By default when CentOS is installed not all the gnome utils are loaded in the system.
The screenshot utils is one of them that is not loaded.
So trying to take a screenshot would fail:
ERROR:
There was an error running gnome-screenshot: Failed to execute child process “gnome-screenshot”
Only the utilities below were available:
- gnome-about
- gnome-about-me
- gnome-appearance-properties
- gnome-at-properties
- gnome-at-visual
- gnome-audio-profiles-properties
- gnome-character-map
- gnome-control-center
- gnome-default-applications-properties
- gnome-desktop-item-edit
- gnome-display-properties
- gnome-font-viewer
- gnome-help

- gnomevfs-monitor
- gnomevfs-mv
- gnomevfs-rm
- gnome-volume-control
- gnome-volume-control-applet
- gnome-wacom-properties
- gnome-window-properties
- gnome-wm
As you can see, gnome-screenshot wasn’t there.
To install the gnome-screenshot util:
sudo yum install gnome-utils
That should fix the problem and you should be able to take screenshots as you would normally expect:
