[SOLVED] How do I take a screen shot of a XWindow?

Hi,

I'm using Ubuntu 11.04. In a startup script, I have

Code:

start() {
        log_daemon_msg "Starting selenium-server server: "
        export DISPLAY=localhost:15.0
        /usr/bin/Xvfb :15 -ac -screen 0 1024x768x16 &

From the console, how do I take a screen shot of the display at localhost:15.0 -- my DISPLAY above?

Thanks, - Dave

Code:

xwd -display localhost:15.0 -out /tmp/desk.xwd -root

xwd format isn't readable by everything but can be converted by common graphics programs like the Gimp.

Use ImageMagick:

$ /usr/bin/import -display localhost:15.0 -window root screenshot_filename.jpg

Thanks for the replies. The xwd worked for me. Sadly, the ImageMagick command only generated blank screens. - Dave
