Touchy Touchpad [Solved]

[CharlesV]

If you remove the mouse, and then lift your hands off the palm rest... does your track pad work better ?
Smoothly, no issues?
Now try with the palms resting on the palm rest. If this NOW is an issue, but works when your palms are NOT on the rest...then you may have to identify what that area is and to detect it.

That trackpad MAY need some custom libinput values....
if you look at the following file, and make sure to have these entries in it.. you may prevent issues with PalmDetection issues.

Code: Select all

/etc/X11/xorg.conf.d/30-touchpad-libinput.conf

Code: Select all

Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
        Option "Tapping" "True"
        Option "PalmDetection" "True"
        Option "TappingDragLock" "True"
EndSection

I am also seeing this config for some people... you might that first one, then if that doesnt help, the second one.
( Make sure to reboot after changing it and test well...

Code: Select all

Section "InputClass"
  Identifier "touchpad"
  Driver "libinput"
  MatchIsTouchpad "on"
  #Option "ClickMethod" "clickfinger"
  Option "Tapping" "on"
  Option "TappingButtonMap" "lrm"
  Option "EmulateThirdButton" "1"
  Option "EmulateThirdButtonTimeout" "750"
  Option "EmulateThirdButtonMoveThreshold" "30"
  Option "PalmDetection" "1"
  Option "TappingDragLock" "1"
EndSection

In the first code section you have put

Code: Select all

Option "PalmDetection" "True"

And in the second you have put

Code: Select all

Option "PalmDetection" "1"

Why this difference? Does PalmDetection disables the touchpad if external mouse (USB or Bluetooth or Wireless) is connected?

It seems like it may work a little better?!?
Which Terminal should you use and do you enter the entire code or one line at a time?
Examples:

I believe the correct syntax is to use "True" ... however, I have seen "1" used in many places. Both of these configs I have seen in various places, not sure which one is really 'correct'... but people say they both work.

Examples:

No terminal. You need to edit the following file (I suggest using featherpad )

Code: Select all

/etc/X11/xorg.conf.d/30-touchpad-libinput.conf

and make sure that file has those lines that I posted. THen reboot

Alright! the file below to which one? What app does one use to Edit this file? Menu Editor ? or find it? confused.
/etc/X11/xorg.conf.d/30-touchpad-libinput.conf

The Tech is guessing by saying this. It may be an issue with the trackpad controller circuit on the motherboard. Nothing can be done about that except changing the motherboard. But that’s too costly.

K.. stop 'guessing' what that tech says. And READ my post!

use featherpad to edit that file.

In Thunar, go to the file, edit it using featherpad. After editing save it and reboot

[Gigahenry007]

Hows this? Next step?
Thank you for your patience...

[CharlesV]

Well.. it looks like you are trying to overwrite the file with a new one, instead of editing it. But, as long as your file contents are one of the ones I posted, I think you will be just fine.

Save the file, then reboot and test it all out.

I haven't done anything yet! Just showing where I landed and I'm not sure what you mean by Editing that file ?

From Post #21 - 26 you shared different Codes. I didn't copy those or did anything with them. YOU did tell me that I wasn't supposed to use Terminal and to us Thunar later on.
I'm really sorry about the confusion!!!
Please advise.

THANK YOU!
