Xorg for Dual Monitor, problem with left/right

zero-giulio · 2010-05-11 19:47:51

I have problem with dual monitor.

I mean, I create my own xorg.conf, and I post it

As you can see, it for only one monitor (that of laptop).

Now, I have a samsung lcd conencted to the laptop. I want to use it a secondary monitor (the primary being that of laptop).

I tried to set up it by the gui application Nvidia XServer Settings, and it seems to work if I put the samsung on the right, but if I put it to the left (as I would like) it became primary and I was disappointed.

Maybe it's a problem of the gui application.

What can I do?

What do you suggest?

Try configuring it through CLI. What card/driver do you have?

zero-giulio · 2010-05-12 09:16:38

WHat's CLI?

I have a Nvidia Quadro FX 1600.

The nvidia-settings utility should generate a new xorg.conf.

How does it look like ?

Ok, I post my original xorg.conf (just for laptop's monitor) in my first post.

Next I will open NVidia X Server Settings for enabling second monitor with TwinView.
Now I have (as shown in the GUI):

1) laptop's monitor checked as primary monitor, with absolute position at +0+0
2) samsung's monitor with absolute position at +1920+0

(resolution of laptop's monitor is 1920*1200).

The new xorg, generated by NVidia X Server Settings is

The problem is the same of some months ago (I apologize, during this time I did not have arch).
With this configuration everything seems work fine, but I would like to have my second monitor on the left (not on the right).

But,
1) if I try to set "LeftOf" in second monitor setting, the result is that it's became the primary monitor (I don't want this), even if I check laptop's as primary monitor.
2) if I try to manually change +1920 in -1920 (samsung's position), then I can't save my changes (GIU don't let me do this).

What can I do?

I'm not an Nvidia user (technically I am however I use nouveau), but does Nvidia use an internal RandR extension? I'd think the better and maybe easier way to do this would be with xrandr if possible.

ngoonee · 2010-09-19 22:46:51

nvidia is still using xrandr 1.1. Configuration should be done with nvidia-settings if possible. TwinViewXineramaInfoOrder is the one which determines which is the primary screen.

You might also want to check out disper. It's a utility to manage heads connected to nVidia cards. It's in the AUR.

zero-giulio · 2010-09-20 07:42:31

nvidia-settings doesn't work well for me.
I need to try something else.

I'll try disper (this is the first time I hear about this program).

And, what's about xrandr. Where can I found guide about dual monitor configuration using it?

Thanks

ngoonee · 2010-09-20 08:42:15

Google, please. Questions that sound like "what is X, what does it do?" have almost no place on the Arch forums.

jdarnold · 2010-09-24 15:39:42

What do you mean "nvidia-settings does't work well for me"? One trick is to make sure you run it as root, esp. via sudo.

Arch Linux
