Ubundu 14:04 does not recognize projector after upgrading

[Luca]

Ubundu 14:04 does not recognize projector after upgrading from Linux Kernel 4.2.0-42-generic Linux 4.4.0-45-generic (if within the old kernel works if within with the new one does not go).

Before the update with the lighting of the notebook was immediately recognized any projector and the fn + F8 allow me to move from PC screen to the projector.

Now the same projectors are not recognized at boot Ubuntu and does not work the fn + F8 key.

What should I do?
