We’ve installed 5.0.2 on a NX platform and performed minimization steps (mainly removing desktop) as described here: Step 1: Removing GUI - Guide to Minimizing Jetson Disk Usage
# sudo apt remove ubuntu-desktop* firefox ubuntu-docs libreoffice-* xorg* # sudo apt autoremove
When using the standard jetpack, the system doesn’t poweroff on its own.
But, with the minimized graphics display it does so after 20 minutes of inactivity, roughly.
We observed, that the minimized version contains different power settings, that tells it to hibernate/go-to-sleep after 20 minutes of idle time.
However, changing that value to never doesn’t completely solve the problem.
As it’s relying somehow on screen activity as well.
Only after we change screen settings to never poweroff, the system runs without interruption.
The kern.log shows exactly the sequence of voltage regulation before powering off.
My questions are:
- What settings can affect such behavior?
- How can we change them through command line, assuming now graphics interface exists?
- Is it possible for future releases to set the settings the other way so that by default it remains powered? As minimization is meant for headless operations.
