Steps
Install ydotool and confirm the /dev/uinput kernel module is available, since ydotool creates a virtual input device via the Linux uinput framework rather than talking to a display-server protocol
Start the ydotoold background daemon, which is required and owns the persistent virtual device while listening on a socket
Set up permissions: add a udev rule granting input-group access to /dev/uinput, and ensure the ydotoold socket is accessible to the calling user
Run ydotool client commands (key/mouse actions) against the running daemon rather than expecting it to work standalone
Set up a systemd user service for ydotoold if it needs to persist across sessions
Known gotchas
ydotool works on both X11 and Wayland because it bypasses the display server entirely at the kernel level, but this means it has no concept of specific windows — it cannot target, move, resize, or focus a particular window the way xdotool/wmctrl can
Without correct udev/group permissions or a running ydotoold, commands fail with permission-denied errors — a common first-run stumbling block
Because input arrives as if from a real keyboard/mouse, it goes to whatever currently has focus, with no per-window targeting to compensate
