Maybe I'm misunderstanding something in your response, but you
shouldn't test the return value of echo. Test the $DISPLAY env var:
if exists('$DISPLAY')
" running under X11
else
" running on console
endif
I have had some success using:
if &term=~'cons25'
colorscheme myvim
elseif &term=~'xterm'
set t_Co=256
colorscheme calmar256-dark
endif
but the strange thing is, if $TERM is set to xterm and not
xterm-256color, gkrellm locks up... something to do with the email
part of it.
If I could just find where xterm is being set and change it to
xterm-256color without altering tty mode's TERM settings (i.e.
cons25) I'd be laughing.
For me, here are some environment variables that are different between
a 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:
COLORTERM=rxvt
DISPLAY=:0.0
WINDOWID=92274697
WINDOWPATH=7
XAUTHLOCALHOSTNAME=bhaskell-pc
XAUTHORITY=/home/bhaskell/.Xauthority
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 /etc/skel/ has:
TERM=cons25; export TERM
Maybe that's the problem.
Otherwise, I would think $SHLVL and $WINDOWID would be your best chances.
e.g.
if exists('$SHLVL') && $SHLVL < 2
" probably running on console
else
" running under X11
endif
or:
if exists('$WINDOWID')
" under X11
else
" on console
endif
Thanks Ben,
the $DISPLAY version doesn't work (I get red screen and flashing text in
text mode)
however, both $WINDOWID and ('$SHLVL') && $SHLVL < 2 do work.
I think I like the $WINDOWID version best. It feels ... ??cleaner??. I
don't know why because, without looking it up, I don't even know what
$SHLVL is. I suspect it's shell level and if we're running in the first
level of the shell, then it's likely to be text console given that
that's what I first log into. Am I right?
