Overview
The Delay After Sleep parameter defines how long the Touch Controller waits before becoming active after the system or display wakes up from a sleep or standby state:
--dsfrd
The delay is specified in milliseconds (ms).
This feature is useful because displays and monitors require a short warm-up period after waking. During this time, electromagnetic interference (EMI) levels may be unstable. Delaying the Touch Controller activation allows the monitor(s) to stabilize, helping prevent false touches, ghost inputs, or inaccurate detection immediately after wake-up.
When to Use Delay After Sleep
Use this setting only if required, if you experience:
-
False or ghost touches after sleep or standby
-
Unstable touch behavior immediately after display wake-up
-
Multi-monitor setups where displays wake at different times
-
High-EMI environments or large displays
Check the Current Delay Value
To view the currently configured wake-up delay:
displaxservice -a 127.0.0.1 --dsfrd
Set the Delay After Sleep
To set a custom delay value (example: 3000 ms / 3 seconds):
displaxservice -a 127.0.0.1 --dsfrd 3000
Notes:
- Set only if necessary
Values are entered in milliseconds
-
Typical values range between 1000 ms and 5000 ms, depending on monitor behavior
Adjust incrementally if further stabilization is required
