I wil just say this ONE MORE TIME and then I'll simply stop responding to posts from people who are obviously not interested in helping me, but just want to "put me through the paces":
I am not an NVIDIA Developer, heck right now I don't even work on Linux development at all.
I have 1000+1 other stuff going on in my life, each and every one far more important than to low a res on my secondary Display.
You folks in here might all be the Devil's own when it comes to developing NVIDIA code and you might know each and every little detail about how to retrieve which kind of info from NVIDIA hardware.
BUT I AM NOT!!!
And I'll be damned before I start neglecting the really important stuff in my life, just to end up surfing through each and every sticky post on forums like NVIDIA.

If you think its supposed to be some "right of passage" for a help seeker like me to find out about e.g. "nvidia-bug-report.sh" on our own, then all I can say is that this must not be the right forum for end users like me!
What a demand, to aks for someone to simply state "run nvidia-bug-report.sh and post the result in here" from the get go, rather than telling me off with "go and read all the sticky posts about how to post in here"....

And that's the last I'll say about this topic - because I do have more important things to worry about.

In order that you learn something from this:

People in forums like this are more than willing to help, but expect you to do your homework, i.e. research a bit yourself about your problem. And even if you don't, to follow very specific instructions given or post additional information as requested.

If you don't feel like doing that, you have to buy enterprise support from NVIDIA, a linux distributor or some other service provider.

Let's keep this thread on topic, please. I'm going to start deleting replies that are not specifically related to the problem desperadus described in his original post. If you wish to discuss other issues, please do it in another thread.

You'll need to start X with "startx -- -logverbose 6" as described in the sticky post to tell for sure, but I would suspect that either there is no built-in 1280x768 mode, or it's getting rejected because it has a hsync frequency of around 47 kHz and the valid range you specified is 61 - 73.2. Also, the +1920 is not necessary in the MetaModes line unless you're using TwinView. You should be able to just remove the "metamodes" option from the "Screen1" section, because the Modes line in the Display subsection should take care of selecting the modes for that screen.
As soon as I had implemented the changes to the monitor's frequency (first putting it at 47.0-73.0 and then to 59.0-73.0 [last value from my Windows setup]) you suggested, the resolution on my 2nd display dropped down to 480x640.
No matter what other settings I tried, it was stuck there until I undid the frequency change.

Sorry, but this only makes things worse for me, not better.

It sounds like you just don't have a 1280x768 mode in your mode pool at all. Please set the range back to one that would allow the 1280x768 mode to validate (e.g. 47 - 73), start X with "startx -- -logverbose 6", and then generate and attach a new nvidia-bug-report.log.gz.

I have actually confirmed that under Windoze that secondary display's resolution goes all the way up to 1024x1280.

But even when I adjusted the mode settings to that new (higher) rez, I still ended up with 640x480 with the lower refresh rate.
And with the higher refresh rate I can only get into 600x800 VESA mode, I can never get past VESA rez!

Your new bug report still doesn't have the verbose mode validation log, I'm afraid. Instead of doing "startx -- -logverbose 6" you could also try putting
Code:
Option "ModeDebug"
in the "Screen1" section, then restarting X and generating a new bug report.

Here is the debug log with the "ModeDebug" Option activated...

Well, you changed the requested mode from 1280x768 to 1280x1024, so this doesn't really apply to the former, but 1280x1024 is getting rejected because it's bigger than the default "native" resolution of 640x480. Please add Option "ExactModeTimingsDVI" and try again. You may also need to set Option "ModeValidation" "NoDFPNativeResolutionCheck" to override the size check.

As I'd written I changed the secondary display res to 1280x1024 after I had verified that this what my Windows partition is running it under.
And I don't see why I have to accept any less than what my Windoze partition can do under Linux.

I put these changes into xorg.conf:
Option "ExactModeTimingsDVI", "1"
Option "ModeValidation", "NoDFPNativeResolutionCheck"

I'll report back after my next system reboot if it was successfull.

OK, now it *finally* worked and I'm a very happy camper
The rez on my secondary display is now not just (almost) twice as high, but it also fits the primary display's rez to a T (so I can move windows back & forth w/l losing sight of 'em).

But can you pleaaaase (with a big cheese) explain to me what O just did?
What are the meanings of all those many, many options I've now put into my X11 config file?

Basically, you're telling the driver to ignore what it thinks the native resolution of your screen is supposed to be and forcing it to use what you tell it instead. This is really only necessary when you have a broken monitor like yours -- DVI monitors are required by the DVI spec to return an EDID, so it's not unexpected to get weird behavior with a monitor that doesn't.
