 +**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.
