Enable full touch support for ELAN0100 touchpad

[Daniel]

Hey,

there is no full touch support for ELAN0100. It looks like the system recognizes the pad as a normal mouse. The same problem already appeared for the ELAN0600 pad as you can see here : https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1439111

Hi!

I've got an Asus u403SA notebook with the same elan touchpad, recognised in xinput --list as ''ELAN1000:00". Please let me share my experiences, because I think I'm in the same boat:

In ubuntu 15.10 with stock 4.2.x kernel the touchpad works with PS/2 emulation mode, so this is why multitouch not works. The official support merged in kernel 4.3x, so with this kernel i've got a fully functional touchpad identified in xinput --list as "elan touchpad", but after a while (minutes, sometimes hours) the touchpad completely freezes with this message in syslog:

Jan 5 20:55:27 darkslide-notebook kernel: [ 1531.867948] i2c_designware 808622C1:03: Unknown Synopsys component type: 0x00000000
Jan 5 20:55:27 darkslide-notebook kernel: [ 1531.893399] i2c_designware 808622C1:03: timeout in enabling adapter

Jan 5 20:55:28 darkslide-notebook kernel: [ 1532.892343] elan_i2c i2c-ELAN1000:00: failed to read report data: -110

I think this is NOT the same bug what mentioned in https://bugzilla.kernel.org/show_bug.cgi?id=108581
and in
http://pkgs.fedoraproject.org/cgit/rpms/kernel.git/tree/0014-mfd-intel-lpss-Pass-SDA-hold-time-to-I2C-host-contro.patch?id=d2ede0b2227fc00e3c80bdd4043245332c3047a8

What can I do to help in problem solving? What output you need?

[Kulcsár Gergő (kulcsar-gergo)]

Sorry for my typos, I relaized that my touchpad identifier is "ELAN1000", but Daniel's "ELAN0100".

Do I need to submit a new ticket?

[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 v4.4 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.

[Marco Pedrazzi (pedrazzi2009)]

there are news about this bug??

[Alex Gallardo (elmanko)]

Should I get excited for the next kernel update, in terms of this bug?

[Joseph Salisbury (jsalisbury)]

Does this bug still exist in the latest Xenial kernel?

[Daniel (daniel-uhl-n)]

No this bug is fixed. Thanks you.
