Ubuntu 16.04 VA-API 与 iGPU / ESXI 直通的问题

我有一个运行 Ubuntu 16.04 客户端的 ESXi 盒。它是 i5-5300U（因此所有技术都可以启用 Intel GPU PCI 直通）。

我安装了 vainfo + i965-va-driver 及其所有依赖项，但vainfo失败了：

error: can't connect to X server!
libva info: VA-API version 0.39.4
libva info: va_getDriverName() returns -1
libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)
vaInitialize failed with error code -1 (unknown libva error),exit

如果我强制使用LIBVA_DRIVER_NAME=i965 vainfo或DRI_PRIME=1 vainfo：

error: can't connect to X server!
libva info: VA-API version 0.39.4
libva info: va_getDriverName() returns -1
libva info: User requested driver 'i965'
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_39
vainfo: intel_driver.c:106: intel_driver_init: Assertion `VA_CHECK_DRM_AUTH_TYPE(ctx, VA_DRM_AUTH_DRI1) || VA_CHECK_DRM_AUTH_TYPE(ctx, VA_DRM_AUTH_DRI2) || VA_CHECK_DRM_AUTH_TYPE(ctx, VA_DRM_AUTH_CUSTOM)' failed.
Aborted (core dumped)

我已经束手无策了，因为它与同一系统上的一些驱动程序（英特尔更新工具、第三方 PPA 等）一起工作，结果是：

error: XDG_RUNTIME_DIR not set in the environment.
error: can't connect to X server!
libva info: VA-API version 0.39.2
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_39
libva info: va_openDriver() returns 0
vainfo: VA-API version: 0.39 (libva 1.7.3)
vainfo: Driver version: Intel i965 driver for Intel(R) Broadwell - 1.7.1
vainfo: Supported profile and entrypoints
      VAProfileMPEG2Simple            : VAEntrypointVLD
      VAProfileMPEG2Simple            : VAEntrypointEncSlice
      VAProfileMPEG2Main              : VAEntrypointVLD
      VAProfileMPEG2Main              : VAEntrypointEncSlice
(...)

然后我重新启动，就再也没有看到这个成功了。

您将如何解决该问题？

也许我的解决方案对其他人有用：

sudo chgrp video /dev/dri -R
sudo chmod 666 /dev/dri/*
sudo chmod 755 /dev/dri

瞧！
