Public bug reported:

The buttons on my laptop touchpad are not functioning correctly under
Ubuntu 14.10.

The laptop is a HP Stream model 11-d008tu. The trackpad is all one
section and does not have separate visible mouse buttons. When running
Windows 8 clicking the bottom left section of the trackpad causes a left
click action, and clicking the bottom right section of the trackpad
causes a right click action.

Under Ubuntu the behaviour is as follows:

- An optical USB mouse plugged into the laptop works normally IF the trackpad 
mouse buttons are never used.
- Clicking the left or right button sections of the trackpad does NOT result in 
any left or right click action occurring (e.g. opening right click menu).
- After trying to perform a left or right button click using the button section 
of the trackpad, any left or right click from the USB mouse does NOT work 
anymore if clicking on an application window. They do however work if clicking 
on the Unity launcher sidebar. This problem is fixed after a reboot.
- Using basic click touchpad gestures that are on the main section of the 
trackpad work normally (i.e. single finger tap to left click, two finger tap to 
right click, two finger drag to scroll).
- Other multitouch touchpad gestures do not work (e.g. 3-finger pinch or hold).
