Ok.

[an at GX60 ~]$ xrandr --setprovideroffloadsink 0x46 0x7e
[an at GX60 ~]$ DRI_PRIME=0 glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Gallium 0.4 on AMD ARUBA (DRM 2.43.0, LLVM 3.7.0)
[an at GX60 ~]$ DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Gallium 0.4 on AMD ARUBA (DRM 2.43.0, LLVM 3.7.0)

But in that case nothing happend at all.

This line does not change anything either.
