is it possible?

Explicitly I'm looking for Lucid Lynx (10.4x) and kernel 2.6.34
(because of singletouch/multitouch LCD screen support)

mmh.. I should run and get an armor while waiting for responses..

but thanks in advance for what to come..

Fair enough, dear friend. But I must say I stand with Amigo1...

Sure, it's possible somehow (probably with some restrictions). But creating a Ubuntu install CD needs time and that is usually the limiting factor.

@Amigo1

I think it's possible using the Debian kernel instead of the Ubuntu kernel... so not really Ubuntu but the same GNOME setup etc...

@Geri

Is this correct, I'm sure the Ubuntu kernel doesn't support the AOne. Infact Ubuntu is stopping or has stopped support for many Apple PPC devices...

Yes it is. In fact with inspiration from a few people I've been working on it myself.

I'd like to run the Lynx as well. And a later kernel would be nice, especially as later releases tend to rely on it. But 2.6.18 is the latest stable we have. Geri was working on a 2.6.31-32 but it isn't ready yet. There is a 2.6.32 in testing but AFAIK it isn't up to the standard of 2.6.18 yet.

So it depends on what release is compatible with our kernel.

The A1 uses a custom kernel, as does the Sam. However the Pegasos looks like it has it easy here as it has it's own boot scripts on the official CD!

But regarding Ubuntu on PPC we have these in the ports secton:

There's no Linux distribution that supports the A1. So it's "just" a matter of compiling a kernel with an adequate kernel config and modifying an installer to use this kernel.

A small group of Ubuntu developers still works on PowerPC support (but inofficially).

I've found a Jaunty Jackalope PPC install, would it be possible to then dist-upgrade to LL?

anyway, the kernel is what i'm looking for; mainly for touch screen support.
I've read through some ubuntu pages, and the basic support is in 2.6.32 too, but it's missing the patches to USB-HID (as far as I understood).
Would it be possible for you to compile the patches into the 2.6.32?

I have no working linux ATM, but this is what I've researched so far..

There should also be an Ubuntu 10.04 PPC install image, so I don't think it is necessary to upgrade from an older version. I'm just afraid that we run into huge problems with the new radeon graphics drivers that come with the latest Ubuntu release. They don't work well on my A1.

If the patches apply cleanly, then yes.

Ouch, that sounds quite complicated. Do they have a simple diff/patch for kernel v2.6.32?

I have not had any reply still. As soon as I get, I will post it or forward it to you.

Okay, thanks for the info.

BTW: which multitouch device do you use?
