I have installed Kubuntu 5.04 on a PowerBook G4. Neither the trackpad, nor a USB mouse appear to be working. After a bit of research I'm at the following:
Trackpad: it seems that Apple changed the trackpad supplier when they introduced a new version of powerbooks in January 2005, and it's not the "standard" trackpad that's supported by linux anymore. There's a driver out there - (google for "PowerBook/touchpad/driver") and I have not yet tried it out.

USB mouse: during boot I get the following message:
PCI: Probing PCI hardware
PCI: Cannot allocate resource region 0 of device 0001:10:18.0
PCI: Cannot allocate resource region 0 of device 0001:10:19.0
Apple USB OHCI 0001:10:18.0 disabled by firmware
Apple USB OHCI 0001:10:19.0 disabled by firmware

I've searched around for a while, but did not find what exactly "cannot allocate resource region" means, or what to do to fix it.

Also, with the Kubuntu installation the sound doesn't seem to work, but I'm not too worried about that, since it worked when I tried FC4 - I'll figure that one out once I have some kind of pointing device up and running.

So, if anybody can explain what precisely the PCI errors mean, or have any suggestions on how to fix them, please post!

Sorry, I can't answer your question, but why did you replace Mac OS X with Kubuntu? I mean, Kubuntu is a great distro, and I love it, but why would you want to replace Mac OS X on an actual Apple laptop!? Especially on a new one, when Kubuntu could work just as well on a normal (Intel/AMD) laptop?

Anyway, have you tried plugging a PS/2 mouse in to see if that works? Maybe if you do that you might be able to click around in the Control Centre and change your mouse configuration. Hope this works,

I ran the live CD on a Powerbook and I found if I plugged in a USB mouse after the system was fully booted it worked. For the previous poster - there is no PS2 connection on a Powerbook.
