Thanks, I'll have a look at those areas you suggested. I appreciate you getting back to me about it.

This is because the moment that the input libraries are loaded, a check is done to see which devices are connected; this check is not performed again at a later date. If you wish to support this, I suggest to take a look at linux_input.c and think about how this could be extended; what you want is to add a new entry to the device_names array, and call driver_open_device with the new index. Enabling/Disabling the cursor is done via IDirectFBDisplayLayer::EnableCursor, I believe. hth Niels BJ Opp wrote: > Hey all, has anybody been able to toggle the cursor on/off at > runtime?
