FAQ about Linux Legacy GGI:
Q:My mouse does not work with GGI why?
A:GGI can't detect your mouse type, so
  you must set your mouse type correctly,
  use the environment variable GGI_INPUT
  for example:
  export 'GGI_INPUT=(linux-mouse:msc)'
                                 ^^^mouse type MouseSystems, like gpm
  
  refer to inputs.txt
  or GGI:degas/lib/libgii/doc/inputs.txt
  
Q:How to use DGA?
A:use GGI_DISPLAY to control the display type,
  for example:
  export GGI_DISPLAY=dga
                     ^^^fbdev Xlib X glide svgalib vgagl...etc
		     
  refer to targets.txt
  or GGI:degas/lib/libggi/doc/targets.txt
  
Q:llggidoom said: "No video modes available!"?
A:like DOS Legacy, GGI Legacy must use 8bits or 15bits(-highcolor)
  you are in X or your svgalib/glide/fbdev... don't have these modes,
  this will be added in new GGI Legacy, but it will be best(faster)
  to run Legacy in a 8bits or 15bits mode.
