First time visitor (with an account) and posting. I have installed Ubuntu Desktop 20.04 LTS on a very low cost, Intel based, mini pc, for the purpose of doing some IoT management, running a few low use apps. Headless config, deployed a "dummy" HDMI connector, no keyboard/mouse. Use either ssh or remotePC to connect into. All is working well for my needs, except for the suspend issue.

I do not want this device to suspend - ever. I have set all settings I can find for the System UI (under power), but when as far as installing/using dconf editor to up values to long times (years) and other settings to never, etc.

This seemed to work, however, only when I am logged in as a user. If I logout, the device still suspends at ~ 20mins. My workaround is to log in, lock screen, be done, but I want to resolve this as I may have someone remove/replace power some day. I don't want them to have a need to login, lock, etc.

Any ideas, pointers to other sites/docs on how to resolve this, i.e. under any circumstance, device should never suspend/hibernate -- my choice.

thanks in advance!

Answer in this link:

Prevent sleep/suspend when not logged in to a specific account

Ran this command for both AC and battery:

sudo -u gdm dbus-launch gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'nothing'

sudo -u gdm dbus-launch gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery-type 'nothing'

Rebooted, Ubuntu has been up now for a couple of hours. I would expect to see the problem in ~20 mins.
