Sage 4.2 Lightweight LiveCD v.2.5


Boot sequence
=============

In this version after booting the LiveCD (from a pen drive, CD, etc),
you will be automatically logged in a fluxbox session. It takes about
a little more than a minute to boot up depending on your hardware.


Fluxbox session
===============

You won't see any icons, just a small bar in the bottom center of the
screen with a clock and two arrows. The arrows are meant to switch between
windows but there are a couple simple key sequences to do the same (they
will be described below). The bar auto hides and the only icon you will 
see on it is the network manager one, if you invoke it.

When you click the right button of your mouse a menu will appear having Sage
as the first option, then Firefox and so on. Left click in the option and it
will be running. You can hide the menu clicking the left button of your mouse
outside the menu. Finally in the menu there's a reboot and power off option.

Instead of using the arrows of the bar to change between windows, you can
use Alt + Tab to move forward and Alt + Shift + Tab to move in reverse.


Saving your worksheets
======================

Whether you run the LiveCD from a pen drive or a CD if you want to download a
worksheet (sws file) after you do it, a dialog box will appear and as default
will have the save radio button enabled. You have to change it to Browse and
browse /usr/bin/xfe. Once you are done check the always do this option in the
dialog box. When you press the ok button you will see your sws file in xfe and
choose where to put it. The best option is to mount a usb drive in /media/usb
so you copy your file there.

Unless you are using Vmware one of the best options is to run the LiveCD from
a pen drive since you'll have to do that steps once and then it will remember
the action and saving your data will be effortless.

Another reason why you should use a pen drive is performace. The data transfer
rate between the pen drive and the computer will always be much more than a CD's.


Burning the LiveCD on a pen drive using Ubuntu based distributions
==================================================================

First format a pen drive entirely. If you use Ubuntu, plug the pen drive and then
umount it. Then open a terminal and type "sudo su", after you type your password
type "fdisk -l", that will list all the disks connected to the computer. Typically
you'll have only the one you want to format connected, for example "/dev/sdb1".
Then type "mkfs.vfat /dev/sdb1", you'll see this "mkfs.vfat 3.0.1 (23 Nov 2008)"
(or something alike) and then will be returned to the prompt. MAKE SURE THE DISK
YOU CHOOSE TO FORMAT IS THE USB, OTHERWISE IT WIPE OUT EVERYTHING IN YOUR MAIN DISK
FOR EXAMPLE.

Unplug the pen drive, plug it again and close its window. Then go to System/
Administration/Create a USB startup disk type once again your password and you 
will see your pen drive listed as a device. Click on the other button and choose
the ISO image of Sage Lightweight Live CD. Leave 250 MiBs assigned to save your
data in the pen drive and then click the Create startup disk button.

After it finishes you'll have a bootable usb with Sage Lightweight LiveCD on it.
When you reboot make sure you choose usb in your machine's boot sequence, otherwise
it won't load.

If you have any doubts google "format usb ubuntu"


Burning the LiveCD on a pen drive using other operating systems
===============================================================

If you don't have a computer running Ubuntu where you can burn the ISO the way is
described above, then the way to go is using a program called "UNetbootin". You
can download it at: "http://unetbootin.sourceforge.net/". There is explained
everything you need to know, step by step.


Bash aliases
============

There are four bash aliases you can type from the Terminal:

tzconf  To set the time and zone data so that the clock in the bar shows
        the correct time.

usb     To access automatically to /media/usb/ in case you mounted a usb in
        that path.

dce     To drop the caches as in the menu.

hu      To access automatically to /home/ubuntu/


Contact/Feedback
================

You can write to sagelwlcd@gmail.com or post in sage-devel in order to make
suggestions, comments, reporting bugs of the LiveCD, etc. Any feedback will
be appreciated. If the requirements are reasonable they will be taken into
account as in past releases.
