[gentoo-user] Changing primary monitor on dual-monitor X.org setup

[Aleksey Kunitskiy]

Hi Gentoo community,

I'm new to dual-monitor setups and I have one question to you:
I have Geforce 7950GT graphics card with two independent DVI-I outputs and two 
monitors connected to each DVI out. I configured X.org to use two screens 
separate on these two monitors.
Question: How can I interchange screens between those two monitors? I've 
primary screen always on "first" DVI-out and I want to change it(I want the 
primary screen to be on "second" DVI-out)

Here is my xorg.conf:

Try switching the LeftOf to RightOf.  Is that what you meant?  Or did
you want to plug the monitors into each others' plugs?  In which case

Just switch the Monitor lines here, and switch the plugs.

Yes, I want to plug monitors into each others' plugs, but with one thing  - 
without switching monitor plugs physically. I switched monitor lines there 
but it changed nothing. Screen0 is still on the "first" DVI out and Screen1 
is on the "second" DVI out, I need vice versa

I think that I have to specify in each Monitor section on which DVI out this 
monitor identifier have to be, but I don't know how to do it

Section "Screen"
	Identifier "Screen0"
	Device     "Card0"
	Monitor    "Monitor1"
	DefaultDepth	24
	SubSection "Display"
		Modes	"1280x1024"
		Depth	24
	EndSubSection
EndSection

Section "Screen"
	Identifier "Screen1"
	Device     "Card1"
	Monitor    "Monitor0"
	DefaultDepth	24
	SubSection "Display"
		Modes	"1280x1024"
		Depth	24
	EndSubSection
EndSection

Or, just switch the Device lines.  Each device is a single DVI port (at 
least on my NVidia setup).

Section "Screen"
	Identifier "Screen0"
	Device     "Card1"
	Monitor    "Monitor0"
	DefaultDepth	24
	SubSection "Display"

Nothing changed. Where I am mistaken ? :(

You could try to change the entry 'screen' in 'Section "Device"'

Give this a try, haven't got a chance to test atm but should do what
your after

Section "Screen"
        Identifier "Screen0"
        Device     "Card1"
        Monitor    "Monitor0"
        DefaultDepth    24
        SubSection "Display"
                Modes   "1280x1024"
                Depth   24
        EndSubSection
EndSection

Section "Screen"
        Identifier "Screen1"
        Device     "Card0"
        Monitor    "Monitor1"
        DefaultDepth    24
        SubSection "Display"
                Modes   "1280x1024"
                Depth   24
        EndSubSection

I tried to change "Screen" parameter in section "Device" and "Device" param in 
section "Screen" - none of these two variants work for me :(
