Ubuntu – ATI/Intel hybrid graphics 16.04 LTS


Since I have an onboard Intel graphics card, and a ATI Radeon display controller, I was wondering if I could switch between the two as my graphics in use, as I could in 14.04 LTS through ATI Catalyst?

16.04 LTS is using the onboard, and the hardware listing lists ATI as well as display controler, but not in use. Additional drivers don't provide anything.

So is AMDGPU being used, or is ATI disabled?

To use the AMD Graphics card, execute this command:

DRI_PRIME=1 ./executable

If you want to run a Steam game with AMD Graphics Card, you should set the Game Launch Options on Steam with this command:

DRI_PRIME=1 %command%

To test manually if this is working, you can execute this:

glxinfo | grep "OpenGL renderer"

This command will show your Intel Graphics Card. Execute this command to see your AMD Graphics Card:

DRI_PRIME=1 glxinfo | grep "OpenGL renderer"

For example, in my case, when I execute glxinfo | grep "OpenGL renderer", my output is this: OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile

But, when I execute DRI_PRIME=1 glxinfo | grep "OpenGL renderer", my output is like this: OpenGL renderer string: Gallium 0.4 on AMD CAPE VERDE

There are other commands to test, If you want more tests:

glmark2 (use intel) and DRI_PRIME=1 glmark2 (use AMD)
