Sleep and wakeup HDMI

Hi folks,

I am using IMX8MP Verdin development board(5.4.161 BSP) with HDMI display.

In verdin development board Native and DSI-HDMI adapter available. How to sleep native HDMI, I have also referred below link.

echo off > /sys/class/drm/card1-HDMI-A-1/status
echo on > /sys/class/drm/card1-HDMI-A-1/status

Using this command I think HDMI is enable/disable. Can you please clear more on this and how to sleep HDMI?

Hi @kishan ,

Yes, these two commands is to enable/display HDMI output.
For sleep mode, you need to use weston.ini. More info refer here

Hi @sahil.tx,

using weston.ini i have configure idle-time.

but application is running on display and weston is going to sleep when idle-time is reached.

can you please suggest how to resolve this?


how to reset idle-time ?

Hi @kishan ,

Please clarify, do you want your application also to sleep when idle timeout is reached for the display?

Hi @sahil.tx,

Currently When an application is running still Weston is going to sleep. So, How to prevent Weston does not go into sleep mode while the application running on display.


can we reset idle-time form the client application?

Hi @kishan ,

Which OS you are using on your Verdin iMX8MP (Linux /Torizon?)
Basically you need to edit weston.ini file using file operation and reload weston services

hi @sahil.tx,

I am using Linux for Verdin iMX8MP.

Hi @kishan ,
Editing weston.ini file and reloading should do the needful
