Touchpad Woes...

Caltrop · 05-22-2019, 01:45 PM

Old Dell Laptop Linux system died...
New HP Laptop system died...
Used Dell Laptop up & running Linux, but...

Installed Mint 18.2 Mate again since it was the only distro I had on CD/DVD.
Plan on other Distro's but I expect I will have the same issue.

Having issues with the Touchpad.

Set the external Mouse to left-hand and of course the Touchpad does NOT!
And now the tap-click is a Right-Click.
The Left & Right Button are default, not left handed.

Problem is on this system is that the Touchpad is NOT listed as Synaptics.

Code:

/etc/X11/xorg.conf.d
does NOT exist

/usr/share/X11/xorg.conf.d
50-synaptics.conf

$ xinput list
$ xinput list-props "DLL0651:00 06CB:2985"
Device 'DLL0651:00 06CB:2985':
...
        Synaptics Tap Action (307):	2, 3, 0, 0, 3, 1, 2
        Synaptics Click Action (308):	1, 3, 2
...

$ cat /proc/bus/input/devices
...
I: Bus=0018 Vendor=06cb Product=2985 Version=0100
N: Name="DLL0651:00 06CB:2985"
P: Phys=i2c-DLL0651:00
S: Sysfs=/devices/pci0000:00/INT33C3:00/i2c-8/i2c-DLL0651:00/0018:06CB:2985.0002/input/input13
U: Uniq=
H: Handlers=mouse1 event13 
B: PROP=5
B: EV=b
B: KEY=e520 10000 0 0 0 0
B: ABS=673800001000003

So how do I configure this touchpad device "DLL0651:00 06CB:2985".

OK, I installed dconf-editor on this new system.
I swapped the tap-buttons around & got them working right.
But there is no setting for the physical buttons, which are still right-hand oriented.

google search string "xinput set left handed touchpad"

Make mouse left-handed and touchpad right-handed
If you look at how it is done, then you can, should be able to reverse the settings to get it to switch to left handed touchpad. I'd make a little executable script with the settings inside and add it to the start up list in settings. as most desktops have this option. you also can make the file hidden so you do not hae to look at it every time you open a file manager by adding a dot (.) in the front of the file name.

https://www.linuxquestions.org/quest...ly-4175619714/

with the search string I used there are more hits to look at as well. replacing xinput with synaptics you might pull up some hits how to do this using synaptics as well. Either way the choice is up to you.

for making sure I get the right ID I add awk and pipes, for example

Code:

#!/bin/bash

[[ -z $1 ]] &&
{ xinput set-prop $(xinput | awk '/HP Touch to Pair Mouse/ {print $8}' | cut -d= -f2 | rev | cut -de -f4 | rev) 'libinput Accel Speed' -0.8 &  } ||
{ xinput set-prop $(xinput | awk '/HP Touch to Pair Mouse/ {print $8}' | cut -d= -f2 | rev | cut -de -f4 | rev) 'libinput Accel Speed' $1 &  }

that is in my home bin so I can adjust my bluetooth mouse speed off the cli in a terminal, you have to piece it together if you use this method to make sure you're getting the right column before adding your pipe to rev and cut it.

the point being you could set it up like that and slap it into a file and add that to your startup, in login, or rc.local even, systemd can still do things like that but using the systemd method to set your touch pad via xinput and startup method.

hmm...

It's a Dell Computer with a funky touchpad name.

This is what I am going to try,
in the file: /usr/share/X11/xorg.conf.d/50-synaptics.conf

Code:

Section "InputClass"
        Identifier  "Synaptics"
        MatchProduct "DLL0651:00 06CB:2985"
        Driver "synaptics"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Option "TapButton1" "2"
        Option "TapButton2" "3"
        Option "TapButton3" "1"
        Option "ClickFinger1" "2"
        Option "ClickFinger2" "0"
        Option "ClickFinger3" "1"
EndSection

Then I might start messing about with 'xinput'.

I have to do that anyway when I hook up an external monitor in Linux Mint.
The mouse & touchpad don't know where they are on the screen.
I remember having to have a script to run at boot to fix things.
Hopefully I can find that backup...?

But for now just trying to get the buttons left-handed.

Great success so far with the external mouse.
It's that darn touchpad giving me headaches.

Which DE are you using? XFCE4 gives me a seperate mouse and touchpad configuration though I can't promise how independent they are.

Dconf-editor allows the same for MATE in org/gnome/desktop/peripherals/mouse and org/.../touchpad. They appear to be independent because one of the settings is to tie the touchpad left-hand setting to the mouse setting.
