This page is a running review of what I found out on the XO laptop beginning December 21, 2007. I purchased the laptop with 20 friends at work in the 2 for 1 deal. The information was obtained through trying it out and various help pages on http://laptop.org and http://wiki.laptop.org. Feel free to contribute to help us laearn more about using the laptop. This document was started with vi in the Terminal Activity and copied to the Write Activity using the Browser Activity to see the file system. It was, in turn, copied to this page. Liberal use was made of ctrl-a to select all, ctrl-c to copy, and ctrl-v to paste. All of the editing was performed with the XO laptop. See also at the bottom of the page has useful links.

Questions/Problems

Collaboration: How tp I get together with other laptop owners in Fremont, Palo Alto, or Mountain View, California? I expect a lot of people from Google bought it, so I can probably go there.
How to switch the screen between color to black and white
Where do the activities actually store the files.
When will we geet a print capbility, maybe lpr.
Sometimes the touchpad goes haywire; reboot fixes; maybe a memory management problem
Wireless does not support wpa encryption. wep works. I used shared key with HEX. I needed a reboot to make it work.
How to listen to an mp3 file:
- If downloaded from the web, a Journal entry is created, but it only seems to let you do it once in Etoys. It fails the second time.
Why is my touchpad jumpy or ue a USB mouse.
a*if it is on a USB drive, use the Journal to launch it. It launhes in Etoys. It plays one file at a time.
Spreadsheet: This killer app is not ready yet. It is listd on the download page as in development. Google online spreadsheet can be used

Journal Activity

This should be the focus for running the activities
It is best to resume a journal entry to reduce the numbr of entries.
Clean up is slow because you can only delete journal entries one at a time.
USB drives can be plugged in and accessed from the journal. Files can be opened from the drive at the bottom of the screen. A journal entry can be dragged to the Drive icon to copy.
Downloaded files from the Browse Activity can be accessed from thr journal.
What does the * mean in the journal? In gmail, a star can be selected as an object for an action.

General

Specs http://wiki.laptop.org/go/Hardware_specification:

Copy and Paste: Clipboard is on the left side of the Home view. This stores copy (ctrl-c) and cut (ctrl-x). Paste (ctrl-v) can be used in Write and other activities. Also see #Terminal Activity
USB drives: see #Journal Activity
MP3 files can b played from the Journal with Etoys or Write and Listen Activity. Write and listen needs to be insatlled. See [[http://wiki.laptop.org/go/Support_FAQ#How_do_I_play_sound_files.3F%7CHow_do_I_play_sound_files
Screen Capture: alt-1 can be opened in the Journal Activity which launhes a Browse Activity on a png file in file:///home/olpc/.sugar/default/data/. Info from Keyboard Shortcuts.
How to get version (build 650, for example mentioned on the browse wiki page
Volume control: buttons on keyboard and some activities have a slider.

Get1_donors_access_their_free_year_of_T-Mobile_wireless_Internet

Terminal Activity

Man pages are not loaded so I went to http://www.linuxmanpages.com
Terminal can access usb drive. It is mounted on /media. df shows the mount.
ls (to list directory) cd (to change directory)
cp (to copy files) vi (to edit files)
find . -name "*.log" find . -mtime -1 -ls
/sbin/ifconfig -a gives Ethernet and MAC address under eth0.
su - to become root user.
Set Date and timezone

su -
export SUGAR_PATH=/usr/share/sugar
sugar-control-panel -s timezone America/Los_Angeles
date 01010957   for January 1, 9:57

Copy and Pate in Terminal Activity;
- When a mouse is attached let button to highlight an copy, middle button to paste. This does not go to the clipboard. The touchpad does not copy and paste.
- USB drive is mounted on /media. cp can be used to copy.
- To copy to the Write Activity (top df exampe):

    df > memory.txt             to write into  file
    top -b -n1 >> memory.txt    to append to the file
    Type / in the Browse Activity and then browse to home/olpc to find the file
    Text can then be copied.

Screen capture has not been tested
How to copy and paste

Write Activity

Search is in edit, it is good but it should be hooked upto ctrl-f
Spell check, but does not list suggestion; How to add a word to the list (not in /usr/share/dict)
auto page break
Write can save (keep) as html and rtf
Insert image only goes to journal with poor choices
There seems to be no way to open a file, for example, /etc/hosts. See #Terminal Activity for how to copy text.

Browse Activity

FullScren: alt-enter toggles
View Source: cyrl-U does a view source for web pages but is really slow
Adobe Flash install to get, for example, pandora.com, bloglines.com, and ebaumsworld.com, to work
Downloaded files from the Browse Activity can be accessed from thr journal.
How to tell what web site you are going to (no status bar)
Bookmark is awkward as shown in How_do_I_bookmark_a_website_and_browse_it_later
Cannot search in browse

Brainstorming

Find python spreadsheet and install it
Make your own activity, maybe a unix command (for example, find) but tie it to an actiity
Write tetris and install
Talk to Ken Gamble about online comunity and physical community.
Voice recognition and intruder alert
Picture or video processing using the camera (intruder alert)
Speech recognition (voice list application)
Use a lot of online apps
Screen capture: it looks like you get a screen capture called screenshot when you copy something to the clipboard. It is stored in /home/olpc/.sugar/data which you can get to from the journal
Install linux and sugar on another PC so we can work with it without the laptop. Emulating_the_XO
See what the kids have done so far, for example, Peru.

Keyboard

See Keyboard Shortcuts and http://laptop.org/keyboard
top row: esc search(journal) neighborhood friends home activity
Panels next to the touch pad are for future activies, maybe with a pen. They are resistive rather than capacitive like the toughpad.
Hand key next to alt: it is shown on the web getting started, as not used yet
alt-enter toggles full screen mode which can be used in write, browse
fn-erase erases from the right
alt-f is the same as frame button on the upper right this works in write but not in main view
alt-n goes to journal
alt tab cycles through the activities
alt-p also cycles through the activities
alt-r rotates the screen as well as the button on the lower left of the screen
