The parameter “–dsfrd” allows you to set a delay time for the Touch Controller to become active, in milliseconds (ms), after a device wake-up from a sleep state.
This is useful because monitors take a little time to warm up and present their usual EMI levels. We need to delay the Touch Controller wake-up time to allow for the monitor(s) to reach its usual EMI noise levels.
To see the current Delay value:
$ displaxservice -a 127.0.0.1 --dsfrd
To set the Delay to 3000 ms (3 seconds, for example):
$ displaxservice -a 127.0.0.1 --dsfrd 3000
