Multi monitors on two NVIDIAs

#1

Hi.

I want to use three monitors on NVIDIA Quadro2000 and NVIDIA GeForce GTX750 Ti.
I installed hardwares, maybe they work but a monitor on GTX750 Ti not displayed.

$ lspci | grep VGA
0f:00.0 VGA compatible controller: NVIDIA Corporation GF106GL [Quadro 2000] (rev a1)
28:00.0 VGA compatible controller: NVIDIA Corporation GM107 [GeForce GTX 750 Ti] (rev a2)

X couldn’t start when wrote BusID "PCI:0f:00:0" on Device section in /etc/X11/mhwd/nvidia.conf.

It’s not effect that wrote /etc/X11/mhwd/nvidia.conf using Bare Mosaic with nvidia-settings, and sudo mhwd-gpu --setgl nvidia --setxorg /etc/X11/mhwd.d/nvidia.conf.

I think they are enabled because ffmpeg encoding fps is higher than Quadro 2000 only.

Monitor on GTX750Ti is shown in nvidia-settings but disabled.
Options are “Disabled”, “New X screen” or “Enable Base Mosaic”.

How to display to three monitors on Quadro 2000 and GeForce GTX 750 Ti?

Thanks in advance.

Maybe you can use base mosaic mode for it? https://wiki.archlinux.org/index.php/NVIDIA#Mosaic_mode

Thank you for your reply.

I understood Base Mosaic is currently solution,
but nvidia-settins enabled Base Mosaic but it didn’t work thus error:

BusID is set “PCI:15:0:0”. This log differs from lspci.

BusID “0f:00:0” or “28:00:0” didn’t start X.

nvidia-settings creates this configuration.

It not work if overwrote metamodes like “GPU-0.DFP-0”.


#5

Manjaro is not using the default /etc/X11/Xorg.conf, but /etc/X11/mhwd.d/nvidia.conf. So you need to let nvidia-xconfig know where to put in the file. So the command should be something like this:

Of course, change the GPUx, DFP-x, and resolution to match your configuration. Good luck :slight_smile:


#6

Thank you.

I tried

sudo nvidia-xconfig --xconfig=/etc/X11/mhwd.d/nvidia.conf --base-mosaic --metamodes="GPU-0.DFP-0: 1920x1080+0+0, GPU-0.DFP-1: 1920x1080+1920+0, GPU-1.DFP-1: 1920x1080+3840+0"

but I got same result GPU PCI IDs do not match.

Like I mentioned above, modify GPU-x, DFP-x to match your system configuration. You can look at my screenshot here to understand what you need to do :slight_smile:


#8

Yes, I understood it.

every monitors FHD(1920x1080) and they are put horizontal, so I think

--metamodes="GPU-0.DFP-0: 1920x1080+0+0, GPU-0.DFP-1: 1920x1080+1920+0, GPU-1.DFP-1: 1920x1080+3840+0"

is right setting (match with screenshot.)

I think EE on log says error is in device section rather than screen.

Maybe this problem likely

#9

Maybe, did you try making it into 2 screens? So X Screen 0 for your 750ti and X Screen 1 for your Q2000?


#10

No, I didn’t.

If don’t use Base Mosaic, Quadro2000 uses Screen 0, and GTX750Ti able to use new screen or disable.
but if enable Base Mosaic, GTX750Ti able to select disabled or join Screen 0.

If configurate GTX750Ti use Screen 1, X didn’t start.


#11

You already have 3 monitors shown there. Are you using 4 monitors? Because as far as I know, Nvidia base mosaic only supports maximum 3 monitors. Read the Note here: https://wiki.archlinux.org/index.php/NVIDIA#Base_Mosaic


#12

No.

Third monitor on GPU.1(GTX750Ti) not displayed because Base Mosaic wasn’t enabled with error.

nvidia-settings shows third monitor (22EN43) as disabled.


#13

But your screenshot before showing all 3 monitors on? I just Googled and found out that your PCI ID should match in order to use base mosaic (that means you need two identical cards/SLI). So you might want to try separate Screens or twinview instead of base mosaic.


#14

It’s modified on nvidia-settings window…
Third monitor was disabled on start nvidia-settings.

I tried to delete line about BusID and Base Mosaic, and turn on MultiGPU.
It errored GPU PCI IDs do not match same as Base Mosaic, so cannot enable two NVIDIA cards by any other technology (e.g. multi screen.)

#15

same issue from me.

i have 2 monitors:
the first monitor is connect to the nvidia display card via displayport.
the 2nd monitor is connect to the first monitor via displayport 1.2 daisy chain / MST.

both monitors are enable / activated in the display settings and nvidia settings. But the screen is only shown in the first screen if I enable both screen.
if I disable the first screen, I can see the 2nd screen.

endup I have the workaround by adding this in .xprofile:
xset dpms force off; sleep 1; xset dps force on


#16

Thank you for your reply.

I added it to .xprofile, but didn’t work.
Two monitors on Quadro2000 were displayed but a monitor on GTX750Ti wasn’t displayed.
RandR didn’t see a monitor on GTX750Ti yet.

#17

Base mosaic is for SLI. I think that’s what causing it. Hope someone with the same configuration with you can help you with this as I don’t have 2 different GPU to test this out. :slight_smile:


#18

Humm… I saw Base Mosaic is non SLI system’s technology, SLI Mosaic is SLI system’s one.
http://nvidia.helpmax.net/en/workstation/mosaic-and-sli-mosaic/reference/mosaic-and-sli-mosaic-mode/

I found descriptions that mosaic technology is supported by only Quadro cards.
Possibility, it is causeing.

But it’s not acceptable.
Xinerama was able to like it, but now not able with nvidia driver.
https://wiki.archlinux.org/index.php/multihead#Xinerama
Is alternative way nothing?

I have one more question.
Suppose it cause GTX750Ti don’t support Base Mosaic, but GTX750Ti should support MultiGPU technology.
But I got same result as Base Mosaic when delete base mosaic configuration and add MultiGPU configuration…


#19

I found not quite solution.

  • Assign each screen to each monitor.
  • Enable Xinerama.

But it’s not cool.

  • Awful performance.
  • Blinking conky widget.
  • Very unstable.

If possible, I want to use Base Mosaic and MultiGPU.


#20

The latest Nvidia 367.35 changelog:

  • Removed the Base Mosaic configuration option from nvidia-settings on systems where the feature is not actually supported.
    And 367.35 is currently in testing repository of Manjaro. You can change your branch to testing by doing sudo pacman-mirrors -g -b testing and do sudo pacman -Syyu.
    Open up nvidia settings and see if you got that option to make sure base mosaic is really possible for your cards first. :slight_smile:
