Trackpad Ghost touches after some time. Poweroff is workaround. - erikbotta - 09-29-2020

I have issue with trackpad at PBP. After some hours of work it will suddenly register ghost touches ... and one finger is detected as two ... etc.
Power off and on fixes it for some time.

My X11 trackpad settings:

Code:
Section "InputClass"

        Identifier "touchpad catchall"

        Driver "synaptics"

        MatchIsTouchpad "on"

        MatchDevicePath "/dev/input/event*"

        Option "MinSpeed" "0.25"

EndSection

My additional settings via script:

Code:
synclient MinSpeed=0.25

synclient FingerLow=30

synclient PalmDetect=1

synclient VertScrollDelta=64

synclient HorizScrollDelta=64

I tried both firmwares for keyboard/trackpad
I tried many other settings of Xserver.

This problem isn't from begin of buy so it may be some misconfig.
Anyone can help me?
Thx,
Erik.

I had a similar issue, with some discussion here:

Although it's with a very different configuration than yours.

Yes it is the same issue as I read your discussion.
I tried really a lot configuration with/without synaptics etc.
I think it is a hw issue. With new manjaro, sleep mode also help me so it is quick fix.
After I received 3rd LCD with problem and now this Sad

.
Thx for response. I will follow your thread if anyone find solution.

EDIT:

I was thinking about reseting keyboard by usb bus to fix this.
I tried

Code:
lsusb

Bus 003 Device 002: ID 258a:001e HAILUCK CO.,LTD USB KEYBOARD

sudo usbreset /dev/bus/usb/003/002

after that keyboard is OK, but trackpad is total weird and need restart PBP.
Can you try it? I will try also go back to older firmware not from community.

It's been a while since I've experienced the issue (I'm running manjaro, so perhaps their suspend configuration is helping me here), but if I do I'll try the usbreset trick.

Well, I did see the issue again. usbreset did roughly what you said - broke the trackpad until a restart.
