I have a new instal of Leap42.1 x86-64. I am running it under LXDE. Using the nvidia G03 drivers. It is a dual head card. There are two in my system that are both valid (works in a windoze dual boot). I should be able to run 4 monitors. At this point only one card, using two monitors is working. Does anyone know how to get the other to work? I have tried xrandr and it tries to configure it, shows the third monitor in the window, but on apply, crashes. Here is the output from that.

I have also tried the nvidia tools. That also recognizes that it is there, but doesn’t set it up.
It shows GPU 0 -(Quadro NVS 290) with DFP-0 & DFP-1, and also GPU 1 - (Quadro NVS 290) with DFP-1
In the X Server Display Configuration the third monitor shows as (Disabled)
When I select to configure as option - new X screen and apply it states “the current settings cannot be completely applied due to …” then a list of possible reasons.
option s are apply what is possible or cancel.
Cannot Apply
The current setting cannot be completely applied due to one or more of the following reasons:
- The location of an X screen has changed.
- The location type of an X screen has changed.
- The color depth of an X screen has changed.
- An X screen has been added or removed.
- Xinerama is being enabled/disabled.
For all the requested settings to take effect, you must save the configuration to the X config file and restart the X server.
Apply What is Possible or Cancel
Thanks for the help. Any thoughts?
I select Apply What is Possible. The third monitor is still black. As I look at the X config file it creates, it looks like it is not dual heading either video card. Each should be driving two monitors. Perhaps Xinerama is not working?
When I close out and then come back into the nvidia settings tool, the xconfig is back to the first one.
The message from the settings tool said “For all the requested settings to take effect, you must save the configuration to the X config file and restart the X server.”
Does that mean simply copying the second config file into /etc/X11 as xorg.conf ?
I don’t want to brick this, so am asking first.
nvidia-settings
Package xorg-server was not found in the pkg-config search path.
Perhaps you should add the directory containing `xorg-server.pc'
to the PKG_CONFIG_PATH environment variable
No package 'xorg-server' found

I saved the file to xorg.conf. Anything else before I restart?
OK, we are closer. I now have 3 monitors working. The strange part is the new monitor seems to be a new X window. The cursor changes from the arrow to an X. I cannot move any windows into that screen. If I open a window in that screen it does not show in the desktop pager.
I think we are close. The changes are needed in these sections, but I am not sure what yet. I think it has to do with the DVI or DFP and Xinterama statements. Just need a bit more help. thanks.
Are you seeing all the monitors in nvidia-settings?. I’m wondering if EDID is not working for one or more of the monitors. VGA connector maybe? In any case you can add them manually to the xorg.conf file. then you should be able to setting hings up in the KDE configure desktop screen settings section.
Its not a new X window, its a second Screen … you’re running one X server Display (Display :0) and within that you have configured two Screens (Screen 0 and Screen 1), in which you populate them with your monitors (two in Screen 0 and one in Screen 1 apparently) … so there is nothing strange about that.
you have nvidia’s Xinerama turned off (set to 0) so you are not going to get a contiguous desktop
The cursor changes from the arrow to an X.
because no window manager is running on that second Screen.
I cannot move any windows into that screen.
that’s correct. you cannot move windows across protocol Screens
If I open a window in that screen it does not show in the desktop pager.
that’s because the desktop pager represents the desktop that is being run across Screen0 … the activity in Screen 1 is onto itself
I have no experience with the nvidia metamodes stuff, so you will have to figure that out … or dispense with that and do it a more elementary approach
Or maybe you could get it to work with xrandr setproviders
Yes I agree with the post of Tyler_K
One possibility is to try to set the two graphics cards to act as screen 0.
I am not sure if it will work with just enabling the base mosaic in
the nvidia-settings.
Interesting turn of events here. I did what the nvidia-settings error said, saved the file it created and saved it into /etc/X11/xorg.conf. I now have all three monitors working and usable. Which is great. The strange part is a minor thing, but the back ground is only running across the first two monitors. It is likely because of the Screen0 and Screen1 settings. Below is the xorg.conf that is currently running.
LOL , well that idea didn’t work. Hahaha. The second version, it locked up the Xserver. I will try the first one later. If anyone knows better please let me know.
And to clarify. All three monitors are working, running on two dual-head video cards. I am now in the fine tuning mode if I can. If none of that works, I still have a viable, working system. Below is the xorg.conf that is currently running.
And thanks to all. This is a great community forum. Though openSuse is my primary for years, I have played with other distos a few times, and have to say that by far, this is the most active and helpful forum of any I have been on. Thanks again.
