正如我在这里读到的ATI/Intel 混合显卡 16.04 LTS我可以使用 glxinfo 和 glmark2 测试我的 amd 卡,但这输出的是我的英特尔卡
glxinfo | grep "OpenGL renderer"
> OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile
DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
> OpenGL renderer string: Mesa DRI Intel(R) Ivybridge Mobile
DRI_PRIME=1 glmark2
=======================================================
glmark2 2014.03+git20150611.fa71af2d
=======================================================
OpenGL Information
GL_VENDOR: Intel Open Source Technology Center
GL_RENDERER: Mesa DRI Intel(R) Ivybridge Mobile
GL_VERSION: 3.0 Mesa 12.0.6
=======================================================
但是 lspci 输出说我有 amd 卡
lspci | grep Display
> 01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Mars [Radeon HD 8670A/8670M/8750M] (rev ff)
lspci | grep VGA
> 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
我应该怎么做才能让我的 AMD 卡正常工作,当我运行类似DRI_PRIME=1 blender
