To be able to use tools like gnome-screenshot or xfce4-screenshot one has to be logged in and with access to the desktop.
But what about capturing previous screens? That would have to be done in the console.
I do not imagine that the grub screen can be captured.
But what about the next ones?
- The login window, the one for user and password
I have found some answers, like here. But I am in (Linux Mint 14) Xfce and I tried to replace
xdm in the line
$ echo 'DISPLAY=:0 XAUTHORITY=/var/lib/gdm/:0.Xauth xwd -root' >/tmp/shot.sh
I get the error
no protocol specified xwd: unable to open display ':0'
- What about the following screen, to select the type of desktop?
- And after that, the one to select between saved sessions?
(for which I could not find an image on the internet)
