Enable full touch support for ELAN0600 touchpad

[Alessio Treglia]

Hi,

ELAN0600 lacks full touch support if not registered with elan_i2c.ko.
I've got in touch with Benjamin Tissoires, who kindly provided me with a two-lines patch that fixed the problem for my Lenovo Yoga 3 11 [1]. He has afterwards made the patch publicly available at LKML [2].

Some more information follow, the bug is still reproducible with the latest Vivid's and mainline kernels:

News anybody? Any chance to see this fixed before Vivid goes live?

[max (p-max-s)]

Apologies if this isn't related, but I have one of the new Asus X205TA computers and it reports having a Elantech touchpad with the following entry in /proc/bus/input/devices:

I: Bus=0018 Vendor=04f3 Product=0401 Version=0100
N: Name="ELAN0100:00 04F3:0401"
P: Phys=
S: Sysfs=/devices/platform/80860F41:03/i2c-11/i2c-ELAN0100:00/0018:04F3:0401.0002/input/input9
U: Uniq=
H: Handlers=mouse0 event9
B: PROP=0
B: EV=17
B: KEY=30000 0 0 0 0
B: REL=103
B: MSC=10

The only difference in the ID from the original post in this thread is that it's Product=0401 instead of Product=0400.

I thought I'd mention it in case it's a two-birds-one-stone kind of scenario. I'm happy to help test out a fix on my hardware. Currently Ubuntu 15.04 only recognizes it as a Mouse, not a Touchpad, so I only have L + R click but no multi-touch interactions.

[Alessio Treglia (quadrispro)]

This should be fixed in linux 4.2-rc4

https://github.com/dtor/input/commit/6ccfe64c770139675a080ee5029ded7d89d9ea0d

[encyd (encyd)]

Unfortunately it looks like this didn't make it into 15.10/wily:

The id for the elan device isn't in the ignore list:

http://kernel.ubuntu.com/git/ubuntu/ubuntu-wily.git/tree/drivers/hid/hid-core.c

[Andy Whitcroft (apw)]

That fix only actually hit mainline in v4.3-rc1. So it missed wily via natural means. Will ask someone to get a test kernel together for this.

[Joseph Salisbury (jsalisbury)]

I built a Wily test kernel with a cherry pick of commit 6ccfe64. The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1439111/

Can you test this kernel and see if it resolves this bug?

Note, you will need to install both the linux-image and linux-image-extra .deb packages.

[Alessio Treglia (quadrispro)]

Works like a charm, thanks!

[Joseph Salisbury (jsalisbury)]

I just submitted an SRU request for Vivid and Wily.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-wily' to 'verification-done-wily'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

Tested on both wily and vivid. Thanks!
