-====== GPU - Specify which GPU should take priority ======
-GPU-intensive applications should be rendered on the more powerful discrete card.
-If more than one GPU is install, you can specify which one should be used.

-===== Usage =====
-Use a specific card for the applications that need it the most, such as games.
-To select the card with Provider 1, prepend **DRI_PRIME=1**:
-<code bash>
-DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
-</code>
-returns
-<code bash>
-OpenGL renderer string: Gallium 0.4 on AMD TURKS
-</code>
-<WRAP info>
-**NOTE:**  Other applications will still use the default first card.
-These settings are also lost once the X server restarts.  You may want to make a script and auto-run it at the startup of your desktop environment (alternatively, put it in /etc/X11/xinit/xinitrc.d/).
-This may reduce your battery life and increase heat though.
