Is there a way for me to take a screenshot in a virtual console?
There's an application called
fbgrab that (as the name might suggest) grabs a shot of the current framebuffer. This might not work on newer KMS setups.
sudo apt-get install fbgrab fbgrab screenshot.png
If that fails, you could always use a VM in VirtualBox.
If you want to take a picture of another TTY,
fbgrab takes a
-c N argument (where
N is replaced with the
/dev/ttyN you're using).
So if you wanted tty1:
sudo fbgrab -c 1 Desktop/tty-screenshot.png
To take a screenshot of the first virtual console (AKA screendump) and save it to a file called "screenshot":
sudo cat /dev/vcs1 > screenshot
Using this method, the screenshots are saved in plain text format, not an image (check this with
mimetype command). It simply outputs a screen dump and then EOF. Note that the output does not contain newline characters, so some processing may be required:
sudo cat /dev/vcs1 | fold > screenshot
fold wrap each input line to fit in specified width (80 by default).
You cannot take the screenshot of a virtual console when graphics is enabled.
