Steps
Confirm the session type first, e.g. echo $XDG_SESSION_TYPE — xdotool and wmctrl are built for X11
Note that xdotool relies on core X11 client operations plus the XTest extension for synthetic input and window queries/moves
Note that wmctrl relies on X11 window-manager hints (EWMH properties) to list, move, and activate windows, none of which exist on the Wayland protocol
Understand that Wayland deliberately omits a global cross-client mechanism for querying other windows or injecting synthetic input, as a security boundary between clients
If the target app runs under XWayland, xdotool/wmctrl may partially work against it but still cannot see or control native Wayland clients
For native Wayland automation, plan to use tools built on Wayland-appropriate mechanisms rather than trying to patch xdotool/wmctrl
Known gotchas
Behavior is compositor-dependent: some compositors expose partial protocols that no generic tool covers uniformly — there is no single Wayland equivalent of X11's global model
Even under XWayland, some window operations that worked in pure X11 may behave inconsistently since XWayland only proxies a subset of behavior
This is a protocol-level restriction rather than a bug to patch around — treat failure on Wayland as expected
