Hi, I switched to console 1 (Ctrl + Alt + F1) and tried:

export DISPLAY=:0.0
sudo gnome-screenshot

Which gives a black image with just the mouse cursor. It's nothing critical, but something I'd like to do. Any help appreciated :-)

Running Ubuntu 10.04 Lucid Lynx

How to create a screen shot of the GDM login screen on Ubuntu

This blog pts explains how to create a screen shot of the currently running X11 GDM login screen (the graphics login screen at system startup) on Ubuntu.

  1. Install ImageMagick for the image file format conversion below:

    $ sudo apt-get install imagemagick

  2. Create a helper script:

    $ echo 'DISPLAY=:0 XAUTHORITY=/var/lib/gdm/:0.Xauth xwd -root' >/tmp/shot.sh

  3. Make sure your login screen is active (log out or reboot the machine, and wait until you see the login screen).

  4. Log in in text mode (by pressing Ctrl-Alt-F1), or using SSH.
  5. Create the screen shot by running

    $ sudo bash /tmp/shot.sh >/tmp/shot.xwd

  6. You can log in now (by pressing Ctrl-AltF7 first to get back to the GDM login screen).

  7. Convert the screen shot to JPEG and/or PNG:

    $ convert -quality 50 /tmp/shot.xwd /tmp/shot.jpg $ convert /tmp/shot.xwd /tmp/shot.png

  8. View the screen shot in your favourite image viewer.

Thanks, but the resulting image is just black.
