My problem is that taking a screenshot of a notification breaks the PrintScreen button.

Steps to reproduce:

  1. Trigger one of those pop up notifications that appear at the top of the screen, e.g. by disconnecting from a Thunderbird server, browser notifications, etc.
  2. Hover the mouse on top of the notification and press Alt+PrintScreen, which normally captures a window.
  3. Nothing happens, and the PrintScreen button should now be unresponsive.

I am able to consistently reproduce this on my machine (Ubuntu 18.04.5 LTS). The only way of fixing the button I could find is rebooting.

Is this a known bug? Is there a way to "reset" the PrintScreen button if it becomes unresponsive?

  • Try the following - sudo tail -f /var/log/syslog , keep the terminal open, then take your screenshot using the alt+prtsc and see what populates in the terminal. If you don't understand the output edit your question and post it. tail -f will show the results of the keypress in as soon as you do it. –  Sep 01 '21 at 17:13
  • @TBr nothing was recorded on the terminal. I kept the terminal up and ran the command in the following ways: (a) normally taking an Alt+PrintScreen: nothing logged; (b) taking an Alt+PrintScreen after focussing on the notification (which disables the PrintScreen button); (c) trying to take a screenshot after triggering the PrintScreen bug. In case it was stuck on something, I left the terminal running but nothing was recorded even after waiting (besides unrelated network logs). – laifs Sep 01 '21 at 18:36

I couldn't find a bug report about this issue in Launchpad, so you can file a new bug report against the gnome-screenshot package to let developers know about it. Read this question to know how to file a bug report: How do I report a bug?

When PrintScreen becomes unresponsive, restarting GNOME Shell will probably restore its functionality. To restart GNOME Shell press Alt+F2, type r, and hit Enter.
