Dual monitor question

I am running an Nvidia 5200 card.  I have an LCD panel connect to the DVI port and a CRT plugged into the VGA port.

With this config, I would like my LCD panel to come up as the primary display and used with GDM, with this config, the CRT comes up as the primary.  How would I change that?

Secondly, when X11 boots, the LCD starts out with a resolution 800x600 all the time -- I can manually switch it to 1280x1024 using nvidia-settings but it never sticks for some reason.  What am I missing here?

Thanks in advance...

My xorg.conf looks like this...

Re: Dual monitor question

Cool.  I got it working with:

Section "ServerLayout"
    Identifier     "Layout0"
    Screen "Screen1"
    Screen "Screen0" RightOf "Screen1"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
EndSection

Not sure why it fixed my resolution issue, but rather then using nvidia-settings I used the gnome screen resolution program to set my resolution and told it to make it the default -- odd.

Thanks!
