Public bug reported:

Description:    Ubuntu 14.04.1 LTS
Release:        14.04

Package: It is unclear to me which package is responsible.

Expected Behavior: For the touchpad and/or ELAN touchscreen to have
scroll capability.

Actual Touchpad Behavior: When two or three fingers are put on the
touchpad and a scrolling motion is made (in the center, or at either
side), it causes the mouse to move as if it were being moved normally
sometimes, other times the mouse stays still and doesn't move, but no
scrolling is accomplished and the cursor doesn't change to a scrolling
cursor.

Actual Touchscreen Behavior: The touch screen shows the same behavior,
except there is no case when the mouse stays still, it will always move
as if being moved normally. In addition, the touchscreen's precision is
markedly rough compared to my experience using this same touchscreen on
Windows 8.1 (which has since been wiped from this machine, with
pleasure).

Touchpad Capabilities: Normal mouse movement, right-click using touchpad
button, left-click using touchpad button, tap-to-click using touchpad,
dragging the mouse while something is selected (either with the buttons
or tap-to-click).

Touchscreen Capabilities: Normal mouse movement, single-tap to select,
dragging things after selecting them.

"xinput list" gives me:

 (3)]

I searched the forums and tried all permutations of making sure
synaptics is installed, tweaking settings for the mouse, and disabling
'psmouse', but nothing works.

If any outputs or tests need to be done on my end to give you more
information, please just let me know. I'm happy to help so this bug can
be fixed!
