## Device State - Active and Inactive
To solve this problem, each device can be in exactly two states:
Events can only be sent to active clients.
Events can only be received from inactive clients.
Either events are sent or received.
Active denotes that a particular device is controlled by the local pc.
This ensures that
- a) Events can never result in a feedback loop.
- b) As soon as a virtual input enters another client, lan-mouse will stop receiving events,
which ensures clients can only be controlled directly and not indirectly through other clients.
Any event received from an active device is ignored unless it is a state change request.
In this case the device is marked as inactive and no further events are sent to the device.
The received events are then processed until a further state change to active
is requested (when the corresponding layer surface is entered).
**In short:** The invariance "each client either sends or receives events" must
always be true.
