Dual GPUs are no issue for x.org it’s just that automatic configuration assumes a somewhat standard machine or it gets confused. Should I tell you about the days before automatic configuration, of hand-editing XF86Config to tell the X server that no, I didn’t have a serial or ps/2 mouse but an USB one, and it had three buttons and a mouse wheel? Of seeing a list of monitor timings with the comment “CHOOSING THE WRONG THING MIGHT DESTROY YOUR HARDWARE”?
xrandr is actually quite recent (or I may be ancient), being able to do all that stuff at runtime was a godsend.
