[HOWTO]Change ls command default colors

1.Test colors supported
This shell script shows all standard colour combinations on the current console.
If no colours appear, your console does not support ANSI colour selections.

    #!/bin/bash
    # Display ANSI colours.
    #
    esc="\033["
    echo -e "\t  40\t   41\t   42\t    43\t      44       45\t46\t 47"
    for fore in 30 31 32 33 34 35 36 37; do
      line1="$fore  "
      line2="    "
      for back in 40 41 42 43 44 45 46 47; do
        line1="${line1}${esc}${back};${fore}m Normal  ${esc}0m"
        line2="${line2}${esc}${back};${fore};1m Bold    ${esc}0m"
      done
      echo -e "$line1\n$line2"
    done

2.Customize your ls output colors
first copy /etc/DIR_COLORS to HOME/.dir_colors.
then modify .dir_colors to your preferred themes(see comments in files).
by default, bash will use your cutomized colors next time when you open a new shell window.

NOTE: dircolors -p to view current color scheme.

Points to Speed up YaST

By default, Yast with activate and check update for every repository entries you setup.
So it will be faster if you disenable those default options.
Better options:
1.check update by manually, don't let YaST check it every time.
2.keep only main repositories activating, disactivate temporary repositories.
only use temporary entries when you need.

Unfortunately, my Toshiba laptop is not in the s2ram whitelist.
First find out proper options that work for you.
In my case, "sudo s2ram -f" works fine. You can find some test options combinations in http://en.opensuse.org/S2ram.

Second modify opsensuse options.The default is s2ram, no other options are set in openSUSE.
sudo vi /etc/pm/config.d/s2ram
add follow lines:
