test the return value of echo. Test the $DISPLAY env var:
" running under X11
" running on console

shell running on a virtual console and a shell session running under
rxvt-unicode under X11:
X11: TERM=rxvt-unicode256 console: TERM=linux
X11: SHLVL=4 console: SHLVL=1
These are not present at all on a vt:
You shouldn't have a DISPLAY variable set under a console session, as
it's meaningless. (Doesn't mean you won't get one -- might be
erroneously set up by default.)
You're also right to question a TERM=cons25 when running under X11; that
sounds as broken as $DISPLAY. Do you have something in a .profile,
.bash_profile, or .bashrc?
Actually, on a FreeBSD box that I have access to, the .profile file from
TERM=cons25; export TERM
Maybe that's the problem.
Otherwise, I would think $SHLVL and $WINDOWID would be your best
if exists('$SHLVL') && $SHLVL < 2
" probably running on console
" running under X11
" under X11
