Turning gaze mode on without a calibration opened Calibrate only on the off-to-on change, and only if it could open right then. With the headset off, the eye tracker silent, or the panel not built, or with gaze mode already on when the gaze service started, nothing opened and nothing said why: the pointer just stayed a mouse. - The gaze service now checks every second: gaze mode on, no calibration for the tracker in use, eyes seen -> the full calibration opens. One that closes unfinished opens again only after the headset comes off and on, gaze mode off and on, or Calibrate, so it doesn't loop. A start that fails retries every 10 s. - Its status says why gaze mode can't work yet (checks.problem): not calibrated and opening, open, closed unfinished, or can't open and why. - Input Settings shows that under the Gaze pointer switch, along with the gaze service not installed or not running and our tracker missing its frame grabber. - ft-gazectl on notes a missing calibration.
