== How to duplicate my XO Setup ==

<center>incomplete</center>
coming soon
=== Update the OS ===
Update the OS as soon as you reasonably can. This is because when you update the OS, you'll lose pretty much anything you've done with your XO.

<center>(This is critical, but since I don't want to update my own OS right now, I'll have to fill in details later. Otherwise, I'm afraid I'd give bad advice.)</center>

=== Get Familiar with Command Line ===

=== Pick an Editor ===
I won't walk you through all the choices of text editor. Many like [[vi]], and there's other options like [[emacs]]. In principle it's possible to use the [[Write]] activity.

I use [[nano]].

=== Install Firefox ===

=== Modifying Activities ===

==== Give Browse a Home Page ====

==== Gamepad Zoom in Read ====

=== Tweaking Sugar ===
Some of the changes I've made are changes to the Sugar UI itself.

==== Pre-Tweaking Precaution ====

<b>Prevent X Restarting</b>

First, however, I strongly recommend a precautionary change. By default, X (the graphical environment Sugar runs in) restarts itself automatically. That means if something goes wrong as Sugar is starting, it quits and dumps out to the console, and then restarts and so on loops and loops and it's very hard to fix.

[[Michael Stone]] gave me good advice to prevent this from happening [http://en.forum.laptop.org/viewtopic.php?f=2&t=2570#p8960 at the forum]. Before making any (even minor) tweaks to Sugar, I follow that advice.

==== Practice Tweak--Background Color ====
Just to get familiar with making changes to Sugar, and because it's fun to personalize, how about changing the background color of the Home view?

==== Turn Off Register ====
Since we're never going to to register our XO's with a school server, we don't need to be reminded regularly. So we might as well take that out. It's a minor point, but it's also a minor edit.

----
in /usr/share/sugar/shell/view/frame/HomeBox.py

Simply comment out the following lines:
# if not self._profile.is_registered():
# item = gtk.MenuItem(_('Register'))
# item.connect('activate', self._register_activate_cb)
# palette.menu.append(item)
# item.show()

----

==== Turn Off Hot Corners ====
There's at least one thing about the standard Sugar interface which most users want to change. (I think it might change by default in future updates.) The [[OLPC Human Interface Guidelines/The Laptop Experience/The Frame#Hot_Corners|hot corners]] are very annoying for me, and many others. They also feel unnecessary since you can accomplish the same thing(s) by pressing the special navigation buttons.

----
This requires just commenting out two lines in /usr/share/sugar/shell/view/frame/eventarea.py:
def _create_invisible(self, x, y, width, height):
invisible = gtk.Invisible()
# invisible.connect('enter-notify-event', self._enter_notify_cb)
# invisible.connect('leave-notify-event', self._leave_notify_cb)

That's all that's needed.

----
==== Add a Clock to Home View ====
It's very unusual these days to have any electronic device which doesn't tell you what time it is. There are a couple full-fledged clock activities ([[Clock activity|clock]] and [[Alarm Clock, Randomizing WAV/MP3|random tune alarm clock]]), but they're overkill for a constant clock.

----
To add a clock, I create one new file and modify one existing file. Both files are in /usr/share/sugar/shell/view/frame

The existing file which gets modified is zoomtoolbar.py. First, up top in the imports it needs:
from frameclock import FrameClock

Down actually in the code of zoomtoolbar.py:
palette = Palette(_('Activity'))
palette.props.invoker = FrameWidgetInvoker(button)
palette.set_group_id('frame')
button.set_palette(palette)

# new clock code here
clock = FrameClock("%a %b %d %I:%M %p") # Show day month date HH:MM AM/PM
# clock = FrameClock("%D %H:%M:%S") # show date & time through seconds
# self.insert(clock,0) # Put clock to left of navigation buttons
self.insert(clock,-1) # Put clock to right of navigation buttons
clock.show()
clock.start()

You see above that there are format choices. You can use [http://docs.python.org/lib/module-time.html time format] codes in the call to FrameClock() to get the format you like. And you can decide when you do insert(clock...) whether you want the clock on the left or the right of the navigation buttons.

This requires a definition of FrameClock, which happens in the new file, frameclock.py:
# frameclock -- a little digital clock widget for the Home frame
# Actually, there's nothing about this specific to that use, could
# be used as a widget anywhere.
# March 28, 2008 Timothy Dang
from gettext import gettext as _
import gtk
import time
import gobject
import string
import pango
class FrameClock(gtk.ToolItem):
def __init__(self,new_format="%D %H:%M:%S"):
gtk.ToolItem.__init__(self)
self.set_expand(True)
self.format=new_format
self.update_interval = 1000 # update every second (recommended)

def start(self):
self.label = gtk.Label(time.strftime(self.format))
self.add(self.label)
self.label.show()
self.update_timer = gobject.timeout_add(self.update_interval,self.update)

def update(self):
time_string = time.strftime(self.format)
self.label.set_markup("<big>"+time_string+"</big>")
self.label.show()
return 1 # This seems to be needed to continue the update_timer

That should give you something which looks like:
