What is your video card?

Unless you absolutely want to test a specific driver, you
should *always* use GFX_AUTODETECT. Certainly if you want to
distribute a program you should do this. It means that other
people who have different hardware can still run your program,
despite having a nonexistant or buggy VESA BIOS, if there's
another Allegro driver they can use (e.g. a dedicated hardware
driver, or VBE/AF).
In any case, if you choose to autodetect then Allegro will try
all of its drivers with your card, and maybe one of them will
work while VESA did not.
If that fails, get hold of UniVBE (Scitech Display Doctor),
which will provide a better VESA implementation for your card.
