英特尔卡上没有GLX，带有额外的nVidia卡
我有多个配置，我的Xorg有2个服务器布局。 一个用于nVidia卡，另一个用于Intel卡。 它们都工作，但分配给Intel卡的显示服务器没有硬件加速，因为正在使用的DRI和GLX模块来自nVidia驱动程序。
所以我的问题是，我能否以某种方式配置布局，以便在每张卡上使用正确的DRI和GLX？

好的，所以找到了一个解决方案，但是在Ubuntu 12.10中使用新的Mesa 9.0.1库存在阻止硬件加速在Intel GPU上工作的错误 。
简而言之，问题在于加载GLX。 nVidia将推出自己的GLX模块并踩上英特尔的脚趾。
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/usr/lib/x86_64-linux-gnu/xorg/extra-modules中/usr/lib/x86_64-linux-gnu/xorg/extra-modules都是特定于nVidia /usr/lib/x86_64-linux-gnu/xorg/extra-modules 。 所以我配置LightDM使用两个xorg.conf文件。 在Intel one中，我手动设置ModulePath不包括nVidia目录。 这导致加载适当的GLX模块。
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
添加到xorg.conf.intel ：
Section "Files" ModulePath "/usr/lib/xorg/extra-modules" ModulePath "/usr/lib/xorg/modules" EndSection
在我看来，使用Ubuntu 14.04，路径是不同的，Nvidia专有驱动程序覆盖/usr/lib/xorg/modules/extensions/libglx.so libglx.so 。
要解决这个问题，我复制/usr/lib/xorg/modules /usr/lib/xorg/modules-nvidia中的/usr/lib/xorg/modules-nvidia ，然后重新安装Intel友好的libglx.so ：
sudo apt-get install --reinstall xserver-xorg-core
这将恢复原始的libglx.so 。 在xorg.conf.nvidia ，我添加了有效模块的路径：
Section "Files" ModulePath "/usr/lib/xorg/modules-nvidia" EndSection
另外，在/etc/lightdm/lightdm.conf我必须在[Seat:1]部分添加： xserver-command=/usr/bin/X -sharevts 。 在这里找到了这个提示。
非常感谢MeanEYE以正确的方式指出了我。
所以我做了一些研究，发现有许多不同的方法可以实现Multiseat（多站，多终端等）配置。
1）我建议的方法，因为它使用你的标准Xorg和内置的内核驱动程序，使用evdev 。 以下是如何使用evdev设置4 GPU和4监视器多节点配置的指南。 该指南适用于Debian Sarge和SiS GPU，但我认为您可以从本指南中推断出许多非常有用的信息： https ： //en.wikibooks.org/wiki/Multiterminal_with_evdev
2）另一种方法是使用Xypher ，一种基于KDrive的不同X Windows服务器。 我不确定这是你想要去的路线，但不管怎么说这是指南： 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，该工具承诺为您自动化整个设置过程，但是，它似乎没有更新，所以我不推荐它。 不过，您可以轻松地将Google作为最后手段使用。
我不知道你对你的配置做了什么或者没有做过什么，所以最好的办法是阅读evdev指南并尝试确定你尚未完成的步骤。 我看到的最大的不同是
A）在示例xorg.conf中，只有1个Screen和ServerLayout部分。 附加的Screens和ServerLayout在一个单独的conf中定义：xorg.conf.probe
B）此外，所有设备都由其BusID明确引用，这些ID是使用lspci和
C） irq 10禁用中断。
希望这有助于您的运行，祝您好运！
在Ubuntu 16.04中，我需要更新/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变量并设置export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/mesa:/usr/lib/i386-linux-gnu/mesa/ only for英特尔卡。
在18.04，glvnd支持允许用户非常容易地安装Mesa和专有的Nvidia驱动程序 ，而不必弄乱LD_PRELOAD！ 现在不需要所有环境变量和包装脚本。
由于这没有使用特定的Ubuntu版本标记，并且现有的答案不能完全适用于我的系统（Ubuntu 15.10），因此我发布了使用logind答案。
基本上，要使GLX和libGL工作，您必须配置X服务器和用户会话以使用正确的libGL实现，具体取决于座位。
因此，您需要LightDM的包装器脚本来启动X，并使用Xsession脚本来设置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 $DISPLAY" | grep -q seat0; then export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/mesa:/usr/lib/i386-linux-gnu/mesa/ fi
（假设seat1使用nvidia和seat0台面）
类似地，你需要包装X服务器（ /usr/local/bin/X ）：
#!/bin/bash if grep -q seat1 <<<$*; 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，您需要配置LightDM以在/etc/lightdm/lightdm.conf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 repo ，其中包含更多详细信息并具有完整的配置文件和脚本。
我正在使用Arch linux，但这对我的英特尔和我的Nvidia专有驱动程序加载gl/vaapi/vdpaufunctiongl/vaapi/vdpau 。
所有你需要做的（q＆d）：
安装专有的nvidia-utils 。
将/usr/lib/xorg/modules复制到/usr/lib/xorg/modules_nvidia
下载并解压缩最新的libva-intel-driver ， mesa-vdpau ， mesa ， mesa-libgl和xorg-server作为适合您的体系结构的软件包放在一个单独的目录中。 然后cp -r （作为root / sudo）将"separate directory"/usr/lib改为/usr/lib_intel和"separate directory"/usr/lib/xorg/modules/*到你的实际/usr/lib/xorg/modules目录（覆盖）。
和
echo "/usr/lib_intel" > /etc/ld.conf.d/intel_glx.conf ldconfig
重启X-Servers ，试试glxinfo
当然，这会在nvidia-updates上自毁。
我发现重启时这不起作用。
更好的黑客：
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;$PREV_LD_LIBRARY_PATH export LD_PRELOAD=/usr/lib_intel/libGL.so fi
将“vt7”更改为显示管理器用于启动intel x-server的任何内容（：0，：2，vt7，vt8，isolatodevice = …）
当然，你也可以将/ usr / bin / X复制到/ usr / bin / Xintel并编辑它，将你的wm指向这个文件（kdm’ServerCmd’）。
然后，编辑或创建一个新的会话文件，即/ usr / bin / startkde（不检查DISPLAY＃！），添加：
export LD_LIBRARY_PATH=/usr/lib_intel;$PREV_LD_LIBRARY_PATH export LD_PRELOAD=/usr/lib_intel/libGL.so
这样，你甚至不需要覆盖任何东西。 rm’ing / usr / lib_intel目录并重置2个已编辑的文件是您需要再次删除此hack所需的一切。
