fbdump (captures the visible portion of framebuffer to stdout)
-fbdump is a simple tool that captures the contents of the visible portion of
-the Linux framebuffer device and writes it to the standard output as a PPM
-file. In other words, it takes a screenshot of anything running on the
-framebuffer. It currently has fairly complete support for packed-pixel
-framebuffer types and also works with the VGA16 framebuffer driver.

To get a popular image format, issue a command like:
fbdump | pnmtopng > shot.png
Note: fbdump is rather slow on modern systems with high-resolution
-framebuffers at 32-bit color depth. On the maintainer's system, it takes
-8 seconds to dump a 1920x1080x32 framebuffer. Be patient.
