Features

Tracking features

• Track your total laptop usage per day in houres, and total daily usage [ track-laptop-usage.sh]
• Give short information to user as soon as lid is open:
  • how long computer was suspended [ power-management.sh]
  • how long computer was hibernated. [ power-management.sh]
• Make a simple chart showing how long computer was used on daily basis. [ track-laptop-usage.sh, show-graph.sh, chart.py ]

Charting

• Plot bar chart of total usage time per day.
• Plot heatmap of laptop usage in hourly precision. -A day is divided in 24 hours, if user spent whole time in this hour without any breaks this hour is counted as 60 (60 whole minutes that user spent in this hour). If for example user had 15 minutes break in given hour it will result in score 45.

Power management features

• Control when user computer will be suspended. [ power-management.sh ]
  • Suspend after X inactivity time
  • Do not suspend if
    • There is music playing on local sound card or Bluetooth speaker
    • Rsync is running
    • Pacman is installing some stuff
• Before going in to suspend mode check if user is sitting at front of computer: [ power-management.sh ]
  1. Make a picture
  2. Check if on picture is a face
  3. If not - suspend.
  4. Last check is stored in suspend_check.jpg file
• Prevent from running script twice [ start_power_management.sh ]

Bugs:

• Once I found computer was not supsending because sound card was giving false information that is "RUNNING", pulseaudio -k, imediattely solved problem.

Installation

On arch/manjaro run:

• bash install.sh if you are on different distro inspect install.sh and install packages specified in this file using your package mangager.

Or if you want just to track time without controlling when your laptop will be suspended, start this script on every fresh start of your system:

• bash start_track_laptop_usage.sh

To show plot you need to run:

• bash show-graph.sh

To start using suspending and hibernation feature you need to start this

• bash start_power_management.sh

Settings

You can set settings in power_management.set for example: bash suspend_time_set=1 # Suspend computer after inactivity [minutes] suspend_on_discharging_set="on" # set to "on" or "off" suspend_on_charging_set="on" #

After changing values restart of script is not needed

Troubleshooting

If you encounter problems you can run directly:

• bash power_management.sh

1. Check if .log files are created in log folder and records created.
2. Check if path to log file in chart.py is correct

TODO:

• Do not suspend computer if there is ongoing installation from pacman.
• Do not suspend computer if there is rsync running.
• Notify user that he exceeded productive daily/weekly limit of hours.
• Simplify installation process to bare minimum.

Summary

Overall this is small nice tool to play with :)
