The touchpad doesn't work on Lenovo Ideapad 320

[Seldon]

Simply the touchpad doosn't work.
Sometimes i can use it for a few seconds when the OS is just turned on and then it stops. I tried to activate it using the hotkey, but unsuccessfully.
I can use instead my USB mouse, that works perfectly.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.14 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'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Thanks for the answer.

The issue is happening on a fresh installation. Upgrades didn't help. It happens also with the live CD.

The strange thing is that for a few seconds (less than 10) the touchpad works perfectly, then it stops working.

I just tried using the mainline kernel downloaded from the link you provided but it didn't solve the problem.

Thank you.

Please attach `dmesg` under Linux v4.17-rc7, thanks!

[Kai-Heng Feng (kaihengfeng)]

It should be fixed on mainline Linux.

[Seldon (enrico-pascucci)]

Sorry for my late reply.

Linux v4.17 gave me the same identical issue. I could not easily post here at the time because of the AppArmor bug.

Now I reinstalled (x)ubuntu 17.10 on my laptop, and after I upgraded Linux to the v4.15-rc3 from the mainline, the trackpad works perfectly.
