I have a similar setup, but I use an AMD card. I can choose whether to
use the integrated or dedicated graphics with an environment variable,
so I may call scopes like this: `env DRI_PRIME=1 scopes`. Is there
such a mechanism for NVIDIA? I've heard of a similar thing but I'm not
sure if it's as reliable. I don't think it should always be on for a
more generic program like the scopes compiler, while useful in a game
or anything of the sort.
