TwinView Monitor Arrangement is Backward, Xorg.conf Changes Not Helpin

Hey all. Just installed Arch this week and liking it quite a bit--but I'm having one major problem.

I have a dual monitor setup, and using the 

nvidia-xconfig --twinview

command got me a desktop on the second monitor. Everything is as I want it--the right monitor is the primary one, the left the secondary. Unfortunately, their arrangement is backwards: To get my mouse to the left monitor, I have to drag it to the right side of the right screen. Here's my xorg.conf:


# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 260.19.12  (buildmeister@builder101)  Fri Oct  8 11:$

# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 260.19.12  (buildmeister@builder101)  Fri Oct  8 11$

    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

I assume the

    Screen      0  "Screen0" Absolute 1920 0
    Screen      1  "Screen1" LeftOf "Screen0"

part is where I would fix this, but no matter what I seem to put in there, whether changing the first line to Absolute 0 0 or the second line to Rightof "Screen0", I can't seem to get anything to change. What am I missing?

My other problem is that I can't seem to run 

sudo nvidia-settings

either. When I try, it just says No protocol specified. ERROR: The control display is undefined; please run `nvidia-settings --help` for usage information."

Any help anyone could give would be greatly appreciated. I've scoured the forums, wiki and Google and I haven't found anything that's worked for me.

Have you tried using xrandr instead?

For example, to get an external monitor to the right of my laptop screen, I would use:

xrandr --output VGA1 --right-of LVDS1

Re: TwinView Monitor Arrangement is Backward, Xorg.conf Changes Not Helpin

Proofrific's solution worked for me till the other day when for some reason my seccond screen became the main screen.
Adding --primary to the xrandr command fixed it.

Here is my new xrandr command.

xrandr --output LVDS1 --primary --auto --pos 0x0 --output VGA1 --auto --right-of LVDS1

fixed it.

To see the names of the screens, their default resolutions and the other resolutions they are capable off run 'xrandr' with no options while both screens are connected.

you don't need sudo for running nvidia-settings.

why do you have two screens defined in xorg.conf?
this is what mine looks like:

EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "TwinView" "1"
    Option         "TwinViewXineramaInfoOrder" "DFP-0"
    Option         "metamodes" "DFP-0: nvidia-auto-select +0+1024, DFP-1: nvidia-auto-select +0+0"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

The output from DFP-0 is displayed below DFP-1 and DFP-0 is the primary screen.

Well, you do need to have sudo if you want to save the settings in nvidia-settings. Maybe the problem with sudo is that you don't have a DISPLAY set? Or if you do, root doesn't have permission? Try running 'xhost +' first to open up permissions.

Re: TwinView Monitor Arrangement is Backward, Xorg.conf Changes Not Helpin

jdarnold, you solution worked perfectly. xhost + opened up the permissions to run sudo nvidia-settings, and then I was able to fix everything from the GUI. Thanks!!!

I also deleted my xorg.conf and wrote the new settings to /etc/X11/xorg.conf.d/10-monitor.conf as described in the wiki: http://wiki.archlinux.org/index.php/Xor … r_settings at the advice of a friend.

(On another note, how do I mark a thread as solved?)
