Some months ago I did a Ubuntu 14.04 to 16.04 upgrade on my Dell Inspiron - 5000 series.

After performing the upgrade I noticed the two finger scroll is not working any more. The option in the settings menu is available and active but the two finger scroll does not work. The other mouse functions on the touchpad work though. Previous questions on this forum did not result in a solution.

Does somebody has some experience concerning this matter? I would love to use my two finger scroll again

thanks

  • If you hold your fingers a bit apart, does it work?

Although I use a wireless mouse, I also upgraded from 14.04 to 16.04 on a Dell Inspiron 17R 7720 SE and the two finger scrolling works perfectly (I just tried it). I'm on Kernel version 4.7.5 with Intel microcode updates though and never tested under Kernel 4.4. I just want to let you know it does work on Dell touchpad under 16.04.

There is a screen you need to go to in System Settings, Mouse & Touchpad to enable two-finger scrolling as this screen snapshot illustrates:

Two Finger Scrolling

Edit 1 - Synaptics Driver Override

Having verified that Two finger scroll is checked and it still doesn't work, we need to dig deeper. Read wiki.debian.org/SynapticsTouchpad. Where it says:

If multitouch doesn't work for you, your hardware may not support it, but you can use the following options to emulate multitouch which allows most of the features to work. Try adding these lines to the Touchpad section:

Option          "EmulateTwoFingerMinZ"  "35"
Option          "EmulateTwoFingerMinW"  "8"

Follow the instructions in the link

  • Hello, these settings have been checked and are all activated. However no 2 finger scroll.

  • Maybe uncheck 'natural scrolling'? I can't test now because I'm on phone.

  • unfortunately unchecking 'natural scrolling' wasn't the solution
