时间:2018-04-03 02:53:24

标签: ubuntu-16.04 nvidia multiple-monitors xorg multi-gpu

目的:

在两个相同的GPU上安装带有监视器的多监视器扩展显示器。

设备:

  • Geforce GTX 970(x2)
  • 戴尔E207WFP显示器(x6)
  • Z97-PRO主板
  • i5-4690K CPU @ 3.50GHz
  • 24GB内存

软件:

  • Ubuntu 16.04.04 LTS
  • 4.4.0-116-generic kernel
  • NVIDIA驱动程序版本384.111

测试程序

1)硬件测试

  • 测试了每个监视器及其端口。 (成功)
  • 使用GPU&amp ;;一次一个地测试每个Mobo PCI端口。监控。 (成功)
  • 测试了每个GPU及其所有显示端口。 (成功)

    注意:每个GPU都有1个显示器,1个HDMI和2个DVI端口。

    • 自行测试每个端口。 (成功)
    • 测试了同时显示的所有端口。 (成功)
  • 单独测试所有布线。 (成功)

2)软件测试

  • 如果Ubuntu可以在扩展模式下处理1个GPU上的4个监视器,则进行测试。 (成功)
    • 显示器1:全屏播放高清电影。
    • 监视器2:游戏方式的生存是在最高质量的设置下发展的。
    • 监控3:Active Discord视频通话。
    • 监视器4:OBS软件渲染游戏&主动流的不和谐。
  • 测试Nvidia X Server是否可以在同时插入时同时看到两个GPU。 (成功)

    注意:默认情况下禁用一个GPU。

尝试我的目标

我尝试了xorg.conf文件的许多配置。 我获得大多数试验的最接近成功的是:

  • 所有屏幕都在工作,显示延长的屏幕保护程序图像 在监视器上。
  • 鼠标可以快乐地穿过所有屏幕 屏幕保护。
  • 不幸的是,当我尝试登录时,我得到了一个 无限登录循环,重新加载登录屏幕并重新提示 再次登录。

澄清

这是无限登录循环问题。 无限登录循环是我问题的症状。

有几个无限循环的问题/答案,那些假设你犯了一个错误并想要修复"重置为默认值的问题。以下是其中一些重置为默认值"修复'这不是我的问题。

想要重置为默认值,并且可以在每次尝试后将我的系统恢复到一个显卡的工作状态。我问如何进一步更改设置/配置以获得我的目标(没有登录循环)?

2 个答案:

答案 0 :(得分:3)

好吧,我通过一些广泛的研究和测试回答了我的问题。如果你有一个多gpu,多监视器系统,你想要一个统一的桌面(这意味着Windows可以捕捉到监视器,并且可以跨监视器拖动程序窗口,无论哪个监视器在哪个gpu上)。然后简短的回答是Nvidia显卡的SLI /基础Mosaic。

但是,除非您花费60多个小时阅读文档并与他人交谈(这就是我所做的),否则会丢失多个信息点。

我将提供多个链接和澄清点,以帮助其他人的挫折和努力。了解所有命令和建议来自Ubuntu 16.04,Unity DE,Nvidia Geforce驱动程序v380 +立场,可能不适用于其他系统和硬件。

Nvidia - > X服务器& RandR

以下几点[错误]沟通:

  • RandR (本机安装的显示管理器,也在CLI中称为xrandr)
  • X服务器(输入和输出之间的主要管理/连接系统,包括Xorg,xorg.conf方面)
  • Nvidia-settings (Nvidia的显示管理器向X服务器和RandR发送信息)

使用nvidia-settings时,Nvidia将配置并向x服务器和RandR发送错误信息,然后在内部处理逻辑本身。

  1. Nvidia有自己的xinerama与X服务器xinerama分开。如果你在xorg.conf文件中启用xinerama,那就是X服务器自己的Xinerma而不是Nvidia(如果你试图通过nvidia-settings做某事,那就不要这样做了。

  2. Nvidia会将所有显示器置于1个屏幕下,并将此屏幕作为统一桌面呈现给X服务器,同时使用自己的内部xinerama逻辑让RandR正确查看单独的显示器。

    • 这意味着在xorg.conf中制作单独的屏幕,监视器和设备部分正在打破nvidia-settings管理桌面的自然方式(I.E.禁用Nvidia的内部xinerama)。这将需要在xorg.conf文件中启用X服务器的xinerama(但是这会破坏我在开始时提到的统一桌面期望之一)。
    • 即使在处理多个gpus渲染桌面时,它仍然作为1个屏幕呈现给X服务器,同时使用其内部逻辑向RandR报告所有可用的监视器。这将需要一个名为base / SLI Mosaic的选项,但我也需要在下面澄清。
  3. Nvidia的结束 - > RandR& X服务器说明

