Grant,
thank you for the prompt reply. So the API in question indeed requires a special license for some reasons. Could you please advise on an alternative solution? All I’d like to achieve here is to minimize power-on to ready time for my setup. As of now, after powering 4C on I have to redo a screen calibration by running ‘tobii_config’ which though straightforward, is not always guaranteed to be successful and takes time. I reckon the calibration is stored on the device itself and is lost after a power cycle. Is there a way to perform a screen calibration once and apply it permanently? It could entirely be I’m overlooking something obvious here as I’m trying to concentrate on other project priorities and only had time for a quick scan through the Linux API…
