To start X on the PS3 console, log in then type startx on the command line. If you encounter an error:

    (EE) Unable to locate/open config file

then you need to first run Xautoconfig (as root) to create the config file /etc/X11/xorg.conf.

    % login root
    % Xautoconfig
    Wrote /etc/X11/xorg.conf

Now try startx again and test that X is working properly by running emacs. If you encounter errors of the kind

    Undefined color: "black"

then edit /etc/X11/xorg.conf and remove the .txt extension in rgb.txt that appears on this line

    RgbPath "/usr/share/X11/rgb.txt"

or comment out the line to force the X server to use the compiled in path. Now restart X, and retest.
