Look in your /var/log/Xorg.0.log and see what warnings and errors you have.
I am also trying to get dual monitors to work, only I haven't gotten the 2nd monitor to work at all yet.

You only have one Screen line in your Serverlayout. You need one for each screen. You'll also need another Screen section for the second monitor, and a second Device section for the gfx card (you can just duplicate the existing one, but change the identifier of course). You might want "Screen 0" inthe first section and "Screen 1" in the second but I'm not sure if it's mandatory. The Serverlayout would then contain:

i reinstalled the sysrem....
and nv diver, i think i didnt got the driver correct first time.
i only add up "flag" class(dont have in deful) and some options in "Divece" .
Did NOT change ANY thing (only add), all as deful.
works for me...
works very well this time.

new problem: im using two different size of monitor, (15 and 19)
how to set the screens in corret level? Right now the system think both screens top edge in the same level, but it shuold be almost same level as bottom edge(15 one shuold be a little bit higher)

any ideas???

That is the default configuration, both screens are aligned along the top edge.

If you want them aligned at the bottom edge, you just need to tell X where you want the screens to start, so you just specify pixels values for the x/y coordinates of the top left of the screen, e.g. (I get the impression that your 15" is Screen 0 and is on the left, so I'll assume that is the case, if not just reverse the screen numbers):

This assumes your 15" is at 1024x768 and your 19" is 1280x1024, which is what you have in your MetaModes line.
(256 = 1024 (height of 19") - 768 (height of 15"))

but i only have "screen 0"

this is what the xorg.conf looks like, it works very well, except the hight
so where shuold i add the hight config?

And you have dual-head working? Hmmm, I have no experience of doing it like that. I have two Screen/Monitor/Device sections, one for each head. Though, I currently have a Radeon, so I don't know about Nvidia/TwinView specific options. I've used dual-head with a Geforce before with not TwinView, the config seems to be different. Looks like the nvidia driver handles the whole second head config itself.

EDIT:
EDIT: Ignore the rest, skip straight to Electro's post. Oops.
EDIT:

Looking at the nvidia README, the TwinViewOrientation option only supports values of "RightOf", "LeftOf", "Above", "Below" and "Clone". However, you can specify a "panning domain" in the MetaModes, as in

But that will give the 15" a virtual vertical resolution which you can scroll up and down. I'm not sure if that's what you want, but I think that's about the best you're going to get with TwinView. I can't find anything in the README that allows an x/y offset to be specified. If you don't like the panning feature (virtual desktops are generally a PITA), then you might try standard dual-head (i.e. non-TwinView), but of course, then you have separate screens, which may not be what you want either.

In TwinView there is X and Y offsets.

An example from nVidia's README fie:
1600x1200 +0+0, 1024x768 +1600+0

You have to experiment with the values until you like the results.

Hmmm....rereads the README... Duh!

I must've missed that, I only saw the panning malarkey (... @ ...).

could you explen the code more?

does the code in: Option "MetaModes" "1024x768,1280x1024; " ?

what does "+0+0" and "+1600+0" mean?

for example: accroding to my screen, if i want the monitor with 1024*768 lower 10cm, what
shuold the Option "MetaModes" be?

thanx

TwinView is the way i used in windows, both monitor works fine.
i dont really know what does non-TwinView mean, whats it looks like.
and the config for that is more complet.
whould like to try, if that is a better way for use two monitor.

That specifies the offset of the top left of the screen. So you'd want "1024x768 +0+256, 1280x1024 +1024+0".

It uses two separate X screens, so e.g. you can't move window between the screens. With TwinView the screens are merged into one logical screen. Neither is "better", it just depends on what you want.

yeahs, i got it right, thanx.
really take me a while to find out the best value.

how to set two different wallpapers on each screen?

This is entirely dependant on whatever window manger/desktop you use (KDE?). Since TwinView/Xinerama has only one logical screen, the wm has to understand that there are two physical screens and offer the ability to use a different background for each. I use Window Maker and fvwm, so I'm not familiar with KDE/GNOME/etc, I don't know if they support that. In a pinch, I suppose you could combine two images together with montage!

thanx. i just fing the TwinView still not working perfect:
in physicl my two monitor looks like this: one 15, one 19.

but the system think the 15 one has more display area above. like this:
