You have been subscribed to a public bug: 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. ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: bot-comment -- Touchpad not working (Elantech ELAN0618) https://bugs.launchpad.net/bugs/1778534 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
