Switching between single and twin - the right approach is...?
 

Setup: Quadro FX-1000, 2 x SyncMaster 204B (DVI), KDE, Fedora Core 6.

I need a way to dynamically switch between using only one LCD and boths with twinview, without killing X (thus retaining open applications and work in KDE) if possible.

Having read and read, I am frankly confused as to the multitude of options I seemingly have.

Could / would some kind soul take pity and tell me if the following assumptions are right:

1. Multiple layouts work only by restarting the X-server in between switches, so not what I want.
2. I should keep twinview enabled, even when only using one monitor.
3. I should - instead of layouts - use metamodes, ex.
DFP-0: 1280x1024_75 +0+0, DFP-1: NULL;DFP-0: 1280x1024_75 +0+0, DFP-1: 1280x1024_75 +1280+0;
3a. If so, I should be able to change between the two with <ctrl>+<alt>+<plus>.
4. When not using the secondary screen, I tend to turn it off. In order for this not to be a problem (with detection), I should ensure by setting the connected option to "DFP,DFP".

If someone would confirm or refute the above, I shall be better able to direct my further searching better (and maybe more to the point, exlude what I do not need concern myself with).

I am fairly new to Linux but I am really doing my best to get to gribs with this and reading before asking - I just need the direction clarified a bit.
Thank you for your patience.

Cheers

What I do is just go into the nvidia configuration utility and click on the screen I want to shut off. In the dropdown for resolutions there should be an option for disable. I click that and then a confirm thing pops up and just say ok. When I want to reactivate it I just choose the resolution I want.

Really? That simple? I guess I must have been unlucky then, for when I tried it, it just kept complaining about duplicate metamodes and wouldn't save the xorg.conf. The reason I then went directly to the xorg.conf instead was that appearently lots of people had that problem, but after what you say, I shall give it another go.
I assume that would work with an 'enable' too, then?

I would still be nice to know if my above points are right or wrong, though. You know, just for my own education.
It would also be nice with a keyboard shortcut or two for it...

Thanks for the reply, though. Much appreciated.
