    Default Nvidia driver problems install....

    I am following this process with installing nvidia drivers and cuda

    http://www.backtrack-linux.org/wiki/...A_On_BackTrack

    everything seemed to install fine but when i get to this part:

    Ideally you should install the CUDA toolkit to /opt. this guide assumes this installation path. Configure your environment variables so that the nvcc command works. You can do this by appending the following lines in your /root/.bashrc file:

    PATH=$PATH:/opt/cuda/bin
    LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/cuda/lib
    export PATH
    export LD_LIBRARY_PATH
    THEN RUN:
    root@bt:~# source /root/.bashrc
    root@bt:~# ldconfig
    I get this response when i run "source /root/.bashrc"

    root@bt:~# source /root/.bashrc
    bash: /opt/cuda/bin: is a directory
    Below is my edited /root/.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
    if [[ -n "$PS1" ]]; then

    # don't put duplicate lines in the history. See bash(1) for more options
    # ... or force ignoredups and ignorespace
    HISTCONTROL=ignoredups:ignorespace

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

    # for setting history length see HISTSIZE and HISTFILESIZE in bash(1)
    HISTSIZE=1000
    HISTFILESIZE=2000

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

    # 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)
    fi

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

    # 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
    force_color_prompt=yes

    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.)
    color_prompt=yes
    else
    color_prompt=
    fi
    fi

    if [ "$color_prompt" = yes ]; then
    PS1='${debian_chroot:+($debian_chroot)}\[\033[01;31m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
    else
    PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
    fi
    unset color_prompt force_color_prompt

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

    # 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'
    fi

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

    # 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
    fi

    # 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 [ -f /etc/bash_completion ] && ! shopt -oq posix; then
    # . /etc/bash_completion
    #fi
    export HISTCONTROL=ignoreboth
    fi

    export PATH=$PATH:/etc/alternatives/gem-bin

    PATH=$PATH: /opt/cuda/bin
    LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/cuda/lib
    export PATH
    export LD_LIBRARY_PATH

    Im not sure what it is i have done wrong....and yes i did install cuda to /opt

    Please help, Im still pretty new so im sure its just a dumb user mistake but i cant seem to figure it out. and google didnt help nor did i see anything related in the forums.

    Just remove the space between "PATH=$PATH:" and "/opt/cuda/bin" and it should work fine.

    export PATH=$PATH:/etc/alternatives/gem-bin

    PATH=$PATH: /opt/cuda/bin
    LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/cuda/lib
    export PATH
    export LD_LIBRARY_PATH
    Reavernine,

    Try this
    Code:
    PATH=$PATH:/etc/alternatives/gem-bin:/opt/cuda/bin
    export PATH
    LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/cuda/lib
    export PATH
    export LD_LIBRARY_PATH
    V/r,
