Ubuntu 14.04 LTS 64 bit up-to-date. Similar problem.

For me, right button works. Double click doesn't work. ClickPad/TouchPad
is not correctly detected in i2c mode.

Migrated to 3.19 following
https://wiki.ubuntu.com/Kernel/LTSEnablementStack instructions.

Problem continues.

Tested with two computers:

* Manufactured on 2014/07/15 (TMB115-M-C1MW)
* Manufactured on 2015/06/25 (TMB115-M-C2ZM) --> Touchpad i2c mode can be 
disabled at BIOS.
