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.
