Are you able to get into bios?

There will be a setting that allows you to choose "advanced" as an option for the touchpad. It will probably say something like "Load the I2C driver or advanced features will not work"
Don't change the setting - i just want to know what it is set to at present. (This will affect both Windows and Xenial touchpad behaviour)

I can get in to bios but there is no advanced touchpad setting. I should say that I am running win 10 and trying to get xenial64 to dual boot so I am a bit delayed at present.

I have just got access to a similar model of Acer and I can see what you are describing.

When using Xenial the pad is not behaving the same way it does under windows. I will try to find some settings that make it more stable.

At first glance it appears we need to forget the underlying touchpad click function (ie: full depth press for mouse clicks) as that confuses the multifinger touch sensitivity of the overlying touchpad. (Full depth press only seems useful for lasso/highlight function)

Looks like we need to focus on using the light tap-to-click functionality for registering clicks.

One thing I don't see is how you perform a right click with one finger?

When you get access back to Xenial can you clarify that? Where/how does rightclick operate?

cheers!

Still working on the installation of xenial. The easiest way for right click was two finger click. Will check this when I am back in business.

I now have access to a couple of Travelmates which use similar touchpad/clickpads as the B113 so i can hopefully try various touchpad settings and come up with some useful suggestions.

It is clear that flsynclient is limited in it's scope and does not allow adjustment of all of the underlying synclient parameters - especially when using clickpads. This leaves the user in the position of having to manually adjust the synclient parameters one by one (or by using scripts - which i will post later).

The first problem I encountered was how do I reset the synclient settings to normal after playing with some of the parameters?

I came up with a utility that allows the user to make a backup of the synclient settings before making any changes, and reload them later if necessary after having a play with the touchpad/clickpad adjustments.

The utility appends a timestamp to the backup file so it allows the user to make multiple backups, alter the name to make each one meaningful, and choose which one to reload later (the timestamp helps identify which was the original starting file).

Hopefully it will be self explanatory.

(Even if you normally use flsynclient on other touchpads this utility can still be useful for keeping a backup of touchpad settings)

Thats a useful little utility greengeek, Thanks.
I am still trying to get xenialpup back on the B113 without destroying the existing win10 installation so am out of action still. It has reminded me why I hate windows though.

Hi Number77 - i have been experimenting with various scripts to tame the Acer clickpad and have opened another thread so that I don't clutter this one. I will add new scripts to that new thread as I develop them, and also add more explanatory information as I am finding out quite a lot about clickpad behaviour and multitouch gestures.

New thread here:
