Comment 4 for bug 841219

Lennart: I think perhaps what Omer is trying to understand is why (on your specific machine) mouse-chord/emulation is not enabled by default (it should have been working out-of-the-box on all non-Apple machines, and non-ThinkPads, and that having been the case for several years). This is one in the X server, which is a much lower-level than the window manager.

Could you possibly help clarify a couple of points:

  1. Does left+right (middle click emulation) work in other applications. Eg. can you use it for scrolling in Evince?
  2. Did left+right (middle click emulation) previously work automatically on the same hardware under a previous release of Ubuntu?
  3. Are there any preferences that yourself, or another user on the machine, have configured in the process of attempting to resolve the non-working left+right (middle click) emulation?

The main thing is to ascertain whether this is a particular machine (a particular touchpad), or a wider issue. I believe that "Incomplete" in this case refers to needing to fine out more information first, here that means whether fully understanding the extent (scope) of the problem that you've discovered.
