● Prepare your PS3 for otheros using the instructions here
● Now turn on your PS3 with the Gentoo Install CD in the drive.
● Press Enter to boot the Gentoo kernel - It will boot and configure networking and other settings
automatically. Make sure you have a DHCP server on your network (Router or another PC which is
sharing the internet connection)
Installation starts now, with the livecd ~ # prompt

the "+10000M" to "+40000M")

The number of cylinders for this disk is set to 10239.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs

This will reboot your PS3. What it will do is force the installer to re-read the partition table. After it
reboots, you will be back at the kboot prompt and you can continue your installation from the next step.

# /etc/rc.conf: Global startup script configuration settings
# XSESSION is a new variable to control what window manager to start
# default with X if run with xdm, startx or xinit. The default behavior
# is to look in /etc/X11/Sessions/ and run the script in matching the
# value that XSESSION is set to. The support scripts are smart enough to
# look in all bin directories if it cant find a match in /etc/X11/Sessions/,
# so setting it to "enlightenment" can also work. This is basically used
# as a way for the system admin to configure a default system wide WM,
# allthough it will work if the user export XSESSION in his .bash_profile, etc.
# NOTE: 1) this behaviour is overridden when a ~/.xinitrc exists, and startx
# is called.
# 2) even if ~/.xsession exists, if XSESSION can be resolved, it will
# be executed rather than ~/.xsession, else KDM breaks ...
# Defaults depending on what you install currently include:
# Gnome - will start gnome-session
# kde-<version> - will start startkde (look in /etc/X11/Sessions/)
# Xsession - will start a terminal and a few other nice apps
Adding xdm to default run-level:
(chroot) livecd / # rc-update add xdm default

livecd mnt / # reboot
Remove the Gentoo CD from the PS3 when it is restarting. On the next boot, it will automatically boot
into the installed Gentoo.
Where to go from here
OK, so you've just finished on your PS3 and you're wondering what you can do with it. Firstly, here are a
few things you should do to make your Gentoo experience worthwhile.
What you should do after installation:
● Change the root password!
● Install applications, or enjoy Gentoo.
Edit /etc/make.conf to add GRP package repository
# nano -w /etc/make.conf
Edit the make.conf file and add the last line. Do not touch the rest of the sections above!
# These settings were set by the catalyst build script that automatically
# built this stage.
# Please consult /etc/make.conf.example for a more detailed example.
CFLAGS="-O2 -pipe -mtune=970 -mcpu=970 -mabi=altivec"
CXXFLAGS="-O2 -pipe -mtune=970 -mcpu=970 -mabi=altivec"
# This should not be changed unless you know exactly what you are doing. You
# should probably be using a different stage, instead.
Press Ctrl + X, then Y.
Since there are a few bugs in the current version of Portage, it is recommended that you use at least
portage-2.1.2-rc4-8 if you want to download pre-compiled binaries of applications (GRP Packages).
echo "sys-apps/portage ~ppc" >> /etc/portage/package.keywords
emerge -u portage
You can now emerge GRP packages using the -G / -g switch while installing them.
Note that if you did not use emerge --sync in the fist part of the tutorial, you should do it now.
Changing Desktop Environment/Window manager
The main difference between a Desktop Environment (DE) and a Window Manager (WM) is that while
DEs are a totally integrated environment with integrated applications, WMs are just a basic shell
which provide a dock to switch between different applications and an optional launcher to launch
This is something which varies from person to person. While some prefer minimal WMs, others would
rather have a full blown DE. It's just a matter of taste, and thankfully, with Gentoo, you can easily switch
to whatever you prefer. Here's a small list of the popular DEs/WMs: Desktop Environments:
● KDE - K Desktop Environment
● GNOME - GNU Object Model Environment
● Fluxbox (Installed by default)
While it would be possible to write how-tos for each of those and maybe more, I'm constrained by time
right now, so you'll have to install them on your own if you wish.
The magic word to install any application in Gentoo is emerge. Gentoo's package manager, known as
Portage, stores information for over 25,000 applications. At any point of time, if you want to install
an application, all you have to do is:
emerge <name of application>
So for example, if you want to install mplayer, all you have to type is
While this will install mplayer and all of its dependencies automatically, there are a few things which
you should do before actually installing it.
emerge -p <app>
What this will do is pretend to install the application. What it means is that it will show you the list
of dependencies it will install when you install that specific application. Go ahead, try emerge -p mplayer.
It will show you a list of dependencies for mplayer. Similarly, emerge -p openoffice will show you the list
of dependencies which it will install before installing OpenOffice itself.
emerge -v <app>
emerge -G/g <app>
One of the most useful switches for emerging applications on the PS3 is -G. What it does is look for
pre-compiled binaries of applications in the BINHOST which we specified in the /etc/make.conf file.
Since these binaries are compiled by others running Gentoo on the PS3, you can be sure that they will run
on the PS3. Last check of the BINHOST shows hundreds of pre-compiled applications.
emerge -pvG mplayer
emerge -pvg mplayer
This will a) pretend to install mplayer, b) show verbose output, c) check in the BINHOST if an mplayer
binary is available. Since it is available, just remove the -p switch to install the mplayer binary.
Unfortunately, not all applications have pre-compiled binaries. For those, you will have to do the
regular emerge -v <app> to install it.
For more emerge switches, just do man emerge in the command line, or here.
Changing the WM/DE
Alright, so now you guys know how to install applications. What if you want to install KDE, since you
prefer it above the minimalistic fluxbox. The process is just a couple of steps, and after a restart, you will
be looking at your new KDE desktop.
emerge -pvG kdebase
Since it is available as a binary,
emerge -vG kdebase
This will install the base of KDE 3.5. In Gentoo, KDE has been divided into small meta packages which
allow you to keep KDE lean and mean without installing all the useless bloat. You can check for more
Now that kdebase is installed, we must change the /etc/rc.conf file to make it start KDE instead of fluxbox.
# nano -w /etc/rc.conf
At the end of the file, you will see the variable:
Just change it to:
Then save and exit nano by pressing Ctrl + X -> Y. The next time you start your PS3 or restart xdm, you
will boot into KDE. Same goes for GNOME, or any other WM you would like to try. If you get confused
by what you're supposed to replace in the XSESSION variable, just check the contents of /etc/X11/Sessions
# ls /etc/X11/Sessions
Xsession fluxbox kde-3.5
Here, you can see that I can either put kde-3.5 or fluxbox as the XSESSION variable. Depending on
what WM/DE you install, you will see more sessions.
Until next time, have fun with Gentoo! :)
