bl-hotcorners tweaked

damo · 2020-02-07 22:56:45

I find that the default setup for bl-hotcorners isn't configurable regarding the polling interval for the mouse position, the delay in a corner until it triggers, and the bounce distance for the cursor away from a corner. I prefer a longer interval and a bigger bounce, and previously I edited the python script values manually.

These tweaks add more options to the bl-hotcornersrc config file, which makes personalizing the values easier:

[Hot Corners]
top_left_corner_command = gmrun
top_right_corner_command = 
bottom_left_corner_command = 
bottom_right_corner_command = 
polling_interval = 0.2
corner_delay = 0.2
bounce_distance = 40

Now we just need someone to convert the script to be used by Python 3x!

EDIT: Did it myself (I think!) bl-hotcorners-python3

NB it needs

pip3 install python-xlib

Thanks for this. I also found the delay too long and Mr Google sent me here.
Also thanks to the bunsenlabs distro for making me aware of this script
which I use in Xubuntu.
