I'll try it.

Does SDL needs his own modeline to run under X? (i'm newbie with linux...)
With both ALLEGRO and SDL 
I can set it up on my machine, but just on my machine using ALLEGRO from console (since my fbcon is set to 800x600)
I'd like to be able to make it work on a machine where i do not have root permissions.

Under X both SDL and ALLEGRO draw nothing but a black 800x600 window, and all i got is a "invalid pixmap" error.
The big problems under X are:
 - is possible to make my game run fullscreen? (ie: can X change width/height resolution and give the entire screen to my program?)
 - how do i control the keyboard? both ANSI C and ALLEGRO functions fail, am I forced to create an event handler?
 - how can i create a window and draw on it without reading the whole 0.5 Kg X manual? (ie: does exist a fast tutorial...)

The depth is not a real problem, since i should be able to convert it run-time.

Thank you all
