I have a desktop that has Elementary installed. I often use the desktop remotely, over SSH through local LAN or with Tailscale, but I am often disconnected from my session when using SSH. I found this SE answer about it disables suspending and sleeping completely.

Is there a way to disable suspend/sleep when using SSH?

  • I don't know anything about Tailscale. Does it offer you the chance to add a command to your login?

  • You should configure SSH on the server. More info here tinyurl.com/grbjqnb

  • I'm considering removing the Tailscale ref as it is not helpful. Tailscale is built on Wireguard but has a nice wrapper. I am trying to prevent suspend/sleep when I am connected remotely via SSH (no matter how I retrieved the IP)

You can use something like systemd-inhibit to block sleep/suspend while you're running the command. This has the express benefit of being a dynamic solution, rather than masking the calls entirely.

Eg: systemd-inhibit --what=sleep --mode=block ssh

I use this to stop my machines from shutting down while my backups are running. Once the command completes, it stops blocking sleep.
