[Ubuntu] 把 shutter 設為截圖預設程式

寫得蠻清楚的！

Shutter as default
To configure Shutter as the default tool to take screenshots with when you press PrtSc or Alt+PrtSc, here's what you need to do:

• Gnome3/Unity

• KDE

• Xfce

• LXDE

1. Go to System Settings ▸ Keyboard

Gnome/Unity – System Settings

1. Switch to the Shortcut tab and add a new custom shortcut

Gnome/Unity – Add new custom shortcut

1. Enter a Name (e.g. Shutter) and a Command (e.g. shutter -f)

Gnome/Unity – Enter command

1. Click the new row and hold down the new keys in order to add/edit the accelerator

Gnome/Unity – Edit accelerator

1. That's it! Now the usual PrtSc keybinding will use Shutter to take the screenshots.
