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
Or
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
info
here.
Now that kdebase is installed, we must change the /etc/rc.conf file to make it start KDE instead of fluxbox.
/etc/rc.conf
# nano -w /etc/rc.conf
At the end of the file, you will see the variable:
XSESSION="fluxbox"
Just change it to:
XSESSION="kde-3.5"
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
