[Learn OpenCV Introduction] [001] [Ubuntu installation and configuration]

Learning environment:

1. Operating system UBUNTN

2. Study book "Learning OpenCV"

3.OpenCV version opencv-1.0.0

Root Login Configuration

UBUNTN does not allow the root user to login by default, only ordinary users and guest users can be seen in the login window. We do development need to use root permissions often, so the root user is set to automatically log on users.

1. After logging in as a normal user, enter in the terminal:

sudo passwd root to add a password to the root user.

2.su root, switch to root user.

3.vim/etc/lightdm/lightdm.conf, modify the configuration file as follows:

[Seatdefaults]

User-session=ubuntu

Greeter-session=unity-greeter

Allow-guest=false

Autologin-user=root

Autologin-user-timeout=0

Autologin-session=lightdm-autologin

4. Restart the system, do not need to enter the user name and password is good to automatically enter the root user.

Terminal Path Configuration

Ubuntu will currently display the current path in the terminal, and sometimes it will appear long when the file path is very deep. So setting the terminal path here does not echo.

1.vim ~/.BASHRC, edit the lowercase w in the line below, and change to uppercase W. Indicates that only the current directory name is displayed.

If ["$color _prompt" = yes]; Then    PS1 = ' ${debian_chroot:+ ($debian _chroot)}\[\033[01;32m\]\[email protected]\h\[\033[00m\]:\[\033[01;34m\] \w \[\033[00m\]\$ ' else    PS1 = ' ${debian_chroot:+ ($debian _chroot)}\[email protected]\h:\w \$ '
