Thats good to know - at least we can try a bunch of stuff and the system will revert to normal after reboot. Could you perform the following initial tests and report the results?

First, swap across into a clean desktop (no open windows) and try the following:

1) Position the mouse pointer in the middle of an empty desktop, then tap one finger in the centerpoint of the touchpad. (See pic 1 below)
- what do you hear? (click sound?)
- what do you see? (any menu or other visual response?)

2) Position the mouse pointer in the middle of an empty desktop, then tap two fingers in the centerpoint of the touchpad. (See pic 2 below)
- what do you hear? (click sound?)
- what do you see? (any menu or other visual response?)

3) Position the mouse pointer in the middle of an empty desktop, then tap three fingers in the centerpoint of the touchpad. (See pic 3 below)
- what do you hear? (click sound?)
- what do you see? (any menu or other visual response?)

One finger
Tap nothing, push, click also nothing.
Two finger
Tap menu, push click and menu.
Three finger
Tap nothing, push click and nothing.

Can you clarify the difference between "Tap" and "push"? Do you mean that the behaviour is different depending how hard, or how long your fingers are in contact with the surface?

No the effect is the same, either a light tap or a determined push that clicks the mouse button.

So just to clarify - what happens when you put the mouse cursor in the middle of an empty desktop and tap with two fingers? Does the puppy menu pop up?

Yes, two finger tap brings up menu.

Righto, i think i understand a bit better now.

I was assuming that your pad was set up with areas reserved at the bottom of the pad for the left and right clicks - activated by a single finger tap.

However, in reality it seems that your touchpad driver is set to use the entire mousing area for tapping - no reserved area at the bottom.

This means that your rightclick is any two-finger tap anywhere on the mousing area (probably). And leftclick should be any single-finger tap anywhere on the pad.

So maybe the approach we need is to use synclient commands reducing mouse sensitivity, rather than commands addressing button areas.

I need to have another think about this. I need to get your preferred pad behaviour clear in my mind before i suggest what to change.

Greengeek is this a help or a hindrance:
Fatdog64 720 works the touchpad almost perfectly.
It uses libinput as the driver and its touchpad-gui.conf is:

DO NOT EDIT! Used by touchpad settings app.
Section "InputClass"
Identifier "libinput"
Driver "libinput"
MatchDevicePath "/dev/input/event*"
Option "AccelSpeed" "-0.20"
Option "DisableWhileTyping" "false"
Option "HorizontalScrolling" "false"
Option "LeftHanded" "false"
Option "MiddleEmulation" "false"
Option "NaturalScrolling" "false"
Option "ScrollMethod" "none"
Option "Tapping" "false"
Option "TappingDragLock" "true"
Option "TappingDrag" "true"
Option "ClickMethod" "buttonareas"
EndSection

I don't think we have much chance of getting Xenial to operate the same way as Fatdog in this case. They probably use different kernels as well as different configuration methods. Could you post the output on both Xenial and FD of the following command:
Code:
uname -r


..and on FD could you post the output of:
Code:
synclient -l


Also - your conf file output says:
Quote:
DO NOT EDIT! Used by touchpad settings app.
This indicates that FD has a "touchpad settings" app. Do you know what that app is?

- Were you aware that your Xenial touchpad is set up to recognise multitouch? (eg using the two-finger tap to indicate a right click).

- Does FD behave in that manner? (or is it just looking for single finger actions?)

- Is that multitouch behaviour what you are wanting, or do you want two separate leftclick and rightclick button areas defined at the bottom of the touchpad so that you can select left and right clicks with a single finger tap?

- How are your FD buttons set up? (Are you able to tap-to-click anywhere on the touchpad or just at the bottom of the pad?)

Xenial64 says 4.9.58
FD says 4.14.12
On fatdog you have to go in to control panel, select desktop then adjust touchpad. I can't find any app name.
Fatdog has no synclient.
FD does not respond to taps anywhere.
Mouse clicks are on the bottom dead area and respond only to one finger.

In that case I think we should (for now) ignore the idea of having tap-to-click enabled on the Xenial touchpad. We need to find a way to turn off tap-to-click on the majority of the Xenial touchpad and only enable the clicking on the bottom section of the touchpad. We should also turn off the multitouch recognition on the Xenial touchpad (for now at least...)

As far as I can tell:

1) Fatdog is too different to Xenial for it to donate any software or config info.
2) The driver setup in FD and Xenial result in totally different functionality on the touchpads.
3) You like the FD functionality so we should try to duplicate it in Xenial (despite the different driver and config).

I think we should try to make some major changes to your Xenial touchpad behaviour using synclient commands.

Are you ok with that?

First - some testing:

- It is important to know if the behaviour of the touchpad is identical over it's whole surface. In many cases the top right corner has special "rightclick" functions. This is an inbuilt function of some kernel defaults. Please go to an empty desktop, place the mouse pointer in the centre, and try a one-finger click all over the touchpad (paying special attention to the top right corner). The single finger click should create a leftclick everywhere. However - on many clickpads a single finger tap in the region of the top right corner will generate a rightclick instead of a leftclick - and this will result in the puppy menu popping up. Does this happen or not?

- Some threads suggest that your Xenial touchpad will be setup to recognise a "drag/highlight" function. Try this: Open a text document. Press your thumb on the bottom left of the touchpad (normal leftclick area), and use another finger to drag the mouse over some text. Does this work??

I have backed uo .flsynclient.

A click on whole area of touchpad is the same, no menu.
The drag and highlight function does work.

The fact that the drag/highlight function works confirms that your touchpad is running with the multitouch driver enabled. Some users would find this behaviour more useful than the FatDog behaviour - but the question is can we solve the hyperactive mouse without losing these nice multitouch functions. Maybe not.

I still have some questions to clarify in my mind:

Your synclient settings showed:
Code:
RTCornerButton = 2
RBCornerButton = 3


In theory this means that the top right corner of your touchpad is allocated as middleclick when tapped with a single finger. More importantly, it also means that the bottom right corner is allocated as a rightclick when tapped with a single finger.

Could you try this?

We now know that a two-finger tap over most of the touchpad gives a rightclick function (ie puppy menu pops up on an empty desktop) - my question is whether that also occurs with a single finger tap at the bottom right corner. Does the pup menu pop up?

(these bits of info are important because they determine which configuration changes are most likely to work.

*******************************

After you have tested the behaviour above, could you try the following change:

Code:
synclient ClickPad=0


Have your spare mouse handy as this may lock out the whole touchpad - on the other hand it may switch off the multitouch clickpad behaviours and let us configure mouse buttons separately. The question is - can the touchpad still be used for mousing when ClickPad=0

After trying that, set ClickPad back to 1 and try the following instead:

Code:
synclient PressureMotionMinZ=60


This increases the minimum pressure require to move the mouse (previously PressureMotionMinZ=30) and i thought this may reduce the mouse jumpiness you experience when trying to click the mouse button.

Single finger tap does not bring up Puppy menu
clickpad=0:- The touchpad still works but I now cannot drag the cursor on text when a button is pressed.
I couldn't detect any change with synclient PressureMotionMinZ=60, even when up to 100.

Did you have any control over mouse clicking anywhere on the pad when testing clickpad=0? Or was click functionality lost everywhere?

I will be busy with family funeral arrangements for a few days but i am hoping I may have access to a travelmate B115 when i return. Hopefully it will be similar to the B113 and I might be able to spot some settings that help.
