No, when I press ctrl+alt+Fx all frezes, ping to this machine stop to
respond too.

the xorg.conf file: https://gist.github.com/vinnix/563e41f052de822fe445
and Xorg.0.log file: https://gist.github.com/vinnix/d40a869bbb8e8bffd819
if it may help.

I will thake a look carefuly in the X.org site, try to found something
related.
I also find this interesting URL,
https://wiki.freebsd.org/Graphics/WITH_NEW_XORG ,
at the end of this, a table with something about "VT switching" (what I
believe that is my problem).

If I understand your question well, I am not accessing X by any other
programs. Just using the normal "startx",
directly on the console of the machine in question. The CPU is a i5/4xxx if
that matters.
What I also can see in https://wiki.freebsd.org/Graphics is ["Haswell"
<not supported>, note:
See Update i915 GPU driver to Linux 3.8
<https://wiki.freebsd.org/Graphics/Update%20i915%20GPU%20driver%20to%20Linux%203.8>
].

when X exits, by switching to VT (with ctrl+alt+f1 key) or just exit:

10/stable: the monitor (that is plugged in VGA port) turns the sinal LED as
off (from blue to orange).
11/current: the screen freezes (but also the entire machine as far as I
know, because network stop to respond).

yeah, that sounds a new stuff to me. I will go more deeper in to this
topics, recently I move to -current to
se if I could help others with somes tests, patches, etc..

sure, X.org can do that. Certainly is not a easy task manage delicate code
with "moody" cards.

now I will try two more test, run only with "vesa" driver, and then try
also to plug on TV by HDMI port
(yes, the mother board has 4 video exits: VGA, HDMI, DVI and DisplayPort).
And just see what happens.

thanks in advance for your time and help,
