I recently moved to Lubuntu 18.04.3 "Bionic Beaver" and found that alt + PrtSc will screen grab the active window. On Mint and Ubuntu, this key combination lets you manually select which part of the screen to capture, similar to the Snipping Tool on Windows.

How can I enable this functionality on my machine? It saves a lot of time having to crop images in GIMP.

  • Please mention the version of Lubuntu. The output of cat /var/log/installer/media-info will tell you that.

I have Lubuntu 19.10. The default tool is screengrab. Running screengrab --help shows the available options:

  -h, --help        Displays this help.
  -v, --version     Displays version information.
  -f, --fullscreen  Take a fullscreen screenshot
  -a, --active      Take a screenshot of the active window
  -r, --region      Take a screenshot of a selection of the screen
  -m, --minimized   Run the application with a hidden main window

Instead of opening a terminal and running something like sleep 5 && screengrab -r which will launch screengrab after 5s to allow you to minimize the terminal window and view the region you're interested, it is worth making a keyboard shortcut for the purpose.

To make this shortcut, click on Lubuntu's Menu icon (usually located at the left end of your panel) and then open Preferences > LXQt settings > Shortcut keys. I've chosen Ctrl+Meta+I (where Meta is the Windows or Super key and I is for interactive.

Once you save the shortcut, if you press Ctrl+Meta+I, you'll see this which is self-explanatory:

    Perfect! After some fiddling, I set up scrot -s as my alt+PrtSc shortcut! Dec 25, 2019 at 18:20
