In my previous column, 'Snow
Leopard' and the Death of PowerPC Support, I had a small look at
what Linux has to offer owners of old Macs that won't be supported by
new applications and Mac OS versions - and now it's turned into a
column.
I will give you a look at 1) if Linux can replace Mac OS X, 2) if
it's good enough for everyday use, and 3) compatibility and
stability.
I will use two everyday "Snow Leopard unsupported" Macs: a 1 GHz Titanium PowerBook
G4 and a classic low-end Mac, the iBook G3 (Clamshell).
I'm a huge fan of Ubuntu and Kubuntu, having used these distros
successfully on a number of Celeron PCs a year ago, so those are what
I'm going to look into.
Ubuntu 'Hardy Heron' on the PowerBook
This PowerBook G4 has a 1 GHz G4 processor, 512 MB of RAM, and a 40
GB hard drive. I will use Ubuntu 8.04 "Hardy Heron". (Ubuntu 6.10 LTS
"Edgy Eft" was the last version to officially support PowerPC, but
luckily it is still community supported.)
Booting from the CD takes you to the Yaboot bootloader. Just
press Enter, and the system will load. It might take a while, so
this is a good time to get some coffee.
When it's finally booted, you are greeted with a clean, nice desktop
containing nothing but an installer icon and an Examples
folder.
So far so good. Hardy Heron looks really nice. I've never used it
before, and I must say the GUI is a huge improvement from "Feisty Fawn"
(Ubuntu 7.x).
Opening the installer lets you answer a few questions, like "Where
are you located?", "Which time zone are you in?", and "What keyboard
layout do you prefer?". Then we're at the part where you erase your
hard drive.
I took a deep breath and quickly pressed Yes, removing
everything on my hard drive.
The system will now install. This is another good time to get some
coffee - 15 to 30 minutes later, your system should be installed.
Now for the review. Ubuntu 8.04 is freakin' awesome. It has a great
GUI, is very speedy, and comes with great software like Firefox and Abiword. The experience is totally
different from what I went through with Xubuntu on my Digital Audio Power Mac.
And compatibility? Well, there are not a lot of games for Ubuntu,
but that's okay. I do my gaming on a Vista laptop and my eMac. DivX
files are easily viewed with VLC Media
Player, and writing is done in Abiword. You browse the web in
Firefox, and you check your email in Thunderbird.
I love Ubuntu 8.04. I will not reinstall Mac OS X on this
PowerBook, leaving it with Ubuntu. I have an old Pentium III laptop
somewhere with Windows 2000 installed, I think that laptop would be a
lot sweeter with Ubuntu as well.
Conclusion: Ubuntu 8.04 is a worthy replacement for Mac OS X. It has
everything you need preinstalled, just like OS X, and it "just
works", similar to OS X.

Kubuntu 5.04 'Hoary Hedgehog' on the iBook
This iBook is equipped with a 466 MHz PowerPC G3 processor and 192
MB of RAM. Due to the low specifications, I figured Kubuntu, Ubuntu based on the KDE environment rather than Ubuntu's standard
Gnome environment, would be
great.
It boots and installs just
like Ubuntu, so I don't think we need to dig deep into this part. Let's
move on to the operating system itself.
Even with just 192 MB of RAM, Kubuntu runs great on the iBook. Those
of you who like the Windows GUI will most certainly enjoy Kubuntu. It
uses KDE, which has a start menu and desktop similar to that of
Windows.
You browse the Web in Konqueror, which is a great browser
(Apple's Safari browser is based on it), and you can use Kmail to check your email.
Kubuntu 5.04 is a great choice for G3 systems with low memory and
for those who are new to Linux. It is very easy to use, and the KDE
environment is kinda lightweight, so it's definitely no Vista
Ultimate-style hog.
Conclusion: Kubuntu is a great choice for low-end Macs and it also
has a very user-friendly interface. However, it lacks the style and
class of Ubuntu's Gnome.

Well, I hope this column helps you somewhat into the world of PPC
Linux. It is a good choice, and distros like Ubuntu 8.04 are a fine
example of how free operating systems can be really good. I'm still not
a huge fan of Xubuntu; the window manager/GUI (Xfce) feels very pale
and ugly and it's quite slow on a DP 533. However it remains a good
choice for old Wintels and perhaps some G5s that are low on RAM.
It won't replace Mac OS X overall; but on the PowerBook, it's just
too great to pass up.
