OLPC where to go development advice.

[Carol Farlow Lerche]

Here is a good current Ubuntu (Intrepid 8.10) to try with installation
instructions, together with a page that collects the answers to a lot of
questions that others have come up with:

http://www.olpcnews.com/forum/index.php?topic=40

To install it, you will have to buy an SD card (I just put an 8GB Transcend
SD in each of my 5 XOs so they would dual boot this and they all work
beautifully).

In particular, there is an explanation for how to bind all the keys to
something rational in the regular Ubuntu Linux desktop.

Many people have used USB keyboards successfully with the XO, though I have
not personally tried this.  I routinely use my USB mouse with my XOs.

Regards,

Carol Lerche
