https://www.maketecheasier.com/take-screenshot-of-login-screen-linux/ is the closest I
have found
to instructions to use ImageMagick to get one, but tdm seems to be different from lightdm
and gdm
such that I can't figure out what to change. I tried logging in and grepping
XAUTHORITY from set,
but it apparently cannot be found there.
I want a fullscreen screenshot that has the integrated default theme's menu expanded
to show the
selection of session types. Can anyone here help?

You can search in: /var/run/xauth/

I don't see any connection. e.g. in Stretch I see (only):
/var/run/xauth/A:0-TZtcAa
44 binary bytes owned by root and containing string "MIT-MAGIC-COOKIE-1". On
openSUSE it's the same
except for the last 6 characters of the filename. How can that be translated to
/var/lib/gdm/$DISPLAY.Xauth
or
/var/run/lightdm/root/$DISPLAY
???
Would it be simply
/var/run/xauth/$DISPLAY
or something else?
I tried putting
#! /bin/bash
chvt 7
DISPLAY=:0 XAUTHORITY=/var/run/xauth/$DISPLAY xwd -root
in the script, but the resulting output image is always 0 bytes, and error messages:
No protocol specified
xwd: unable to open display ':0'
I tried on Tubuntu 18.04/14.1 with same result.

First, for XAUTHORITY should be: XAUTHORITY=/var/run/xauth/A${DISPLAY}-*
Second, I do not see in the man page that xwd would accept the environment
variable XAUTHORITY or option like -auth or -xauth.

Hi,
One way to do a screenshot of TDM is to run it in VirtualBox, and then take a screenshot
with the host OS (can be linux too).
Have a great day!

You can search in: /var/run/xauth/
1:30 a.m.
Or you can use x11vnc to enable remote access by VNC client:
x11vnc -display :0 -auth /var/run/xauth/A:0-*

First, for XAUTHORITY should be:
XAUTHORITY=/var/run/xauth/A${DISPLAY}-*
This works:
DISPLAY=:0 XAUTHORITY=/var/run/xauth/A${DISPLAY}-msFdGa import -window root iitdm.png
These do not
DISPLAY=:0 XAUTHORITY=/var/run/xauth/A${DISPLAY}-* import -window root iitdm.png
DISPLAY=:0 XAUTHORITY=/var/run/xauth/A${DISPLAY}* import -window root iitdm.png
Of course, the one that does work requires lookup of the content of /var/run/xauth/ after
a reboot.
Second, I do not see in the man page that xwd would
accept the environment
variable XAUTHORITY or option like -auth or -xauth.
I don't know why the URL I was working from used xwd instead of import.
Another URL that fails to provide a way that works, it too is for gdm:
https://www.howtoforge.com/how-to-take-a-screenshot-of-your-login-screen
Search on kde.org only found shooting desktop with Spectacle, not greeter.

You can use find in subshell:

Thanks! It almost gave what I wanted first try. The image isn't the problem. The
content
is. How can I make the duplicates (TDE IceWM IceWM TDE) in the session type selection
list
not appear?

Assuming I ever get what I actually want, is there someplace to save to for use by Wiki
pages? Do they need to be any particular type, e.g. .png or .jpg?
