[SDL] The Basic Linux Basic

[DARKGuy .]

Agreed with Paulo.

In my own personal opinion by experience:

You don't need Framebuffer unless your game runs in it, which isn't X but
say... when you can make the terminal have background images, or
bootscreens... that's what Framebuffer is in a practical way: a video mode
without X (isn't hardware-accelerated and not very optimized for graphics
speed as X is).

DRI, as I see it, is a way to get direct access to the video card's hardware
(and thus, get awesome hardware acceleration, in 2D too though it's mostly
used and required for 3D), so that's a good option and works wonderfully for
newer video cards.

VESA is an old MS-DOS mode that was used for high-res graphics. It wasn't
very fast with alpha blending and all that flashy stuff that we're used to
see in newer 2D games, but it allowed to run stuff at 1280x1024 (and even
higher) fast enough with a CPU that supported it back in the time. Right
now, I'd see VESA as a compatible video mode for those old video cards which
can't or don't support DRI, have bad drivers, or stuff like that. It would
be a good idea to include it as the most compatible (but slower, maybe)
option.
