Elantech touchpad without multi-touch Ubuntu 14.04.1

[Mark]

On my Lenovo B50-70 laptop there is a Elantech touchpad installed.
It is working perfectly as a mouse but scrolling, multi-touch, 2 finger gestures are not working.
Many people are reporting this for older kernels. I would like to report this for: Ubuntu 14.04.1 LTS.

Kernel: 3.13.0-45-generic #74-Ubuntu SMP Tue Jan 13 19:36:28 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Ubuntu 3.13.0-45.74-generic 3.13.11-ckt13

There are many workarounds posted like the one below.
It is a kind of bypass using dkms and dynamically add a module.
Some users reporting that the dynamic module does not survive a reboot. This is "fixed" by adding the remove of the psmouse and adding the new psmouse module. The code seems to work perfectly, never the less.

I am wondering if there is a permanent solution in one of the next kernel and would like to provide you information.
In ubuntu 14.10 (32 bit) it is working.

I looked on the ubuntu store and found: gpointing-device-settings 1.5.1-6ubuntu2
It has selection boxes for emulation of horizontal/vertical scrolling but it is not working.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1423704

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Joseph Salisbury (jsalisbury)]

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 v3.19 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.

Thanks for the quick reply.
I ran: apport-collect 1423704. Data should be available now.
Set status to confirmed.

I have some information that might helpful.
If use: 'xinput test 12' I can see the mouse movements codes like "motion a[1]=501" on screen.
If I use 2 fingers, there are no codes at all. The event is not recognized.

The bug was found after a fresh new install of Ubuntu 14.04.1.
Before I was testing with the 14.04.1 32 bit kernel. I was working there.
At this moment I'm not able to verify if this is solved in the upstream kernel 3.19.

> Joseph Salisbury

Tried to built kernel 3.19. Only with with errors.
However it was efi registered and showed up in Grub. But it is was not bootable.
'kernel panic -not syncing: No working init found'

[Mark (mark-delta-echo)]

Scrolling with two fingers IS WORKING!!!
Thanks a lot!!!

Scrolling was all what was missing. Was it integrated into the new kernel?
The only change I did was: Software & Updates -> Tab: Other software -> select "Canonical Partners"
I did not change the BIOS yet.

Updated Lenovo BIOS to ver 2.08

Checked current BIOS version with command: 'dmidecode' under Ubuntu.
The Lenovo BIOS flash utility is a Windows executable. Since my laptop is dual booting I could use Windows to update the BIOS.
After flashing the BIOS you have to enter the BIOS and set GRUB back as the first bootloader. Initially it is only booting Windows.
You have to change it. Now it is running under:

Version: 9DCN28WW(2.08)
Date:10/14/2014
Bios Revision: 1.40
Firmware Revision: 2.40

The Elantech mouse pad with 2 finger scrolling is still working.
