¿Cómo hacer capturas de pantallas en Debian ?

Traducción(es): ?English

Usando Gnome

Gnome trae, por defecto, la funcionalidad de hacer tomas de pantalla (utilizando el paquete gnome-utils); para ello puede seguir los siguiente métodos:

• Tecla "Impr Pant" o su equivalente, que hará una captura del todo el escritorio.
• Combinación de las teclas "Alt+Impr Pant (o equivalente)" para hacer una captura sólo de la ventana activa.

  

Otras opciones están disponibles en el Menú Aplicaciones --> Accesorios --> Capturar Pantalla

• Leer la página del manual en línea gnome-screenshot(1) y la ayuda de la aplicación "Capturar Pantalla" para mayor información.

Using KDE

KDE has the capability to make a screenshot (using package ksnapshot). Simply press:

• "Print Screen" key to take a screenshot of the whole screen.

  

Read ksnapshot handbook for more information.

Using command line

Just open a graphical terminal and type:

•  sleep 5; xwd -root | convert - capture.png
  or 
   sleep 5; xwd -root | xwdtopnm | pnmtopng > capture.png

The command xwd is a standard xorg tool, which creates a pnm file. you can then use imagemagick 's convert, or netpbm 's xwdtopnm tool)

A powerful alternative tool is scrot, which can directly save files as png (and other formats), and generate a filename. see scrot(1).

Console / Xterm

Rather that making a graphical snapshot of the console/command line or X-window terminal, it's usually better to copy the actual text content (select the region with a mouse).

Console

To you use the mouse on the Console screen, you need to install gpm (run apt-get install gpm).

• Select the region to copy by pressing the mouse's left-button, then drag.
• Open your favorite text editor, then paste the selected text using the right button.

advanced tip: if you don't want to use a text editor, you can run cat > /tmp/outfile.txt, then paste the content using right-button, then press Ctrl-D (once).

Framebuffer

If your system is using framebuffer (vga=XXX kernel argument, etc..), you can use fbgrab to capture and convert the framebuffer content.

• fbgrab fb.png screen.png

  Hint: If fbgrab isn't installed when you want to capture the screen, you can use cp /dev/fb0 screen.raw, then use fbgrab -f screen.raw -w 1024 -h 768 -b 16 screen.png

Other Tools

Debian provides some other (advanced) tools to make screenshot, including gimp .

Debian Installer GUI screenshots

DebianInstaller's GUI has a take "Screenshot" button.

To fetch the captured screen :

• Click "Go Back" until you get to the main menu of the installer (this can be postponed until a later point in the installation).
• Select the "Save debug logs" option.

• Select one of the three option : "floppy", "web server" or "mounted filesystem". (The web server way is very convenient if you have another computer around).

• Then follow the instructions in the next dialog.
• When you get back to the menu, resume the installation at the next step (which should be the one that is selected when the menu is displayed).

If you complete the installation, the screenshots can also be found in the directory /var/log/installer/ (after the reboot into the installed system).

License of screenshots

Screenshots are considered as derivative works (according to SPI legal counsel), see http://lists.debian.org/debian-legal/2008/08/msg00016.html.
