SleepTimer

A simple python (and QT) app to sleep, hibernate, reboot or shutdown a system after a set period of time.

I made this to compliment a refurbished Surface Pro (hence simple UI) that I had recently purchased. All of the apps I found either didn't work, weren't optimized for touch, or ran on Electron. (Granted, the libraries for this will be quite large also, but I use Python anyway.)

Should work on Windows and Linux.

Features

• Set a timer between 1-180 minutes
• When the time is up, the application will pause playing media
• You can select Restart, Shutdown, Sleep or Hibernate.
• [Optional] Audio volume to reduces over the last minute
• [Optional] Change the brightness of the screen

Note
Brightness setting will only work on Windows and Xorg on Linux. It's also possble to turn the backlight off using this setting, so I added a button to enable it to be safe. You have been warned.

Requirements

Windows

Install Python: https://www.python.org/downloads/windows/

pip install PyQt5 screen_brightness_control keyboard

Linux

Ensure Python is intalled via your package manager

Install xdotool from your distributions package manager

pip install PyQt5 screen_brightness_control

Useage

python main.py [--lodpi]

HiDPI

The script will use HiDPI by default. If you wish to use the standard setting, pass --lodpi as an argument.

TODO

• Pause playing audio when going to sleep
• Slowly adjust volume down (maybe in the last minute or two?)
• Possibly add brightness control
• Make the dial and spinbox react to the time decreasing.
• Make the UI more uniform on both platforms.
• Okay I need to fix the UI on windows, it's pretty awful (see screenshot)
