Public bug reported: 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: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1778534 Title: Touchpad not working (Elantech ELAN0618) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1778534/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
