Screenshot when active on a menu

When trying to take a screenshot with gnome-screenshot whilst you are active on some menu, I've found it doesn't tend to work.

Well, a couple of weeks ago I decided to do some research and managed to find a work-around. As you may know, pushing the Print Screen button causes the Ubuntu program gnome-screenshot to fire (which is can be changed to an alternative program if you with wish), resulting in a captured image of your current workspace. As like most software, there are a number of arguments that can be passed – one of which happens to be a delay, where you can specify when gnome-screenshot will fire, with the parameter: –delay=x where x is the number of seconds to wait. By adding this parameter, it gives you enough time between when you push it and when the delay finishes to navigate onto the appropriate menu, so that it can be included in the screenshot.

So, if you fire up gconf-editor, and navigate to:


You will find 2 configuration items associated with screenshots. I decided to edit the command_window_screenshot setting, so as not to mess-up the standard one. This way, whenever I want a screenshot with a menu involved, I just hit the alternative key combination – by default it is Alt+Print Scrn. So, I edited the property so that it reads

gnome-screenshot --window --delay=3

3 seconds tends to give me just enough time to navigate to the menu, but to be on the safe side, you may like to increase this to 5.

If you do not like the default key combination of Alt+Print Scrn, you can change this by going to:


And editing the property for run_command_window_screenshot.
