Hi @mmaurus and thanks for your query. Linux support is available for certain eye tracking models such as the Tobii 4C for which an early alpha is already released, however, I am afraid that for the time being the XR SDK on which the Vive EyeTracker is based is Windows only.
If however, you have any other Tobii eye trackers, please let us know and we can try and find the best solution for your needs. Best Wishes.
