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: [ 1532.892319] i2c_designware 808622C1:03: controller timed out Jan 5 20:55:28 darkslide-notebook kernel: [ 1532.892334] i2c_designware 808622C1:03: Unknown Synopsys component type: 0x00000000 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?
