EyeX dies on calibration (Operation timed out)

[Jacob Boyle]

Hello, I’m trying to get up and running with the EyeX – however it is dying during the calibration process.

It manages the first step – where it shows you how it sees your eyes – just fine.

However, on the second step – where it asks you to focus on and follow the little dot – it fails. The lights on the EyeX device go out, and the dot just sits there. Eventually an error popup appears and the config application quits.

I’ve looked at the logs, and this is all I could find:

Hi Jacob,

Sorry to hear about the problems. Since you get the message “No displayDeviceName found for index 1” in the log, I suspect the problem has something to do with that the display is not recognized correctly. For example, we are aware of problems when cloning the desktop on several screens or when there is a desktop-sharing application installed. Can you share more information of how your screens are set up?
