Hi Juanito
... I take it you mean to update hsetroot and not to add hsr-outputs?
There aren't many descriptions of its purpose to be found. There is this:
hsr-outputs - command line tool to list screen sizes and positions
Found here:
https://github.com/himdel/hsetrootLooking at the source code, it uses an Xinerama call to get a list of X offset, Y offset, width, and height for every
screen found. It has the option to print the results as text, csv, or json.
