【问题描述】：
我有一个具有以下硬件的专用服务器：
CPU: Intel(R) Xeon(R) E-2386G CPU @ 3.50GHz
Motherboard: Manufacturer: ASRockRack, Product Name: E3C252D4U-2T/OVH
根据 Intel 网站，E-2386G 有 Intel Quick Sync，我想用它。 我试图检查系统中有哪个 VGA（预计会看到 Intel + 本地），这是输出：
05:00.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 41)
即，Intel iGPU 在系统中根本无法识别，我尝试检查/dev/dri 那里的现有设备是什么，这是输出：
ls -alh /dev/dri
total 0
drwxr-xr-x 3 root root 80 Sep 19 10:28 .
drwxr-xr-x 18 root root 4.2K Sep 20 13:05 ..
drwxr-xr-x 2 root root 60 Sep 19 10:28 by-path
crw-rw---- 1 root video 226, 0 Sep 19 10:28 card0
当我尝试运行vainfo 工具时，我得到以下结果：
香草运行：
vainfo
error: can\'t connect to X server!
libva info: VA-API version 1.7.0
libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)
vaInitialize failed with error code -1 (unknown libva error),exit
设置export LIBVA_DRIVER_NAME=i965后运行：
vainfo
error: can\'t connect to X server!
libva info: VA-API version 1.7.0
libva info: User environment variable 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_1_6
libva error: /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so init failed
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit
使用 sudo 运行：
sudo vainfo
error: XDG_RUNTIME_DIR not set in the environment.
error: can\'t connect to X server!
libva info: VA-API version 1.7.0
libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)
vaInitialize failed with error code -1 (unknown libva error),exit
如何使用英特尔快速同步？
