 Posted: Sat Jun 01, 2019 9:07 pm Post subject: gnome-terminal WARNING: terminal is not fully [solved] |
 |
|
I'm running Gentoo with gnome3 and systemd on a tower.
If I use gnome-terminal (3.30.3) I get the following error with 'less' and 'man'
| Code: |
WARNING: terminal is not fully functional
|
- If I use xterm on the system all is fine.
- If I ssh from a Debian 9.9 machine using gnome I get the SAME WARNING.
- If I ssh from my Gentoo laptop using xfce4 I get the SAME ERROR.
- If I ssh from my Gentoo laptop with no desktop environment. NO WARNING.
- If I ssh from a Raspberry Pi NO ERROR. 'less' and 'man' work fine. NO WARNING
gnome-ternimal is not fully functional on the tower.
? ANY IDEAS ?

I can easily reproduce this warning message if I set the TERM environment variable to an invalid value:
| Code: | $ export | grep TERM
declare -x TERM="xterm-256color"
$ man ls # works fine
$ export TERM="xghjgxgjghx" # invalid value, this terminal emulation doesn't exist
$ man ls # WARNING: terminal is not fully functional
$ export TERM="vt100" # valid value, but incompatible with my terminal
$ man ls # works fine
$ export TERM="xterm-256color" # back to default value
$ man ls # works fine
|
TL;DR: check your TERM environment variable  |

What is the ouput of
| Code: | | export | grep "TERM=" |
when you get the "WARNING: terminal is not fully functional" messages? |

I'm a slow one sometimes 
export TERM="linux"
works fine on my system.
Thanks you.

| I think TERM=linux is not correct for the graphical terminal emulators, though it is close enough that it mostly works. I use TERM=xterm-256color in x11-terms/xterm with =sys-libs/ncurses-6.1-r2 and man ls works fine for me. |

I agree. On my machine, TERM has one of the values below:
- TERM="linux" on the Linux text TTYs
- TERM="xterm" in xterm and uxterm
- TERM="xterm-256color" in konsole and qterminal
The TERM environment variable is set by the terminal itself - NOT by me and NOT by my login profiles or scripts.
@cwc: if I understand correctly, "man ls" sometimes gives you the "WARNING: terminal is not fully functional" message and sometimes not. That depends on the way you log in. But TERM is always "xterm-256color". Is that true?
If that's the case, it's NOT the TERM environment variable that is wrong. Leave it on "xterm-256color". Don't change it.
Something else is wrong. Please re-install ncurses:
| Code: | | emerge --oneshot ncurses |
Does that solve the problem? |

Did you build ncurses with the tinfo flag?
The different behaviour are "normal": ssh export the current terminal emulator $TERM when connecting:
- xterm sets TERM=xterm
- debian probably set gnome-terminal's TERM to a value that your gentoo don't know
- gentoo laptop with xfce, I don't know its TERM but probably also not know
- gentoo with no desktop is probably TERM=linux
- RPy : not idea of the TERM value |

set new profile:
[22] default/linux/amd64/17.1/desktop/gnome/systemd (stable) *
ciclo ~ # export | grep "TERM="
declare -x COLORTERM="truecolor"
declare -x TERM="xterm-256color"
ciclo ~ # export | grep TERM=
declare -x COLORTERM="truecolor"
declare -x TERM="xterm-256color"
thank you for all the posts.
