I can use my touchpad with my thumb, but not with my short finger. It is as if the area of contact between the fingers and the pad required to register movement/click is too large. How do I fix this?

Output of xinput shows three pointer devices:

Virtual Core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ AlpsPS/2 ALPS GlidePoint                  id=11   [slave  pointer  (2)]
⎜   ↳ ALPS PS/2 Device                          id=12   [slave  pointer  (2)]

  • Please edit your question and add output of uname -r terminal command.

  • @Pilot6 I've updated the question. Aug 7, 2015 at 10:00
  • Is GlidePoint the touchpad? Then please post output of xinput list-props 11. You can find out which is the touchpad by trying xinput disable 11 or xinput disable 12. The one that stops touchpad from working is that. You can enable them back.

  • @Pilot6 It's GlidePoint(id=11) I've added output to the question. Aug 7, 2015 at 15:24
  • I think this is a kernel driver issue. Try kernel 4.1 or 4.2 from kernel.ubuntu.com/~kernel-ppa/mainline

I am convinced with a solution that provided by ubuntu community as it worked for my ubuntu 14.04 (on hp14-notebookpc).It is just adjusting the sensitivity as follows,

Open a terminal and xinput list and note down your pointer device number.

Setting sensitivity:

Apply xinput --set-prop [device number] "Synaptics Finger" 50 80 257(use values that suits).Now the sensitivity will be readjusted. The higher you set the numbers the more force is needed to make an event fire. And the less sensitive the touchpad get.For the accurate information visit "https://help.ubuntu.com/community/SynapticsTouchpad".
