“Previously, I had attempted to install Ubuntu on this
laptop, but I ran into numerous errors during the installation, and
frankly, it wasn’t worth the trouble at the time. Soon after the
release of Ubuntu 9.04, I checked the PPC download page and saw a
download link available. I downloaded it and burned the image to a
CD with the hopes of installing it on my laptop. Upon booting to
the CD, I was very surprised to see a live CD session typical with
all other Ubuntu editions. After noticing that most of the hardware
was working, I began the install.“(In past times I did not get a live CD session. I had to
attempt the install from a very basic UI, which at first didn’t
detect my keyboard, and later, after detecting the keyboard, the
CD-Rom drive was not detected. The message read, “No common CD-ROM
drive was detected.” The solution is found here.)“To my surprise, the install completed in good time and Ubuntu
was asking me if I wanted to reboot or continue using the live CD
session. Of course, I rebooted. Shortly after, the computer came to
the log-in prompt without a hitch, and after typing in my username
and password, I was staring at my new Ubuntu desktop on my
PowerBook G4. I was ready to begin.”
