I have been able to make them *both* work (using custom xorg.conf), but not *at
the same time* (under debian)
The working setup (linixmint) does not appear to use any proprietary driver
(i.e.: it uses nouveau for NVidia).
I attach here full lspci and lsmod output (of *working* setup; i.e. LM) in case
they give some hint.

I have a setup with two video cards (intel HD Graphics 4600 +
NVidia GeForce GTX 770) and four monitors (two for each card).
I can see all monitors under Windows, but I can see (active, of
course) only two under debian (on the same card).
I tried several configurations to no avail and finally I gave up :(
Yesterday I discovered another data point:
Linuxmint (I tested the "live" distribution) can drive all my
monitors, apparently with no configuration at all (no
/etc/X11/xorg.conf or similar).
LMDE (Linux Mint Debian Edition - essentially the same
distribution, but based on Debian instead of Ubuntu) has the same
problems of plain debian.
Which card does *NOT* work? Does it require a non-free driver?
[My Debian machine is a laptop so I never used multiple monitors]
I *suspect* problem comes from different options enabled (kernel
config?), but I have no idea how to debug such a thing.
I did a dump of lspci and lsmod on the working (lm) system and my
next move will be to get a similar dump on the non
working(debian) setup.
Is there anything else I should check?
As said: the working system has no explicit xorg configuration.
Please help me; I would hate to leave debian world (I was here
since the beginnings, coming from slackware to "buzz").

Mauro
