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.

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.
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/
