Thread: Triple-screen configuration

  1. #1

    Default Triple-screen configuration

    Hi!

    I don't get three screens properly configured on my openSuse11 machine. Sax doesn't seem to support triple screens natively so I used the nVidia configuration utility. I enabled the third monitor and restarted X and then I got an X setup like in the image attached. As you can see, the left screen looks normal, the center one has a checkerboard and the third one is black, but I can still move my cursor to this screen. I can drag my windows on first and second screen, but not on the third one. On the second and third one I cannot open context menu by right-clicking on desktop. Do you have any idead how I can get this running properly? But it must be possible somehow, cause I saw a linux machine with 6 projectors attached once!

    Kind regards,


    Phong

    I don't know the definitive answer on this, but if you 'google' similar topics, you will quickly realise the results depend on the the Xorg config and the desktop environment as well. KDE4, for example, does not yet support multiple desktops yet, but Xfce seems to.

    Maybe post your xorg.conf for a start. Have you tried the xrandr approach? Are you using one multihead nvidia video card? Hopefully, with more info, someone may be able to help you further on this.

    Have a look at this Debian-based howto:

    http://wiki.debian.org/XStrikeForce/HowToRandR12

    It will give you an insight and still be relevant.

    I agree with the previous poster, more info will be needed to properly assist you with this. I recently got a similar setup working, and I can tell you what I did.

    My setup involves two video cards. The primary card (GeForce 8800GT) drives the center (primary) monitor, while the secondary card (GeForce 8400GS) drives the left and right monitors.

    I started the configuration by using sax2 to get one functional monitor (you don't need to bother getting the others set up here) so that I could get into KDE and access the nvidia-settings utility. I then used the nvidia-settings utility to adjust the rest of the settings. I did have to manually adjust some settings to make x recognize my primary card as the primary card. It came up as the secondary by default.

    One thing to note is that for KDE, you will need to enable Xinerama. I did not have this enabled initially, which left me with the black screens with the visible cursor as you are getting on your third monitor. In Gnome, the setup worked fine without Xinerama, with each monitor having a separate x session.

    I'll post my xorg.conf for you to look over and compare to yours. If you give us some more details, we will be better able to help you troubleshoot.

    Default Re: Triple-screen configuration

    Hi!

    Thanks a lot for your replies!
    With your approach I managed to get my desktop on all 3 screens so far, but now my wacom tablet doesn't work correctly anymore. First about my setup:

    I have 2 nvidia GTS250 graphics cards. Left screen and center screen are connected to the primary graphics card while the right one is connected to the second card. I got KDE as my window system.

    Now my wacom works fine one the left screen, but the center and the right one are mapped only about by half. I looked some configuration options up on the wacom linux project manuals and saw, that there are only options for either TwinView or Xinerama. But in this case I got a mixed environment, it's xinerama to get both graphics card merge the screens to one desktop and it's TwinView to get the two screens of the primary graphics card work together. So now I'm pretty confused and lost with the setup and I hope that some of you can help!

    Enclosed is my xorg.conf:

    Default Re: Triple-screen configuration

    Ok, now I got all my screens running AND my wacom is properly mapped. I used the nvidia configuration utility and set up the 2 monitors that are attached to one graphics card as TwinView and the third one as separate X screen.

    But now the there are a lot of graphics und interface issues. The cursor is only visible in the TwinView screens and disappears on the single monitor attached to one graphics card. Also there's no wallpaper anymore. Instead the windows, whenever dragged, are leaving trails. Any idea what I did wrong?

    Code:

    Default Re: Triple-screen configuration

    I am not at all familiar with the Wacom tablet, is there a reason it has 4 InputDevice entries?

    I notice in your "ServerLayout" section that you are missing a screen definition. You have Screen 0 and Screen 1, but not Screen 2.

    Compare yours:
    Code:
    Section "ServerLayout"
        Identifier     "Layout[all]"
        Screen      0  "Screen0" 0 0                  << First Screen
        Screen      1  "Screen1" RightOf "Screen0"    << Second Screen
        InputDevice    "Keyboard[0]" "CoreKeyboard"
        InputDevice    "Mouse[1]" "CorePointer"
        InputDevice    "Mouse[3]" "SendCoreEvents"
        InputDevice    "Mouse[5]" "SendCoreEvents"
        InputDevice    "Mouse[7]" "SendCoreEvents"
        Option         "Clone" "off"
    EndSection
    to mine:
    Code:
    Section "ServerLayout"
        Identifier     "Layout[all]"
        Screen      0  "Screen0" 1280 0               << First Screen
        Screen      1  "Screen1" LeftOf "Screen0"     << Second Screen
        Screen      2  "Screen2" RightOf "Screen0"    << Third Screen
        InputDevice    "Keyboard[0]" "CoreKeyboard"
        InputDevice    "Mouse[1]" "CorePointer"
        Option         "Clone" "off"
        Option         "Xinerama" "on"
    EndSection
    You are also missing the appropriate "Monitor," "Device," and "Screen" sections for the third monitor further down. While you do have 3 entries for each, the entries with the square brackets (Monitor[0], Screen[0], device[0]) around the numbers are the entries placed by sax2, and are disregarded (as far as I can tell) once you use the nvidia-settings utility. At best, they are only duplicates of your primary entries for the respective fields (Monitor0, Screen0, Device0). You will need to add Monitor2, Screen2, and Device2 sections with the appropriate settings for your third monitor.

    Another excerpt from my config for example:
    Code:
    Section "Monitor"                         << Primary Monitor (center)

    Default Re: Triple-screen configuration

    Also, you shouldn't need to use TwinView for anything. Try setting up each screen as a separate x-session with the nvidia-settings utility and make sure xinerama mode is on. I see you resolved the missing Monitor, Device, and Screen sections on your own; but you are still missing the declaration in the "ServerLayout" section.

    Code:
    Section "ServerLayout"
        Identifier     "Layout[all]"
        Screen      0  "Screen0" 1280 0
        Screen      1  "Screen1" LeftOf "Screen0"
        Screen      2  "Screen2" RightOf "Screen0"   << You still need this one
        InputDevice    "Keyboard[0]" "CoreKeyboard"
        InputDevice    "Mouse[1]" "CorePointer"
        Option         "Clone" "off"
        Option         "Xinerama" "on"

    I also recommend you remove the legacy sax2 entries. It may not make a difference system-wise ( I don't really know ), but it makes your xorg.conf easier to read. If you aren't sure which I'm talking about, they are the following sections:

    Default Re: Triple-screen configuration

    Cool, I followed your instructions and the three screens work pretty well now, except that the most left screen, which is connected among the right screen to the secondary graphics card, doesn't have a wallpaper and no GUI context-menu. But I can drag the windows on there. Is this nvidia issue or X configuration issue?

    Code:
    # nvidia-settings: X configuration file generated by nvidia-settings
    # nvidia-settings:  version 1.0  (buildmeister@builder62)  Wed May 27 01:59:40 PDT 2009

    Default Re: Triple-screen configuration

    That sounds a bit odd that you would be able to drag windows there but not be able to do anything else... Could you get a screenshot and post it? You probably have KSnapshot installed, that works for taking a screenshot. I don't see anything in your xorg.conf that looks like it would be the cause of the issue... What version of the Nvidia drivers are you using?
