Hotcorners for the poor

A minimal script to launch actions depending on the mouse position (corners). Works for me in XFCE4 (4.20)
Code: Select all
#!/bin/bash
# nohup hotcorners >/dev/null 2>&1 &
# xdotool based script to fire up different actions
# M. Eerie @ forum.porteus.org
# 8-Feb-2025
read screen_width screen_height < <(xrandr --current | awk '/\*/ {split($1, res, "x"); print res[1], res[2]}') # Get screen dimensions
threshold=10 # Define corners threshold in pixels. Adjust as necessary
while true; do
eval $(xdotool getmouselocation --shell) # Get mouse position
# Check corners / Do actions
if [ $X -le $threshold ] && [ $Y -le $threshold ]; then
xdotool key super+space && sleep 1 # Combo to show hud ### TOP LEFT CORNER
elif [ $X -ge $((screen_width - threshold)) ] && [ $Y -le $threshold ]; then ### TOP RIGHT CORNER
xdotool exec xfce4-terminal --drop-down && sleep 1 # "Guake" terminal
elif [ $X -le $threshold ] && [ $Y -ge $((screen_height - threshold)) ]; then ### BOTTOM LEFT CORNER
xdotool key super+l && sleep 1 # Lock Screen
elif [ $X -ge $((screen_width - threshold)) ] && [ $Y -ge $((screen_height - threshold)) ]; then ### BOTTOM RIGHT CORNER
xdotool key super+d && sleep 1 # Show Desktop
fi
sleep 0.2 # Wait for it
done

nice, i didn't know xdotool, but you know that also xfce4-terminal works as a drop-down terminal?

In fact, this is what I'm doing
xdotool is fine because it allows you to fire up actions based on your defined shortcuts or your exec command:

Hi M. Eerie,
what exactly does this script do?
What parameter do I have to specify, etc.
For me, this script is cryptic, completely incomprehensible

Hi roro.
This script, named "hotcorners", is designed to trigger different actions based on the position of the mouse pointer on the screen. It relies on xdotool (needs to be present) to perform these actions.
It calculates the screen dimensions and defines a threshold in pixels to detect when the mouse is in a corner.
Then, it has predefined these actions:
- Top Left Corner: Triggers the super+space key combination. (In my system, I have this combo key associated to a script to show a dashboard of applications)
- Top Right Corner: If the mouse is in the top right corner, it opens the XFCE4 terminal in dropdown mode, similar to the "Guake" terminal.
- Bottom Left Corner: If the mouse is in the bottom left corner, it performs the super+l key combination (in my system it locks the screen).
- Bottom Right Corner: If the mouse is in the bottom right corner, it shows the desktop with the super+d key combination that is present in XFCE4.
You can, of course, modify these actions/keys to suit up your needs
