ERROR: Firmware file "b43-open/ucodes5.fw" not found
Installation impossible ?
Allez, pour rendre utiles mes galères passées :
Installation Ubuntu 12,04 sur mac powerpc G4
Brancher internet avec un câble sur le G4
Bouter sur cd d'installation dont l'image est disponible ici :
http://cdimage.ubuntu.com/releases/12.04/release/ubuntu-12.04-desktop-powerpc.iso
puis, avant que le noyau linux se lance entrer : live b43.blacklist=yes
suivre l'installation
Au redémarrage et après le boot entrer : Linux b43.blacklist=yes
ça marche !
faire marcher la wifi : installer firmware-b43-installer
le son :

Why do I have no sound?
Sound should work 'out of the box' on the vast majority of machines. However, if you can't hear any sound then first check your channel volumes and mute settings. You need to check more than just your master volume, for example the volume of the PCM channel maybe set to zero (set it to around 80%). Use alsamixer (from a terminal) or gnome-alsamixer to do this (there is a nice screencast of these here). The letter m toggles mute in alsamixer.
If this doesn't solve the problem then you may have to investigate the kernel modules used by your sound card. Check the various system logs or use the command lsmod to see what is being loaded. Older Macs should use snd-powermac. Newer Macs use snd-aoa, snd-aoa-fabric-layout, snd-aoa-soundbus, and snd-aoa-i2sbus, plus one of snd-aoa-codec-onyx, snd-aoa-codec-tas and snd-aoa-codec-toonie. Seehttp://johannes.sipsolutions.net/Projects/snd-aoa and the unofficial alsa wiki for greater detail.
Occasionally, the automatic setup does not work correctly and you may have to modprobe some modules. To automatically 'modprobe' a module on startup you should include it in the /etc/modules file. Open the file using the command "sudo nano /etc/modules" and add either "snd-powermac" or "snd-aoa" etc on a new line.
Recent versions of Ubuntu have inherited a bug from Debian, where snd-aoa modules are incorrectly blacklisted. If this is the case, the easiest thing to do is to delete the /etc/modprobe.d/blacklist.local.conf file that is generated by the installer (sudo rm /etc/modprobe.d/blacklist.local.conf ). Also, delete any references to sound modules in the /etc/modules file and see if it works without them.
To get sound working on a Powermac G4 Digital Audio (which should use snd-powermac) you may have to blacklist some modules. Seehttp://lists.debian.org/debian-powerpc/2011/04/msg00063.html for additional advice. Open/create the file /etc/modprobe.d/blacklist.local.conf (the command is "sudo nano /etc/modprobe.d/blacklist.local.conf") and add
blacklist snd-aoa
blacklist snd-aoa-fabric-layout
blacklist snd-aoa-soundbus
blacklist snd-aoa-i2sbus
blacklist snd-aoa-codec-tas
If you find your master sound is always muted when you start the computer and you have pulse audio installed (Ubuntu, Kubuntu, Xubuntu) then try unmuting the system sounds in the sound settings.
En gros et en ce qui me concerne, la carte son est blacklistée,
Il faut donc supprimer /etc/modprobe.d/blacklist.local.conf et les lignes qui concernent la carte son dans /etc/modules
Pour moi ça marche bien
ajoutons un environnement xfce, wmbatppc pour la batterie, et des applications légère comme midori, gthumb, sylpheed...
et youpi !
Au plaisir
