Is there some Linux distribution/settings that allow me to "simulate" a console? That is: 1) When the O.S. initializes, nothing is shown to the screen (or just a personalized message, like "...wait please...") 2) The desktop is not shown (or at least the icones/menus/etc are not shown) 3) The game initializes automatically. Thanks in advance

With fiddling with the kernel, you can tell it to use a bootsplash rather than the standard kernel messages that appear. This way you can provide a logo (or just a blank image) and that should sufficiently obscure the guts of the kernel.

The other two questions can be accomplished using rc-scripts for your runlevel. Just grab the rcX.d file/folder for whatever runlevel you are at, and modify the scripts to launch whatever you want.

You can also customize X through a variety of configuration files to start up a different window manager, possibly a stripped-down twm or custom-written manager that does what you need.

Thank you very much, Ravuya.
