无责任给个类似问题的链接：https://bbs.archlinux.org/viewtopic.php?id=175164
你尝试看看是不是权限问题。另外Xorg.log也看看是否提示加载哪个驱动，尝试看
看指定驱动

glxinfo的吧。
某的：
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile
OpenGL core profile version string: 3.3 (Core Profile) Mesa 11.0.6
OpenGL core profile shading language version string: 3.30

顺带提一下某用的是Gentoo Linux，内核版本4.4.8-r1 hardened，
Mesa版本11.0.6，x11-drivers/xf86-video-intel版本2.99.917_p20160423

这样，某觉得比较快的可以下载一个SystemRescueCD跑起来看看是否正常，
以及尝试安装其他发行版，比如Ubuntu最新的桌面版，ArchLinux等。
另外请问下你这个板子的具体型号。

[ 7.856264] i915 0000:00:02.0: No connectors reported connected with modes
[ 7.856278] [drm] Cannot find any crtc or sizes - going 1024x768
没找到任何显示器，Xorg intel driver应该也fail了，看一下Xorg.0.log，
所以fallback到soft render了. 试试新的kernel吧，最近好像fix了一个类似的
connector detect问题.
p.s, 和vmware驱动没啥关系，因为mesa那帮人被vmware买了，所以gallium的
vendor改成vmware了，呵呵

设个fake output，glx可以用mesa/i965 driver
或者干脆不要X，直接用mesa EGL on drm也可以，EGL+GL/GLES，但可能要改程序code

我想我大概找到原因了。
今天给 ThinkPad X220 Tablet 装了 Debian，glxinfo | grep "OpenGL vendor string" 依旧是 VMWare, Inc.
突然有种感觉，怀疑是跟 ssh 有关系。之前 minnow board 就没插显示器，导致 Intel 驱动不加载，可能需要fake output一下(?)
于是直接扒拉开本子直接用了 ThinkPad 的屏幕，glxinfo 了一下，vendor string: Intel Open Source Technology Center
我的猜测：
glxinfo 会受 X11 Forwarding 的影响？实际上会用 client OGL driver？
除了 transcoding 还想要 offload gfx 啊，这就必须要驱动或者 Open Source Media Kernel Runtime 了毕竟没有显示器，不能让显卡闲着浪费

Transcoding都不用起X, 直接用libva intel driver就行了，或者闭源的media sdk...
