Public bug reported:

This issue happened the second time to me:

A regular update required a reboot since kernel components where changed.
After the reboot the X11 display comes up without the second monitor and
only the upper half of the screen is displayed (screen seems to be double as tall
as the usual screen, looks like stretched).

Switching to the console view, this issue can be solved by installing the needed
kernel headers:

aptitude install linux-generic

installs linux-headers-generic (= 3.13.0.49.56)

Now both (!!) NVIDIA driver module packages can be recompiled /
relinked:

dpkg-reconfigure nvidia-331
dpkg-reconfigure nvidia-331-uvm

After reboot the X11 displays works as expected in a dual-screen setup on
two monitors side-by-side.

To me this looks like a dependency issue with drastic consequences: critical,
but probably easy to solve.
