nvidia cards
 
Greetings


I have a machine with 2 monitors and 2 Nvidia Grafics cards of Quadro FX 5600 and the driver version is Nvidia 190.42.


My redhat version is RHEL 4.7

When i login to the mahcine it logs me as two different users ,i cannot drag windows from one monitor to the other.


Can any please help me in making the two Grafics card to act as one Grafic card.



Regards

You are using xorg multi-head by default. You need to edit the xorg.conf file so it works differently. There are a lot of threads on this sort of thing, like this one. It features ATI cards but the approach is going to be the same as it does not involve driver specific tricks.

Your differences will ba that the driver is nvidia, and your busIDs will be different - you get them off lspci.

Do you have nvidias own nvidia X server settings software??

I use Ubuntu, and I had problems. But with nvidias software installed, it works ok.

Start nvidia x server settings. Go to the second menu choice at the top: X server display configuration.

Make sure the other monitor is plugged in and on. Click detect displays. The second monitor will appear. It always appears to the right of your monitor. I click the position box and go to absolute, then drag the new monitor over the other one. Then I have two showing the same thing. I've never got it to work as a separate screen, but I only need it to display to class, so that is enough.

I installed Nvidia driver version

when i run the command nvidia-settings i see two screens but i want them to be act as twin view.
Now they are acting as two different desktops.i cannot move the windows between the two monnitors.

Please advise.

alunduil 12-08-2009 02:20 AM

As Pedroski mentioned use nvidia-settings to configure your screens the way you like. It will give you the option to write out the xorg.conf file as well. Easiest way to configure nVidia screens the way you like.

As i mentioned earlier i have two Nvidia cards and two monitors i want both the monitors to be acted as one i.e TWIN VIEW.

in Nvidia-settings command the option for twin view is disabled.


PLease advise how to enable the twinview option.

Pedroski 12-08-2009 03:35 AM

Yeah, disabled is default: go to the button configure, you should get a little window, with three choices: disable, separate screen and twinview. Click the check button, close, then click apply. X restarts, and you should have two screens working. It goes funny if you don't put one on top of the other. Position Absolute, then drag it on top of screen 0, your ordinary screen.
You have 15 seconds to accept, or it reverts!
What do you mean you have two cards?? You only need one!

Pedroski 12-08-2009 03:39 AM

If you leave the new screen at the right, you effectively have a desktop equal to the width of say, mine is 800 plus the other one 768, which is wierd! But then you can drag things off of your screen 0 onto screen 1. A big ol' desktop!

i tried all but the option for twin view is disabled ...i cannot check ...

Please find the attachments....

Pedroski 12-08-2009 04:15 AM

click on screen two, the one on the right, so that it is active. (Has a highlighted frame around it, like the one on the left in your fotos. It must be highlighted to interact with it!
You should then be able to activate twinview.
Works for me!

Pedroski 12-08-2009 04:20 AM

screen 0 is active at boot, but screen 1 needs to be activated, at least for me. I think it should start of its own accord on boot. Save the X config ( there is a button near the bottom) You may need to be root to do that. I just start up nvidia settings when I want it, and set it up, as the screens I use vary!

Set the resolution to Auto, if you don't know the res of your screens. If they are the same, no problem, but if they aren't you will lose bits of the larger in the smaller!

Its disabled.......PLease check the attachment.

Pedroski 12-08-2009 04:30 AM

Wierd, but not unusual for Linux! Have you tried booting with the screen plugged in?
Or run nvidia-settings as root? It took me ages to get things working. I know how you feel!

I would guess you are having root problems! Do it as root!

Pedroski 12-08-2009 04:31 AM

you have two identical screens? Maybe the computer is confused!? Try a different second screen!
