Default Will Multi-Monitor work with my setup?

Off-and-on for the past two years I've had multi-display working; for
the past year, nada. It worked until an update on my Sid box.


Since then, I've tried wiping my drive and reinstalling Stable, and
swapping out between my three available cards.


A lot of the problem is that I don't know what's the current way to do
things; I used to use Xinerama, but that's been deprecated, and the docs
I've found on xRandR don't answer the questions I have, etc. Another
part of the problem may be that I've got old video cards (but they used
to work!!!).


Here's what I've got:

westk@westek:~$ lspci | grep VGA
00:05.0 VGA compatible controller: nVidia Corporation C51PV [GeForce
6150] (rev a2)
04:06.0 VGA compatible controller: nVidia Corporation NV18 [GeForce4 MX
4000] (rev c1)


I've tried every variation of xorg.conf I can think of (nv, vesa,
nouveau as the drivers; blacklisting nouveau in /etc/modules/blacklist;
Xinerama on; Xinerama off; etc etc etc), and I get one of four results:


* first monitor displays a working X session (at various resolution
capabilities, depending on the driver used) and the second monitor stays
dark


* first monitor displays a working X session (at various resolution
capabilities, depending on the driver used) and the second monitor shows
the video card's splash screen but doesn't participate otherwise as an X
screen.


* same as above until I open an app a half minute after the screen
appears (or maybe it's just a half-minute after the screen appears) and
the machine locks up hard (at console; I can still get to it via ssh
usually)


* the machine locks up hard before an X screen shows (at console - I can
still get to it via ssh usually)


Can anyone give me a definitive answer that this hardware will work in
multi-display format?


Can anyone give me a definitive answer how to make it work?

When I get the first monitor working, I can run "xrandr -1", and the
screen goes blank for 3 or 5 seconds, and then reports:


westk@westek:~$ xrandr -q
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 4096 x 4096
VGA-1 connected 1280x1024+0+0 (normal left inverted right x axis y axis)
338mm x 270mm

1280x1024 60.0*+ 75.0
1152x864 75.0
1024x768 75.1 60.0
800x600 75.0 60.3
640x480 75.0 60.0
720x400 70.1
DVI-D-1 disconnected (normal left inverted right x axis y axis)
TV-1 disconnected (normal left inverted right x axis y axis)

As far as I can tell, xrandr only sees one card, only sees one monitor.

Thanks for any help!
