       bg_test - test the background mode of svgalib

       bg_test [linear]

       Tests  the  enhanced  support  of  recent svgalibs to draw
       while switched to the background. Draws a  small  centered
       white box then waits until you switch to another vc. Draws
       some outer box frame around it while background, which you
       can  see  when you switch back to it. For obvious reasons,
       your version  of  svgalib  must  have  BACKGROUND  support
       enabled  (which  is the default as of this writing).  When
       finished, press any key to end bg_test.

       The demo uses a G320x200x256 mode or the one you set  with

       If  you  specify  the  linear  parameter the demo will use
       vgagl(7) and  vga_setlinearaddressing(3)  to  test  linear
       mode in background.

       This  demo  is  part  of  svgalib  and can be found in the
       demos/ subdirectory of the original svgalib  distribution.
       However,  it  is  not  installed in the system by default,
       s.t. it is unclear where you can find it if  your  svgalib
       was  installed by some linux distribution. Even then, when
       you have the demo on your system, you probably won't  have
       the sources s.t. it is only of limited use for you.

       In case of any such problem, simply get an svgalib distri-
       bution from the net. You even don't need  to  install  it.
       Just  make  in  the demos/ subdirecty. As of this writing,
       svgalib-1.2.12.tar.gz is the latest  version  and  can  be
       retrieved     by     ftp     from    at
       /pub/Linux/libs/graphics     and     at
       /pub/linux/sources/libs  which  will most probably be mir-
       rored by a site close to you.

       This manual page was edited by Michael Weller <eowmob@exp->.  The  exact  source  of the referenced
       demo as well as of the original documentation is  unknown.

       It  is  very  likely that both are at least to some extent
       are due to Harm Hanemaayer <>.

       Occasionally this might be wrong. I  hereby  asked  to  be
       excused by the original author and will happily accept any
       additions or corrections to  this  first  version  of  the
       svgalib manual.
