Hello
I have many many questions but starting with them would be rude - so I
will first introduce myself :-)
My name is Guylhem Aznar, I am a medical resident doing a PhD in
computer science, working on computer support for a written form of
sign languages. (for a good introduction on the topic

As explained before, I started playing with the DCON (displaying test

The results are interesting. For example, a black and white mode will

Hello,
Been there, done that, for different devices - mostly PDAs.
First you *must* check the specs : optimism won't get you far if the
pins have different fonctions (like they have been swapped) or require
some minor adaptations. Get the reference sheets for each device, read
them and

Some time ago I did post a mail about sign language work.
I just wanted to let interested parties know that I have finished
redacting my thesis, and that I am trying to have someone work on an
implementation for at least proper fingerspelling support.

Hello
Today I had a little problem with my OLPC B4.
Long story short - windows XP support announcement, although
controversial, was good news for my project acceptance (and more
importantly, financing)- which really did surprise me, but whatever.
So I wanted to resume my development efforts,

I was wondering if I could return my motherboard to get a current
mass-production one without the documented hardware bugs : I fear I
may not be able to perform all the fixes required

support.
I guess the current
Hello
I wouldn't necessarily want another machine - just a motherboard from
say a machine that has been returned with a broken screen, or
whatever, would be fine
A fully working XO would be best used for someone who hasn't one yet IMHO.
Anyway, I'll drop a message
Thanks

Hello
A suggestion for similar problems, which I experienced in the past for
other hardware.
The /var tree is mostly used for logs and caches - stuff that could be
discarded at reboot. And usually, there's a lof ot them (see with du

There are some important subdirs that however should be

Hello
Whenever a jack is plugged in, the audio is routed to the jack instead
of the main speakers. It may not always be desirable (ex: wakeup
clock)
Did try to tweak alsa settings, but I couldn't change that.
Is there a way to override it?
Thanks

After my (mostly) successfull B4 to C2 motherboard surgery, I am left
with a working B4 motherboard that I would like to use for various
tests purposes, including kernel stability tests and perfs

It is a bare motherboard- no display, no keyboard, no battery. Just a

This redesign may not be desirable however, because it would introduce
a serious difference in the OLPC user interfaces - yet I think it
should be mentionned.

Hello
A boards had CN18 to select the output between VGA and LCD.
It is no longer presnt on the boards. How can it be implemented?
(strip wire, software, ... ?)
For the VGA plug, I'd also be interested in a P/N to get one from
mouser, mousekey etc.
Thanks

UBIFS? Say coreboot , or even a bios with grub,
anything will do!
If there's no security, if there's little functionality, not field
upgrades etc, it will just be fine as long as it can boot any quicker.
I just can't keep the boot delays currently experienced with jffs2
