I remember recently using a Linux app, applet, or extension that allowed the user to define actions for each corner of the screen (monitor). It was very simple to use, and had options for each screen corner including minimise (minimize), maximise (maximize), and close window. Simply moving the cursor to a corner of the screen would perform the desired action (no clicking required). The user could define a different action for each corner of the display.

It was similar to Linux Mint's Hot Corners app, but included the pre-defined functions mentioned above.

I thought it was available via Linux Mint's Extensions app (whose data is reflected on https://cinnamon-spices.linuxmint.com/extensions), but I'm not seeing it there. Another possibility is that it was available or included with Elementary OS.

Can anyone recommend such a tool for Linux Mint? It must be gratis and open-source.

With Linux Mint's Hot Corners you can use Run a command (It's in the hot corners menu). All you have to do is install xdotool.

xdotool lets you programatically (or manually) simulate keyboard input and mouse activity, move and resize windows, etc.

sudo apt install xdotool

man xdotool

Tested with Linux Mint 21.3 Cinnamon

minimize ; You can try this command :

xdotool getactivewindow windowminimize

maximize

xdotool key --clearmodifiers Alt+F10

close

xdotool key --clearmodifiers Alt+F4

  • Thanks so much. That works great most of the time. For some odd reason, windows will now occasionally get larger than the screen, or not maximize to the full size of the screen. Any idea how to resolve that?

  • Given that you are experienced with xdotool, do you know why running the following command does not work to minimize an open Bluefish Editor window? xdotool search --name 'bluefish' windowminimize

  • This works for me with bluefish: xdotool search --name 'bluefish' windowminimize %@ (%@ = current window, not necessarily with focus). I'll check for maximize.

  • That works from the terminal. Thank you! Why is the %@ needed? Also, do you why doesn't it work when added as a command in the Startup Applications app?

  • I've updated the command to maximize. Not sure why the %@ is sometimes needed with search. What command do you use at startup? I think you have to start bluefish first.
