Did this issue just start happening after a recent upgrade or update?

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.18 kernel[0].

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.

working nice with kernel: 3.17.1-031701-generic

[penalvch (penalvch)]

Renato Araujo Oliveira Filho, the next step is to fully reverse commit bisect the kernel in order to identify the fix commit. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?

Once complete, please then mark this Status Confirmed.

Thank you for your understanding.

[Joseph Salisbury (jsalisbury)]

Can you also give the latest 3.16 upstream stable kernel a try, to see if the fix already made it's way through stable updates:

I am also having this problem with this model. In addition, right click does not work, even from boot up. Also, I am unable to move the cursor while the left click is pressed. These issues mean I am unable to drag icons, unable to resize windows, and unable to suspend my computer.

Is there a fix in the works or should I return the computer?

[penalvch (penalvch)]

Hankie Shahs, it would be most helpful if you filed a new report via a terminal:
ubuntu-bug linux

[Hankie Shahs (shaansweb)]

ok, submitted

[Hankie Shahs (shaansweb)]

Just to clarify, the issue is already fixed in the next (3.17) linux kernal? When can we expect a stable version of the kernal to be released?

[udude (igal)]

 I've installed the 3.18 kernel (on Ubuntu-Gnome 14.10) and indeed the problem went away, for the most part...

The touchpad was unresponsive once after resume (it was yesterday, yet to be seen if I can reproduce this).
