This looks promising, thank you!
EDIT: This is the way! I was able to use gdctl to change my monitor setup. I couldn't find any tutorials online aside from the example at the bottom of the man page. Once I configure everything to my liking (including pactl) I'll do a write up and edit my post. Thank you!
How do you send the ctrl key? My mobile keyboard doesn't have ctrl, alt, shift, or super modifiers.
