Delay After Sleep

Delay After Sleep

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:

  1. 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
