sailfish_background_stop

This script monitors sailfish compositor and sends SIGSTOP and SIGCONT to the command executed through it.

Motivation

• Mosh can handle loss of connection, and even freezing the process between activations.
• Remote terminal applications rarely benefit from being active while the screen is not visible.
• Keeping the connection up in low connectivity places eat battery very fast.
• Disconnecting and reconnecting to check for activity is annoying.

I wanted a solution that I can keep the mosh connected to screen running in a shell server all the time, and not worry about battery being emptied in the morning.

Results

Can keep up connection for few days with single charging of the Jolla phone battery.

I consider this a huge boost compared to 100% to 15% in couple of hours forgotten on in basement with neglible cellphone coverage.

Requirements:

• dbus-monitor
• sed
• bash

And the command you intend to run. Mosh in my case.

Example 1:

Run mosh connection to server in fingerterm (use as command in a .desktop file).

fingerterm -e "/path/to/bgr_stop.sh mosh -- [email protected] screen -rDU"

Example 2:

To run the same mosh command in already opened fingerterm shell, exec to replace the original shell to get the correct parent pid set.

$ exec /path/to/bgr_stop.sh mosh -- [email protected] screen -rDU
