Hello.
I have recently acquired 2 (identical, 4/3 shaped) screens, so I
combined them with my current favorite screen on a computer which
have
2 graphic cards, but it seems that Debian did not enabled the second
card.
I have tried it on a temporary Ubuntu install, and it works fine out
of the box, so Debian must be able to use that 2nd card too. I tried
to install a more recent kernel from backports on Debian just in
case,
but still no luck. Now that I'm thinking about it, I did not checked
what Ubuntu uses as driver, so if it uses NVidia, this could be the
reason, since I'm using nouveau on Debian. But I think that Ubuntu
does not install proprietary blobs by default?
I tried to find a xorg.conf in /etc on both system, no one had it.
There is no Internet access from that computer, so packages are
installed from the Ubuntu DVD I bought 2-3 months ago (14.04 IIRC)
and
from a Debian DVD set I have downloaded at work (7.5, DVDs 1 to 9
IIRC).
Does anyone knows if nouveau is supports a configuration with 2
graphic cards, or do I have to install NVidia's drivers to do the
job?
Does someone have some links to documents which could explain how to
enable that 2nd card?
Note that I think the second card is disabled, because after doing
quick searches in /sys, I discovered that what I suppose to be the
second card directory have a file named "enabled" which contains "0".
But I'm not expert at all when it comes to kernel stuff.
