I upgraded the various Xorg packages on my system to the version in Sid
(still a Jessie install as at the moment I cannot upgrade my laptop to
Stretch, nor I can create a new partition), but I cannot reproduce this
problem with neither 340.96-3 nor 352.63-1.

In your reportbug output I can see these lines where we grep
in /etc/modprobe.d files:

/etc/modprobe.d/i915-kms.conf:# PABLO: creo que lo puse para el
bumblebee, pero ahora lo quito para intentar tirar directamente con
nvidia, que no meta el driver de intel y no me cree conflicto
/etc/modprobe.d/pablo-prohibir-intel.conf:# PABLO :evitar que los
drivers de intel entren en conflicto con los de nvidia

Do you have any particular custom blacklists/configurations for the
graphics modules?

Kind regards,
