iBook G4 trackpad no longer working

I have an iBook G4. The trackpad used to work in earlier versions of Ubuntu, but I just finished upgrading and it no longer works in Ubuntu 11.10.

alex@orientalibombus:~$ sudo trackpad show
no trackpad !

I checked /var/log/Xorg.0.log and searched for ADB mouse and this seemed to be the relevant part:

There are sections regarding my Logitech mouse, the ADB keyboard, powerbutton, etc. Can you spot anything suspicious?

Not tried 11.10 so don't know if there is a problem, but have you tried editing your xorg.conf file? I don't like an overcomplicated one as I think it leads to more problems if things change in an update. What happens if you remove your input device section?

Thanks for the answer. I'll check that. In the mean time I noticed that the problem is much less severe than I thought. If the laptop boots without the external Logitech mouse connected, the trackpad will work. Weird. :)

I just did a fresh install of 11.10 on my ibook G4 and the trackpad worked out of the box.

I checked your log against mine and they are identical. At least in the section you posted.
So nothing suspicious there.

Also no problems with my external mouse. Just a normal 3 button and a wheel one. Weird indeed.
What kind of mouse is it. Anything fancy?

jumil, welcome to the forum! Did you use a live cd to install 11.10 and when did you download the image? Did you have any problems with the install?

The 11.10 mini iso I downloaded did not recognize the ibooks hard drive during install. I don't know if that has been fixed by now.

So I used the 11.04 mini iso to install a command line system and ran the upgrade from there.
Upgrading 11.04 on my desktop had not properly switched from GDM to LightDM. And since I was primarily after trying how LightDM would perform on the iBook I wanted to do a clean install.

After upgrading the base system to 11.10 I installed Ubuntu via tasksel.

kensanata, since you seem to be using Ubuntu 11.10 on an iBookG4 can you please tell me if you are experiencing the same problems I am?

I have described theese in another thread
http://ubuntuforums.org/showthread.php?t=1863407

Also what Display manager are yu currently using? Did the transition from GDM to LighDM happen for you?

I will try switching my system to GDM later to see if my problems might be connected to that.
