Two Nvidia graphic cards

FIG JAM?

Now I have to learn a new abbreviation.

Edit: OK, I looked it up. I'm Good!

The problem remains.... This is my lspci | grep -i vga output

02:00.0 VGA compatible controller: nVidia Corporation GeForce 400 GS (rev a1)
04:05.0 VGA compatible controller: nVidia Corporation NV34 [GeForce FX 5200] (rev a1)

... and this is my xorg.conf ...

It does not matter if I change the driver to nvidia nor vesa.

I appreciate any replies.

You could look through the X log file. Maybe it will give some clues as to why it isn't accepting your config. It is found in the /var/log folder.

I learned of a new command today that will give you a lot of video card info:

xdpyinfo

I don't know if it will help you any, but it's still a neat little command.

Also try xdpyinfo --help for more info.

[j1s]

Hi,

the xdpyinfo can be found here xdpyinfo.txt

and my Xorg.9.log fil goes here Xorg.log

These two files are a lot of info, but I do not have the knowledge to use it...

Need help.

I find however this line.

(EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)

But again, I do not know how to use it...

[waterhead]

I should have caught this earlier.

It looks like you are not using the nVidia driver, but the open source nv driver. You cannot expect to use these nVidia cards fully unless you actually use the nVidia driver.

The nVidia driver is not open source, and therefore not included with most Linux distros. You should be able to install a version of it from the Ubuntu repositories. In the main menu look for something called "Hardware Drivers". It should have your video card(s) listed, and the nVidia driver. Check the box to enable it, and it will download and install it. Make sure that the xorg.config file says nvidia instead of nv.

If you want the latest and greatest nVidia driver, you can download and compile it from nVidia. This is a little more involving, and will have to be done over if you upgrade your kernel.

[j1s]

I've downloaded the new driver from nVidia, and compiled it. (I had to sudo apt-get install build-essentials first. After that it compiled with no warnings or errors.)

Just befor the login-screen appears, the nVidia logo is displayed, in a fragment of a second. I've tried to change the driver from nv to nvidia and even vesa and vga. The two last one resulted in a config program to appear. But it didn't help much.

[waterhead]

After installing the driver from nVidia (which you did), run this command.

sudo nvidia-xconfig

The you can open the display settings console to make adjustments.

sudo nvidia-settings

Do this with root permissions (sudo), because there is the option to save the settings to the xorg.config file. The fact that the nVidia logo is displayed a startup is a good sign.

Hi,

tried these commands after work, today, but sadly, it's the same result.

Only one screen is showing the desktop.

ARGH!!

I'm soon loosing my temper. Luckily I'm going away for the weekend, starting tomorrow. Won't be back until Sunday.

Thanks anyway, Mr. Waterhead.

Those two commands are just to get the nVidia driver set up and working on normal setups. Since you have two cards, a bit more work is needed.

When you ran the nvidia-settings program, did it have both of your cards listed? They will be on the left side, with a name like GPU 0 and GPU 1. Click on it and take a look at the cards info. The BusID is listed differently than the lspci command gives. Use this in your xorg.config file. Also check things like the IRQ, to make sure both cards aren't using the same one.

Also, near the top of the left side, click on "X Server Display Configuration". Here you can configure the displays. Click on one of the displays showing in the window, and the click on the "Configure" button. I think that you want to choose "Separate X Screen".

I never tried to video cards, so I don't know how they would appear in the nvidia-settings program. It seems like you should be able to do it all from there, but tweaking of the xorg.config file may still be necessary.

What you are trying to do is rather uncommon, so patience is needed. I may not have the final solution to this, but at least you are now on the right track. You may want to seek help at a forum that specializes in Linux multimedia PC's, the Linux section of AVS Forums.
