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.
