Bug Description

For a fresh installed Ubuntu 16 (and 18), touchpad doesn't work for Elantech ELAN0618.

We have modified the struct elan_acpi_id, by adding ELAN0618 to the list of the supported models (in the file drivers/input/mouse/elan_i2c_core.c from the kernel source)

static const struct acpi_device_id elan_acpi_id[] = {
 { "ELAN0000", 0 },
 { "ELAN0100", 0 },
 { "ELAN0600", 0 },
 { "ELAN0602", 0 },
 { "ELAN0605", 0 },
 { "ELAN0608", 0 },
 { "ELAN0605", 0 },
 { "ELAN0609", 0 },
 { "ELAN060B", 0 },
 { "ELAN060C", 0 },
 { "ELAN0611", 0 },
 { "ELAN0618", 0 },
 { "ELAN1000", 0 },
 { }

and then built the kernel, and our problem solved.

Thank you for providing a patch, and making Ubuntu better.

Can you provide some information on the status of the patch with regards to getting it merged upstream? Has it been sent upstream, what sort of feedback has it received, is it getting applied to a subsystem maintainer's tree, etc?

o submit your patch, send your patch with the detailed description/changelog and your Signoff (ending with Signed-off-by: your name <email>), to the emails listed from ./scripts/ drivers/SUBSYSTEM-DETAILS (the is from the kernel sources). Once you have sent the patch upstream and it's accepted, please drop a note here so that we can cherry-pick/include the patch into Ubuntu kernel.

Thank you too for following up the reports here.

Sadly I currently have no access to the system, it was my friend's laptop.

I think it is not yet merged since he said after a kernel update two days ago (proposed by the Software Updater), the touchpad stopped working and he had to install the manually built kernel again using dpkg.
