硬件应该有能力。这个问题可能会涉及硬件、配置和多媒体，但我觉得它最适合这里，如果不是，我很抱歉。我的机器是 Gigabyte BRIX S (GB-BKi3HA-7100)，安装了 F4 版本的 bios。Ubuntu 安装在 SSD 上（全新安装 17.04）。
我下载了一些测试视频，1080 的视频播放有点不流畅，4k 几乎根本无法播放。我知道这台机器的 Kaby-lake 处理器播放 10 位 HEVC 视频应该没有问题，但如果它能播放 1fps 就很幸运了。另一台规格几乎相同的 NUC 没有问题。
我尝试将计算机连接到显示器和电视，结果是一样的。驱动程序对话框显示专有驱动程序正在使用中。我可以正常使用显示器，并且在移动窗口或运行 glxgears 时没有任何伪影或不连贯。除了我注意到的撕裂/不连贯之外，Youtube 似乎播放正常。
我试过 mpv media player、VLC、Gnome Mplayer……它们都产生了类似的结果。请注意，我在 Firefox 中也遇到了这个问题

答案1
您似乎正在使用开源 Mesa 驱动程序，根据Mesa GL 扩展/限制图表尚未正式支持 Kabylake，因此这可能是您当前的问题。您可以等待 Linux 进一步支持，也可以使用 Windows。
