[Dr Michael Brooks <1276960@xxxxxxxxxxxxxxxxxx>]

After a fuck-tonne of Googling, I have a temporary workaround:

    sudo rmmod psmouse
    sudo modprobe psmouse


Simply unloading and reloading the mouse kernel module fixes the problem. This seems to be a kernel driver bug.

Title:
  Ubuntu 13.10 upgrade broke click-and-drag

Status in xserver-xorg-input-synaptics package in Ubuntu:
  Confirmed

Bug description:
  After upgrading to 13.10, click-and-drag no longer works correctly
  (system-wide).

  Steps to reproduce:
  * Open a window where you can highlight text
  * Move the cursor to the start of the text you want to select, using the touchpad
  * Press the right-click button and immediately start dragging using the touchpad
  * Eventually let go of the button and stop dragging

  On Ubuntu 13.04 this worked fine.

  After upgrading to 13.10, however, click events are only registered with a large delay. So doing the steps above actually causes the following event sequence.
  * The mouse moves along the drag path
  * The button-down event registers long way into the drag (or maybe at the end of the drag path)
  * The remainder of the mouse motion events then happen
  * The button-up event triggers

  (I verified the event order using `xinput test`)

  Workaround is to wait (maybe about a second) between pressing the
  right mouse button and starting to drag.

  Needless to say, this makes using Ubuntu pretty annoying.
