Some Activities are 'protected', that is they can't be deleted. This also means that the Activity can't be downgraded or crossgraded  to the same revision number.
 +
 +
To achieve this you need to delete the Activity's directory in
 +
 +
/home/olpc/Activities
 +
 +
This is easily done in older builds in Gnome but newer builds have a hidden and protected Activities directory
 +
 +
sudo gedit
 +
 +
allows you to edit files but not delete
 +
 +
chmod 777 ~/Activities
 +
chmod 777 ~/Activities -r    #contents too?
 +
 +
unprotects the directory but it is still hidden, in the file manager <i>nautilus</i> check show hidden files
 +
 +
 +
To automate this every time Gnome starts, add the following 2 commands to System, Preferences, Startup applications
 +
 +
  rm .hidden
 +
  chmod 777 Activities
 +
 +
==Enabling debug output==
 +
Edit /home/olpc/.sugar/debug and uncomment :
 +
  export SUGAR_LOGGER_LEVEL=debug
 +
 +
==Starting Gnome==
 +
If not in my settings
 +
echo gnome > /home/olpc/.olpc-active-desktop
 +
and restart
 +
 +
 +
==Setting the clock==
 +
From firmware, using the internet, networkname is your modem/router eg DLINK
 +
ok  essid networkname
 +
ok  ntp-set-clock pool.ntp.org
 +
ok  .clock
 +
Worked despite timeout message

==Text dungeon==

A text dungeon game for literacy and numeracy
 +
 +
Most of this page transferred to [[Activities/Textdungeon]] , just the command line version here
 +
 +
[[File:Text dungeon.jpg|300px]]
 +
 +
The dungeon [[File:Sampledungeon.doc | description file]]
 +
 +
[[File:Textdungeon.doc | the program]] is a version of the program's Python code which works from the command line
 +
 +
[[File:Textdungeon1.xo]] is a Sugarised install bundle, works Sugar 0.88 - 0.92
 +
 +
[[File:Textdungeon2.xo]] Sugar compliant icon, do not load sample file if resuming, backspace supported, journal entry saves progress)
 +
 +
 +
===Keyboard commands===
 +
h - help
 +
 +
f - forward
 +
 +
r - right
 +
 +
l - left

==Screenshots in Sugar==
 +
===Simple screenshot===
 +
To take screenshots press Alt 1
 +
 +
This will capture the screen but not the mouse cursor
 +
 +
===Screenshot with cursor===
 +
To also capture the mouse cursor, install gnome-screenshot. Type the following in Terminal:
 +
 +
sudo yum install gnome-utils
 +
 +
You can then start the interactive version of gnome-screenshot:
 +
gnome-screenshot --interactive
 +
 +
[[File:Gnome-screenshot.png|350px]]
 +
 +
Check that you have the right options selected and that 'Include pointer' is selected, then click Take Screenshot. Do not navigate away to the screen you want the screenshot of because you will be unable to navigate back to the utility. At this point we are just checking that the options are correct.
 +
 +
[[File:Gnome-screensh-2.png|350px]]
 +
 +
Select a suitable save location such as 'Documents' and click Save.
 +
 +
Now you are ready to take a screenshot. Start gnome-screenshot from Terminal with a suitable delay, eg. 2 seconds
 +
 +
gnome-screenshot -d 2
 +
 +
Immediately go to the screen you wish to capture, position the cursor where you want it, get the menus etc. as you want them and wait for the dialog box. Click Save. (Later versions of Sugar allow you to access the saved file in Documents but the folder contents are not updated, you may need to switch between Journal and Documents to see the updated file listing.)

 +
 +
==GIT and patches==
 +
===GIT local repository===
 +
sudo install git
 +
 +
clone the git of the Turtle, in a terminal, make:
 +
 +
git clone  git://git.sugarlabs.org/turtleart/mainline.git
 +
 +
In the mainline folder there are all turtle's files..
 +
 +
===Patch===
 +
sudo yum install patch
 +
or
 +
sudo yum install patch --nogpg
 +
 +
Should be a "raw patch" link (eg. 2b4ecb0cc7095f47fc944c54512e055c21537ab5.patch)
 +
 +
1. Save that page as a file into ~/Activities/TurtleArt.activity  (eg patching Turtle Art)
 +
 +
2. From terminal run the patch command as follows:
 +
 +
patch -p1 < 2b4ecb0cc7095f47fc944c54512e055c21537ab5.patch
 +
 +
That is it. (Note, you should be able to use autocomplete when typing
 +
the command line by hitting tab after typing the first few letters of
 +
the patch file name.)
