interesting, i haven’t heard of lutris before. it looks like it’s a way to distribute custom wine configurations?
from the install script (Lutris - Open Gaming Platform), you can see that it’s doing the same “run from process” trick that this thread pointed out.
so my guess is that connecting directly to your trainer/HRM/cadence/etc probably doesn’t work, but it CAN pair with your companion app. i’m still holding out to be able to pair directly, preferably (for me anyway) over bluetooth.
