What do you mean by "can't get it to work"? How does it not work?

Dual Head Display wont run using yum repolist; You need to do some settings for it!

What are the setting you have done let us.Then let us know the error you are getting!

Follow this link:

Well,
I have my two screen mirroring each other, where i would like some spanning to occur. Impossible to set them to spanning mode (with Graphic interface). I don't know how to set all this in a terminal.
Tx for the lingk ill have a look.

Post the output of the "xrandr" command.

Ok, i have looked at link. That's exactly what im trying to do. I set things to dual head and to spanning, but i press ok nothing happen. Im staying on the setting window. The only action i can do is exit, and of course, then i keep mirror screens. How can i get spanning to work?

What about the xrandr output?

Hello,
Sorry to be a bit late, i wasn't on my linux.
So xrandr output is:

SZ: Pixels Physical Refresh

1 1152 x 864 ( 376mm x 301mm ) 75

6 720 x 400 ( 376mm x 301mm ) 70

tx hips,

Is that absolutely all of it?

If so, Linux only detects one monitor.

all right then, no wonder why it's not working.
The reason might be simple though;
I tried to plug my sreens like i used to do with windows, meaning i got both screens plug on one vga plug behind the computer. It was working this way with windows. But it was not the same computer. Is it coming from the video card? Behind my computer i have got another plug but i dont think it is a vga. It's a male plug with only 9 connectors getting out. I'm not sure what's the use of this plug. Can I use it to plug another screen? There is another blue female plug much wider than the VGA with 25 holes. What's that?
Anyway tx to linux and you guys im learning a lot about how computers work, which is kind of cool.tx hips for your answers

First, could you post the contents of you /etc/X11/xorg.conf file?

It could also not be there, if so, tell us.

ola amigo,

here it is, the output of /etc/X11/xorg.conf.

I remember trying to modify the configuration of this file with some settings found here and there on the web. After that, I wasn't able to access graphic display after rebooting linux. Fortunately linux was offering me to reset the graphic interface to its original setting.

cheers

Try renaming the xorg.conf file so that X can't find it, and then restart X.

Then try posting te output of xrandr.
