带有附加nVidia卡的多座Intel卡上没有GLX

我已经配置了多人座，并且我的Xorg有2个服务器布局。一种用于nVidia卡，另一种用于Intel卡。它们都可以工作，但是分配给Intel卡的显示服务器没有硬件加速，因为所使用的DRI和GLX模块来自nVidia驱动程序。

所以我的问题是，我可以配置布局以对每张卡使用正确的DRI和GLX吗？

我的Xorg.conf：

Section "ServerLayout"

    Option         "Xinerama" "0"

好的，因此找到了一个解决方案，但是存在一个错误，该错误阻止了使用新的Mesa 9.0.1库在Ubuntu 12.10中的硬件加速在Intel GPU上运行。

简而言之，问题是加载GLX。nVidia会推销自己的GLX模块，并加强英特尔的脚步。

我注意到这一行找到了一个解决方案：

[    18.240] (==) ModulePath set to "/usr/lib/x86_64-linux-gnu/xorg/extra-modules,/usr/lib/xorg/extra-modules,/usr/lib/xorg/modules"

即，位于其中的模块/usr/lib/x86_64-linux-gnu/xorg/extra-modules都是nVidia特定的模块。因此，我将LightDM配置为使用两个xorg.conf文件。在Intel one中，我手动设置了ModulePathnVidia目录。这导致了适当的GLX模块的加载。

我的/etc/lightdm/lightdm.conf文件如下所示：

[SeatDefaults]
user-session=ubuntu
greeter-session=unity-greeter
allow-guest=false

[Seat:0]
xserver-layout=Default
xserver-config=xorg.conf.nvidia

[Seat:1]
xserver-layout=TV
xserver-config=xorg.conf.intel

行添加到xorg.conf.intel：

Section "Files"
    ModulePath     "/usr/lib/xorg/extra-modules"
    ModulePath     "/usr/lib/xorg/modules"
EndSection

在我这一边，使用Ubuntu 14.04时，路径是不同的，并且Nvidia专有驱动程序libglx.so在中被覆盖/usr/lib/xorg/modules/extensions/libglx.so。

为了解决这个问题，我复制/usr/lib/xorg/modules的/usr/lib/xorg/modules-nvidia ，然后重新安装英特尔友好libglx.so与：

sudo apt-get install --reinstall xserver-xorg-core

这样就恢复了原来的状态libglx.so。在上xorg.conf.nvidia，我将路径添加到有效模块：

Section "Files" ModulePath "/usr/lib/xorg/modules-nvidia" EndSection

另外，/etc/lightdm/lightdm.conf我必须xserver-command=/usr/bin/X -sharevts在[Seat:1]部分添加：。在这里找到了这个技巧。

非常感谢MeanEYE，他以正确的方式指出了我。

因此，我进行了一些研究，发现可以采用多种不同的方法来实现Multiseat（多工作站，多终端等）配置。

1）我建议的方法是使用evdev，因为它使用标准的Xorg和内置的内核驱动程序。这是有关如何使用evdev设置4 GPU和4显示器多座配置的指南。该指南适用于Debian Sarge和SiS GPU，但是我认为您可以从该指南中推断出很多非常有用的信息：https : //en.wikibooks.org/wiki/Multiterminal_with_evdev

2）另一种方法是使用Xypher，这是基于KDrive的另一台X Windows服务器。我不确定这是您要走的路线，但是无论如何，这里都是该指南：https ://en.wikibooks.org/wiki/en: Multiterminal_with_Xephyr

3）另一个选择是使用一个名为Multiseat Display Manager（MDM）的工具，该工具可以为您自动完成整个设置过程，但是，它似乎没有更新，因此不建议使用。不过，您可以通过Google轻松找到它。

我不知道您对配置已经完成或尚未完成，所以最好的选择是阅读evdev指南并尝试确定尚未完成的步骤。我看到的最大区别是

A）在示例xorg.conf中，只有1个Screen and ServerLayout部分。附加的Screens和ServerLayout在单独的conf中一起定义：xorg.conf.probe

B）此外，所有设备均由其BusID明确引用，这些BusID是使用lspci和

C）在irq 10上禁止中断。

希望这可以帮助您启动并运行，祝您好运！

在Ubuntu 16.04中，我需要使用以下命令更新/usr/local/bin/X包装器：

exec /usr/bin/Xorg -modulepath '/usr/lib/xorg/extra-modules,/usr/lib/xorg/modules' "$@"

