two monitors, second insists on being startup

uh yes, the mac sees the monitor if it is pugged in, on or not.

but how do I configure to make the mac see the kds as the first/ primary monitor, and the neovo as the second/ aux monitor. ?

that is the core quesiton.

thanks

quote: I mean this; when booting up, with 2 or 3 monitors, one of them will have the gray screen with the apple on it while setting system. unquote

and

quote; (yes the system prefs set the kds to main after start up) unquote

so we see that the problem is after start up, and system sets kds to "main" and then if system sleeps - on wake up some things have moved to the neovo/ "second" screen // that is to say, on wake the system first loads everything as if neovo is first, then applies the sys prefs to make kds #1 and neovo #2.

= because on start up and on shut down, the mac refers to the neovo as the primary, aka the icon which dipicts start up and shut down opporations is on that monitor.

so why does the mac insist on that monitor? no matter which port that either is plugged into?

Thank you for the suggestion;

result of reset & pram x2 / (and only reciently have checked- replaced the pram batt = new)

1. my mouse now functions as new, very responsive, was being intermittantly slow & jerky...

2. no change on screens.

I do repair permissions regularaly as well.

unplug, wait, boot with reset keys , verify screen alocation, put machine to sleep mode, wait 5, wake up with both monitors on =

both come on, kds has only background screen, neovo has all MenuBar, open windows, open programs.

within seconds the MenuBar and open programs jump to kds, however, open folder stayed on neovo.

Objective is that I dont need/ use the second monitor on a regular basis, so why have it draw power? and if open folders keep migrating there,

its just annoying and a challenge to curiosity.

Update: a bit of wierdness, really I cant see how this applies BUT ;

I shut off my bluetooth mouse because it kept gradualy getting jittery, plugged in a wired mouse and the curser now moves as it should.

but also, as I often need to leave the room for a few hours, the computer sleeps. on wake with the blue tooth mouse there was the problems of screen --monitors seemed to be confused as to their assignments --

after switching to plugged in mouse, no more monitor issues. ?

something in the bluetooth system causing what? 👿

ok so I cleaned the mouse eye, checked the batteries and conections, when I put the bluetooth back on line all is well for a while, but especialy after a sleep - the curser begins to get jerky, ...

I like the magic mouse, so now do I get a bluetooth dongle and bypass the internal?

(( right, that change and change back makes sense too ))

Yikes, another update;

the bluetooth magic mouse is fritzy, if it is the mouse or the blutooth in the Mac,

using a wired mouse

but the sleep to wake up is still there ...

for a while I thought it was the vid-card, but it has to be a software related thing. currently running 10.6.8 fully updated.
