GPU - Specify which GPU should take priority
GPU-intensive applications should be rendered on the more powerful discrete card.
The command xrandr –setprovideroffloadsink provider sink can be used to make a render offload provider send its output to the sink provider (the provider which has a display connected).
Change using the name
xrandr --setprovideroffloadsink radeon Intel
Change using the Provider Index
xrandr --setprovideroffloadsink 1 0
Usage
Use your discrete card for the applications who need it the most (for example games, 3D modellers…) by prepending the DRI_PRIME=1 environment variable:
DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
returns
OpenGL renderer string: Gallium 0.4 on AMD TURKS
