Using nvidia-graphics-drivers-experimental-310 drivers *also* fixed it for me!
However, having other machines with the same problem, this did not seem a reasonable solution, so unblocked and removed nvidia-graphics-drivers- experimental-310 using synaptic, and now *nouveau* is the driver in use. In other machines, installed "lubuntu-desktop" and switched to use it, instead of "ubuntu-desktop", even with nouveau. Some people, who did not know what to do nor how to run programs without the launcher, reinstalled the whole system, due to this bug, so I agree with comments that find this a *critical* bug. Autohidden works now with nouveau, but not perfectly: sometimes pointing the mouse to the left edge just show a "left arrow", the launcher only appearing after some attempts. This makes one think that something is wrong with the launcher, either software or configuration.