/etc/X11/Xsession.d/00ldlibrary可以测试$XDG_SEAT变量并 export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/mesa:/usr/lib/i386-linux-gnu/mesa/仅针对Intel卡进行设置。

在18.04中，glvnd支持使用户可以非常轻松地安装Mesa和专有的Nvidia驱动程序，而不必担心 LD_PRELOAD！现在不需要所有环境变量和包装器脚本。

由于未使用特定的Ubuntu版本标记该标签，并且现有答案无法在我的系统（Ubuntu 15.10）上完全正常工作，因此我将发布使用的答案logind。

基本上，要使GLX和libGL工作，必须根据位置将X服务器和用户会话都配置为使用正确的libGL实现。

因此，您需要一个用于LightDM的包装脚本来启动X，并需要设置一个Xsession脚本，LD_LIBRARY_PATH以便会话使用正确的libGL。

在/etc/X11/Xsession.d/00ldlibrary：

#!/bin/bash

if ps aux | grep "/usr/local/bin/X $DISPLAY" | grep -q seat1; then
    export LD_LIBRARY_PATH=/usr/lib/nvidia-352:/usr/lib32/nvidia-352
fi
if ps aux | grep "/usr/local/bin/X $DISPLAY" | grep -q seat0; then
    export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/mesa:/usr/lib/i386-linux-gnu/mesa/
fi

（假设seat1使用nvidia和seat0 mesa）

同样，您需要包装X服务器（/usr/local/bin/X）：

#!/bin/bash

if grep -q seat1 <<<$*; then
    export LD_LIBRARY_PATH=/usr/lib/nvidia-352
    echo "Detected seat1, using nvidia-352 libs"
fi
if grep -q seat0 <<<$*; then
    export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/mesa
    echo "Detected seat0, using mesa libs"
fi

exec /usr/bin/Xorg "$@"

最后，您需要将LightDM配置为在/etc/lightdm/lightdm.conf以下位置使用它们：

[Seat:*]
# needed to use the correct libraries for mesa/nvidia,
# along with a Xsession.d script (00ldlibrary)
xserver-command=/usr/local/bin/X
session-setup-script=/etc/X11/Xsession.d/00ldlibrary

有关更多详细信息，请参阅我的multiseat-mesa-nvidia存储库，其中包含更多详细信息以及完整的配置文件和脚本。

我正在使用Arch linux，但这对我和Intel和Nvidia专有驱动程序都加载了一些gl/vaapi/vdpau功能。

您需要做的所有事情（q＆d）：

安装专有的nvidia-utils。

复制/usr/lib/xorg/modules到/usr/lib/xorg/modules_nvidia

下载并解压缩最新的libva-intel-driver，mesa-vdpau，mesa，mesa-libgl，并xorg-server为封装在一个单独的目录适合您的架构。然后cp -r（以root / sudo身份）将内容复制"separate directory"/usr/lib到类似的目录/usr/lib_intel并复制"separate directory"/usr/lib/xorg/modules/*到您的实际/usr/lib/xorg/modules目录中（覆盖）。

和

echo "/usr/lib_intel" > /etc/ld.conf.d/intel_glx.conf
ldconfig

重新启动X-Servers，尝试glxinfo

当然，这会在nvidia更新上自毁。

我发现重新启动时不起作用。

更好的技巧：

不要创建ld.so.conf.d /文件。而是将以下内容添加到/ usr / bin / X：

PREV_LD_LIBRARY_PATH=$LD_LIBRARY_PATH
if [[ "$@" == *"vt7"* ]]
then
export LD_LIBRARY_PATH=/usr/lib_intel;$PREV_LD_LIBRARY_PATH
export LD_PRELOAD=/usr/lib_intel/libGL.so
fi

将“ vt7”更改为显示管理器用来启动英特尔x服务器的任何内容（：0，：2，vt7，vt8，isolatodevice = ...）

当然，您也可以将/ usr / bin / X复制到/ usr / bin / Xintel并进行编辑，将wm指向该文件（kdm'ServerCmd'）。

然后，编辑或创建一个新的会话文件，即/ usr / bin / startkde（不检查DISPLAY＃！），添加：

export LD_LIBRARY_PATH=/usr/lib_intel;$PREV_LD_LIBRARY_PATH
export LD_PRELOAD=/usr/lib_intel/libGL.so

这样，您甚至都不需要覆盖任何内容。删除/ hack / lib_intel目录并重置2个已编辑的文件是您再次要删除此hack所需要做的一切。
