Hmm…sorry for the possibly dumb questions on my part, but is your second monitor being picked up still? (Like is it possible that it might not be sending windows to a leftward/rightward monitor because it doesn’t see one there?) And are they in the expected order? (Possibly it can’t send leftward because it thinks it’s already on the left-most?)
If the second monitor is being picked up fine, are those keyboard shortcuts also not working when you boot from a Fedora 37 USB?
