Night mode/light option is not available in Ubuntu 18.04 LTS (Jetpack 4 (L4T 31.0.1))


How can I set or control display temperature (like reading mode/night light) to 3500K in order reduce burden on my eyes?

For example on my desktop/PC ubunutu 18.04 LTS, I have option to enable night light under display menu as shown below.

But, this night light option is not available in Jetpack 4 (L4T 31.0.1) ubuntu 18.04 version.

please let me know, if there is any workaround to accomplish this setting?

Note: though my external monitor, which is connected to Jetson dev board, does support reading mode, but is not sufficient for me.

Sorry for the late response, have you managed to get setting successfully?

no, this issue is not yet resolved.
