Just wondering since I know a lot of people quietly use a screen-area-select -> tesseract OCR -> clipboard shortcut.

  • I separate subjects of interest into different Firefox windows, in different workspaces – so I have an extension title them and a startup script parse text to ask the compositor to put them in the correct workspace (lets me restart more conveniently).
  • I have automatically-set different-orientation wallpapers for using my 2-in-1 depending on whether I use it in portrait or landscape (kind of just for looks, but I don’t think if anyone else adds a wallpaper change to their screen rotation keybind).

    I’ve got a RPI running a full-screen ‘kiosk’ view from homeassitant that turns an external display on/off based on a motion sensor.

    So basically it’s showing current temperatures, thermostat control, etc. but I have the display turn off after X minutes of no movement and turn on when there has been movement so it’s only on when you’re in the room.

      I’d love to see your implementation specs, code, pr any other technical details you’d like to share. I’m setting up home assistant and one of the things I want it to do is replace the functions of my thermostat and add some additional details.

      I used to have a Nest Thermostat, but my furnace needed to be replaced a couple of months back and I got a Mitsubishi heat pump, but their thermostat sucks, and it isnt compatible with Nest because it’s all wireless. I installed the WiFi add-on to the furnace so I can use the app, too, but it also sucks pretty bad. Plus I miss the functionality of it turning down the heat when I’m away to save money and turning it back on before I get home.

      So I’m planning to implement my own solution and documenting and open sourcing everything. But it’s going to be several months before I get to doing it due to other more urgent projects. So, I’m looking at everything available. I definitely will be setting up a small display to replace the thermostat and having motion detectors to turn on the display when you approach it to see the temperature and such and to supplement the home/away detection.

      Anyway, I would love to see your implementation to see how you did this piece of it.

        It’s really quite simple - but works pretty well. There are 3 components:

        Kiosk service

        A simple systemd service that starts a kiosk script.

        [Unit]
Description=Kiosk
Wants=graphical.target
After=graphical.target

[Service]
Environment=DISPLAY=:0.0
Environment=XAUTHORITY=/home/pi/.Xauthority
Type=simple
ExecStart=/bin/bash /home/pi/kiosk.sh
Restart=on-abort
User=pi
Group=pi

[Install]
WantedBy=graphical.target

        Kiosk script

        The script in /home/pi/kiosk.sh just starts a web browser in full-screen mode pointed at my home assistant instance:

        #!/bin/bash

xset s noblank
xset s off
xset -dpms

export DISPLAY=:0.0 

echo 0 > /sys/class/backlight/rpi_backlight/bl_power

LANDING_PAGE="https://homeassistant.example.com/"

unclutter -idle 0.5 -root &

/usr/bin/chromium-browser --noerrdialogs --disable-infobars --kiosk $LANDING_PAGE

        Display service

        I have a very simple python/flask service that runs and exposes an endpoint that lets you turn on/off the display. It’s called by a homeassistant automation for when the motion detector senses or hasn’t sensed movement.

        Here’s the python - I have this started from another “kiosk.service” systemd service as well.

        #!/usr/bin/env python3
import subprocess

from flask import Flask
from flask_restful import Api, Resource

def turn_off_display():
    with(open(backlight_dev, 'w')) as dev:
        dev.write("1")


def turn_on_display():
    with(open(backlight_dev, 'w')) as dev:
        dev.write("0")


class DisplayController(Resource):
    def get(self, state):
        if state == 'off':
            turn_off_display()
        elif state == 'on':
            turn_on_display()
        else:
            return {'message': f'Unknown state {state} - should be off/on'}, 500
        return {"message": "Success"}


def init():
    turn_on_display()


if __name__ == "__main__":
    init()
    app = Flask(__name__)
    api = Api(app)
    api.add_resource(DisplayController, '/display/<string:state>')
    app.run(debug=False, host='0.0.0.0', port=3000)

        You can then have the HA rest action call this with “http://pidisplay:3000/display/on” or off.

    I use compose key sequences to save time writing out long email addresses. For example, I have something like this in my ~/.XCompose:

    <Multi_key> <b> <o> <s> <at>: "myangryboss@company.com" # Email of my very angry boss

    So I can just type Compose (right alt on my system), bos@ and get his email address. Less error prone than typing out emails manually.

    I’m probably not the only one to use compose strings as a replacement to a text expander, but I don’t know anyone else who does this.

    I boot on a custom EFI app to control my dualboot (instead of systemd-boot or grub) that asks a service on my proxmox server which OS I’m supposed to boot.

    Overkill, but it allows me to control my dual-boot without a keyboard in my computer (because it’s a Bluetooth keyboard so I can’t really use it in grub anyway)
