Ever wish you could literally draw on your screen in Ubuntu Linux?

Well, there’s a new GNOME Shell extension that lets you do exactly that: draw on the Linux desktop.

Why is this useful? Well, you may want to point out a bug, highlight a feature, or provide some guidance to someone else by sending them an annotated screenshot.

And for those things this novel new add-on is up to the job.

Draw on the Linux Desktop

While not all of us have need to graffiti our screens by drawing on the desktop, and on those occasions you do you probably use a screenshot annotation tool like Shutter or take a screenshot and open it in The GIMP.

But the suitably titled “Draw on Your Screen” extension for GNOME Shell adds to those options.

The ‘Draw on Your Screen’ extension offers a simple, straight-forward way to point at, call-out, circle, annotate or draw attention to something on your desktop or computer screen.

There aren’t many write on screen apps available for Linux, especially not ones that are as easy to use as this.

It speeds up the ‘annotate screenshot’ process which usually involves taking a screenshot, opening it in an image editor like The GIMP, marking it up, saving, and then sharing it.

Available tools include:

  • Shapes (rectangle, circle, etc)
  • Lines (including variable thickness)
  • Free-hand drawing
  • Text (any font family, size, etc)
  • Choice of colours

The add-on supports undo/redo, offers a smooth stroke option, persistence (so you can keep adding to your screen-based masterpiece) and support for multi-monitor set-ups.