    Nvidia - > xorg.conf

    Nvidia如何使用xorg.conf文件并不反映您在X serverX orgxorg.conf文档中所读到的内容。相反,您需要专注于阅读Nvidia文档。但是,当您转到文档时请注意URL。 ' / README /'之前的数字需要是你的Nvidia驱动程序版本号,这是' 390.42'在下面的示例网址中。很多谷歌点击nvidia设置文档对旧驱动程序来说真的是老文档。如果您获得旧文档,这将引导您完成循环。 示例:

    http://us.download.nvidia.com/XFree86/Linux-x86_64/390.42/README/index.html

    1. 如前所述,Nvidia只向X服务器报告一个屏幕。在这里,我将向您展示xorg.conf文件的Section "Screen"示例,以便澄清。
    2. Section "Screen"
          Identifier     "Screen0"
          Device         "Device0"
          Monitor        "Monitor0"

          Option         "metamodes" "GPU-0.DFP-0: nvidia-auto-select +0+0,

      • 正如您可以看到它仍然是一个屏幕,但metamode可以是特定的 使用哪个gpu和端口。
      • 另一点是,MultiGPU并不是指主板上显卡的数量。
      • nvidia-auto-select负责您的Horizo​​n同步,垂直刷新范围,显示器分辨率,但正如您可以从用于显示器放置的尾随数字中看到的那样,我希望它将我的系统分辨率设置为1680×1050。

      不太模糊的Section Screen是:

      Section "Screen"
          Identifier "Screen0"
          Device "Device0"
          Monitor "Monitor0"
          DefaultDepth 24
          Option "Stereo" "0"
          Option "nvidiaXineramaInfoOrder" "DFP-0"
          Option "metamodes" "GPU-a0bd4a65-1c2b-f765-eeb2-db96b3f4b25a.GPU-0.DVI-I-1: nvidia-auto-select +0+0,

      • 通过添加GPU哈希,您可以直接说明要使用哪些图形卡,而不是将其留给系统进行解释。
      • DVI-D-0在我的系统上==到DFP-4,所以没有任何解释留给系统,但我认为使用端口类型而不是DFP广告管理系统展示位置会消除歧义用户。

      Nvidia的结束 - >的xorg.conf

      SLI / Base Mosiac catch 22

      所以最终的答案是SLI使用nvidia-settings作为我想要的统一桌面时需要Mosiac。但是,如果不是Quadro或NVS 选定的GPU系列,则只能在两个或更多GPU上启用允许三个屏幕。这并不是因为我宝贵的Geforce GTX 970的技术无法处理它,因为Nvidia在nvidia-settings代码中人为地限制了它以推广他们的新GPU。我可以从这个Nvidia forum以及查看测试存储库中的source代码中注意到这一点。

      事实上,最初你可以在2个未选择的GPU上拥有3个以上的屏幕,直到296个驱动程序强制进行更改。

      如果你在没有合适的GPU的情况下仍然尝试,它将导致所有屏幕都显示在RandR GUI和Nvidia设置GUI中。但是,您会注意到除三个监视器外的所有监视器都将被禁用,并且只有在禁用已启用的3个监视器中的一个时才能启用它们。

      有用的命令

      xrandr --listproviders

答案 1 :(得分:1)

我最近有机会做一些非常相似的事情:2个Nvida GPU, 每个驾驶3个显示器。我在过程中发现的一些东西 让它工作是:

  1. 如果您从单个GPU驱动多个显示器,您将会 需要为每个头和每个设备部分设置一个设备部分 需要一个'屏幕编号'选项,其中'编号'从0变为1 少于连接的监视器数量。

  2. 我认为每台显示器需要一个屏幕部分。来自 xorg.conf手册页:'A“屏幕”代表图形的绑定 设备(设备部分)和监视器(监视器部分)。'

  3. ServerLayout中Screen选项中的screen-num参数 section与屏幕中的屏幕编号参数无关 “设备”部分中的选项。

  4. 调试X windows配置时我发现有用的东西 问题是以多用户模式启动系统(将“3”附加到 在早期启动屏幕中的内核参数),创建一个简单的.xinitrc 文件(比如,只有'xterm'行(假设你有xterm) 安装)),然后用'startx'启动X.然后,如果(何时)它 失败,您将能够查看/var/log/Xorg.0.log中的日志文件, 对xorg.conf进行更改,然后重试。

    我对你的xorg.conf文件进行了一些编辑。我评论了一些选项 在屏幕部分,因为它们将取决于您的本地端口 名称,你肯定想要改变屏幕的方式 安排在ServerLayout部分。

    我希望您可以将此作为获得工作设置的基础。它的 很烦人,因为一切都必须适合它的工作 所有
