There’s still a bunch of little bugs in KDE6, they’ll get ironed out over time. For the KDE connect bug I use a ydotool command to emulate an enter key press to accept the remote command access from my bed.
The command itself isn’t complex:
YDOTOOL_SOCKET="$HOME/.ydotool_socket" ydotool key 28:1 28:0
The hard part is getting ydotool to run on boot for your user (no sudo). I had to create a bash script to run on login with the following line:
ydotoold --socket-path="$HOME/.ydotool_socket" --socket-own="$(id -u):$(id -g)"
It’s a bit hacky but it works.
