[Acer Aspire V5-571] Touch pad Doesn't recognise buttons as separate from touch surface

[Niall Brown]

Note that this is advertised as a multi-touch pad. However, using two fingers stops the mouse movement. This report is not referring the absence of muli-touch. It is referring to a problem with regular touchpad usage caused by this problem.

Problem:
The touch pad includes a touch surface and buttons (beneath) all on one touch surface. The entire touch surface can be depressed to click the mouse. The buttons are an extension of the surface and can also be depressed to click the mouse. They are separated into right and left areas. The buttons are functioning for left and right clicks, however, the software is not differentiating between the buttons and the touch surface for pointer movement. Sliding your finger on the buttons results in the pointer moving on screen. Therefore, when resting your finger on the left or right mouse button (as when preparing to highlight text) you cannot use your other finger to move the pointer because the dual input causes the pointer to stop.

What I expected to happen:
The Touch pad should allow you to rest your finger (without depressing) on the right mouse button while still being able to move the mouse pointer.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.9 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hello Joseph,

I am not very advanced but I will try to learn to install the kernel. Can I
try to install the latest upstream kernel on an Ubuntu USB stick that has
persistence enabled? I am worried about breaking my main work install but
am not sure if that will work.

Thanks,

Niall

Niall Brown, as per http://us.acer.com/ac/en/US/content/drivers an update is available for your BIOS (1.22). If you update to this, does it change anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Thank you for your understanding.

[W B (dlabialego)]

The issue still occures with bios version V2.28 (04/16/2014) and kernel version: 3.16.0-23-generic.
BTW I have aspire v5-473P but I think it doesn't make a difference.

[penalvch (penalvch)]

W B, it would help immensely if you filed a new report via a terminal:
ubuntu-bug linux

Please feel free to subscribe me to it.
