I spent some times in Uruguay working on accessibility topics and I<br>
proposed the usage of this software:<br>
<br>
<a href="http://magnifier.sourceforge.net/" target="_blank">http://magnifier.sourceforge.net/</a><br>
<br>
Later, Esteban Arias from Plan Ceibal (who I am CCing in this mail)<br>
modified the source code to obtain better results on the XO-1.<br>
<br>
Plan Ceibal deployed the magnifying software on all the laptops in the<br>
country.<br>
<br>
It has been quite a long time since I instaled it for the first time,<br>
but if you want to give it a try here are the terminal commands you need<br>
to execute on an XO-1 to get it installed:<br>
<br>
wget<br>
<a href="http://downloads.sourceforge.net/project/magnifier/magnifier%20for%20Linux/3.3.2/magnifier-3.3.2-1.i586.rpm?use_mirror=switch" target="_blank">http://downloads.sourceforge.net/project/magnifier/magnifier%20for%20Linux/3.3.2/magnifier-3.3.2-1.i586.rpm?use_mirror=switch</a><br>
sudo rpm -i magnifier-3.3.2-1.i586.rpm<br>
sudo yum install xbindkeys<br>
touch .xbindkeysrc<br>
echo "# Virtual Magnifying Glass" >> .xbindkeysrc<br>
echo \"vmg\" >> .xbindkeysrc<br>
echo " m:0x0 + c:224" >> .xbindkeysrc<br>
echo "xbindkeys" >> .xsession<br>
<br>
After this sequence of commands, you will have to restart the XO. You<br>
will then be able to access the magnifying glass by pressing the F13<br>
key, the one to the right after the "volume up" key.<br>
