What to know
If the other computer has no Decky Display, it shows a notification with Get Decky Display.
If it does not work
If the computers cannot find each other, check that Network is on in Settings → Connection on both, or enter the address by hand. Unlock a computer to use it as a screen. Disconnect keeps the card until Connect is pressed on either computer or Decky restarts. Forget removes the link, and linking again needs a new code.
