generated by executing the following command on tty1 (complete outputs are attached to this post):

Event: time 1622833543.365692, -------------- SYN_REPORT ------------Based on these three excerpts, it should be safe to conclude that the trackpad firmware has a bug that introduces a delay upon the initial finger movement, as decribed below. As a note, this conclusion isn't new, more than a few forum members have already concluded the same.
Thus, I have to ask you this: are you absolutely positive that you no longer have the initial touchpad delay? It manifests as having no pointer movement when you touch the touchpad with your finger and start sliding the finger across the touchpad, horizontally for example. Then, continuing the sliding motion, the pointer eventually starts moving, but the short initial finger movement is lost, so to speak. That's the dreaded delay.
