       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 distribution 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 mirrored by a site close to you.

       This manual page was edited by Michael Weller <[email protected]>. 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 <[email protected]>.

       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.
