Two Monitors on Nvidia Ion with nvidia driver

[Anton Ertl]

We have some Zotac IONITX boards that we use as X-Terminals with LTSP
with 30" monitors (no dual-link DVI support for Atom chipsets from
Intel, that's why we chose an Ion-based board). Unfortunately, to
drive the monitor at full resolution is beyound the capabilities of
the nv driver, so we use the proprietary nvidia driver. This setup
works fine, except that we still have to find out how to use some of
the cool features of LTSP (the LTSP documentation leaves something to
be desired; I hope to find the time to help there, it's in a Wiki).

Anyway, now we become greedy and want to use some older monitor along
with the newer one (in particular, I have an old monitor that can be
rotated to give me a 1200x1600 display, which would nicely extend the
2560x1600 display of the new monitor:-).

The Zotac board has an HDMI connector along with the DVI connector (on
which the other screen is connected), and I connected the second
screen there. Looking in the Xorg.*.log file, I see that the X server
recognizes two monitors, the one on DVI as DFP-0 and the one on HDMI
as DFP-1. However, the X server starts only displays on the DVI
screen. I tried getting it to display with xrandr, e.g., with the
following command:

xrandr --output DFP-1 --auto --verbose

but this just doesn't output anything and has no obvious effect. I
also tried the --rotate option of xrandr on the other monitor (DFP-0),
but no effect, either. Do you have any hint on how to fix this
problem? Thanks in advance.

About the software we use: We use Debian, and the versions of the
software are:

# dpkg-query -W -f ='${Status} ${Package} ${Version}\n' 'xserver*'|grep =install
=install ok installed xserver-xorg 1:7.3+20
=install ok installed xserver-xorg-core 2:1.4.2-10.lenny2
# dpkg-query -W -f ='${Status} ${Package} ${Version}\n' 'nvidia*'|grep =install
