I don't know what proper Launchpad bug report hygiene calls for, but this behavior isn't limited to the 2014 edition of the X1 Carbon. This affects all users of Lenovo laptops that have both a Trackpoint and a clickpad--which is nearly all of their current models for sale. Going by the photos on Lenovo's web site, this behavior also affects the X240, all the current T models (the T440 models and the T540), the Yoga and Helix, the E540 and E545, the L440 and L540, and the W540.

IBM/Lenovo Thinkpad laptops have a "Trackpoint": a red "joystick mouse" in the middle of the keyboard. Historically this is accompanied by three mouse buttons directly below the space bar. One beloved feature: if you hold down the middle mouse button, you can scroll a window up/down/left/right with the Trackpoint. This feature is implemented in X with the "Evdev Wheel Emulation" properties of the xinput driver for the Trackpoint device. The latest Thinkpad laptops (X240, X1 Carbon 2014 refresh) remove the hard buttons, and have a "clickpad" instead of a trackpad. One must use the "soft" mouse buttons provided by the clickpad. But now we have a problem. The clickpad soft buttons are implemented in the Synaptic driver. And the Synaptic driver doesn't support middle- button-scrolling. If I run % xinput --list-props "TPPS/2 IBM TrackPoint" I see property entries starting with "Evdev Wheel Emulation". Setting them on this device doesn't enable middle-button-scrolling. And if I run % xinput --list-props "SynPS/2 Synaptics TouchPad" I don't see those property entries at all. I tried setting them manually with "xinput --set-int-prop" but they were ignored. One of the maintainers of Arch Linux got middle-button-scrolling with a Trackpoint + clickpad to work! But he had to create a new driver. It looks like he started with the evdev driver, and merged in support for the Synaptics and Trackpoint devices. The resulting driver is published here: https://bitbucket.org/esrevinu/xf86-input-evdev-trackpoint It would be fantastic if Ubuntu 14.04 also supported this feature.
