    Post Edit bashrc in ubuntu server 21.10 change background color

    Distributor ID: Ubuntu
    Description: Ubuntu 21.10
    Release: 21.10
    Codename: impish

    trying to find how to change backround color to black ?????

    Standing in front of server with vga lcd monitor not ssh

    when server boots all text and background is fine then it changes to blue very hard to read in front of server

    please help thanks

    I did the following so far

    I used editor jed

    sudo jed ~/.bashrc

    removed " # " force_color_prompt=yes

    enable color support of ls and also add handy aliases

    here is my bashrc file

    # ~/.bashrc: executed by bash(1) for non-login shells.
    # see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
    # for examples

    # If not running interactively, don't do anything
    case $- in
    *i*) ;;
    *) return;;

    # don't put duplicate lines or lines starting with space in the history.
    # See bash(1) for more options

    # append to the history file, don't overwrite it
    shopt -s histappend

    # for setting history length see HISTSIZE and HISTFILESIZE in bash(1)

    # check the window size after each command and, if necessary,
    # update the values of LINES and COLUMNS.
    shopt -s checkwinsize

    # If set, the pattern "**" used in a pathname expansion context will
    # match all files and zero or more directories and subdirectories.
    #shopt -s globstar

    # make less more friendly for non-text input files, see lesspipe(1)
    [ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)"

    # set variable identifying the chroot you work in (used in the prompt below)
    if [ -z "${debian_chroot:-}" ] && [ -r /etc/debian_chroot ]; then
    debian_chroot=$(cat /etc/debian_chroot)

    # set a fancy prompt (non-color, unless we know we "want" color)
    case "$TERM" in
    xterm-color|*-256color) color_prompt=yes;;

    # uncomment for a colored prompt, if the terminal has the capability; turned
    # off by default to not distract the user: the focus in a terminal window
    # should be on the output of commands, not on the prompt

    if [ -n "$force_color_prompt" ]; then
    if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
    # We have color support; assume it's compliant with Ecma-48
    # (ISO/IEC-6429). (Lack of such support is extremely rare, and such
    # a case would tend to support setf rather than setaf.)

    if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
    unset color_prompt force_color_prompt

    # If this is an xterm set the title to user@host:dir
    case "$TERM" in
    PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1"

    enable color support of ls and also add handy aliases
    if [ -x /usr/bin/dircolors ]; then
    test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)"
    alias ls='ls --color=auto'
    #alias dir='dir --color=auto'
    #alias vdir='vdir --color=auto'

    alias grep='grep --color=auto'
    alias fgrep='fgrep --color=auto'
    alias egrep='egrep --color=auto'

    # colored GCC warnings and errors
    #export GCC_COLORS='error=01;31:warning=01;35:note=01;36:c aret=01;32:locus=01:quote=01'

    # some more ls aliases
    alias ll='ls -alF'
    alias la='ls -A'
    alias l='ls -CF'

    # Add an "alert" alias for long running commands. Use like so:
    # sleep 10; alert
    alias alert='notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history|tail -n1|sed -e '\''s/^\s*[0-9]\+\s*//;s/[;&|]\s*alert$//'\'')"'

    # Alias definitions.
    # You may want to put all your additions into a separate file like
    # ~/.bash_aliases, instead of adding them here directly.
    # See /usr/share/doc/bash-doc/examples in the bash-doc package.

    if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases

    # enable programmable completion features (you don't need to enable
    # this, if it's already enabled in /etc/bash.bashrc and /etc/profile
    # sources /etc/bash.bashrc).
    if ! shopt -oq posix; then
    if [ -f /usr/share/bash-completion/bash_completion ]; then
    . /usr/share/bash-completion/bash_completion
    elif [ -f /etc/bash_completion ]; then
    . /etc/bash_completion

    Re: Edit bashrc in ubuntu server 21.10 change background color

    tput setab 0
    on the console will set the background colour to black and clear the screen. This might not work in a terminal in X, at least it doesn't on xfce4-terminal because there you can set the background colour from the menu and the background gets reset to that color.

    To find out the the codes for various colours you can use
    for ((i=0;;i<16;i++)) ; do tput setaf $i;echo -n $i;done;echo foreground colours
    for ((i=0;;i<16;i++)) ; do tput setab $i;echo -n $i;done;echo background colours
    For other symbolic names for terminal capabilities look in 'man terminfo'.
