bg_test(6)
NAME
bg_test - test the background mode of svgalib
SYNOPSIS
bg_test [linear]
DESCRIPTION
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
SVGALIB_DEFAULT_MODE.
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 sunsite.unc.edu at
/pub/Linux/libs/graphics and tsx-11.mit.edu at
/pub/linux/sources/libs which will most probably be mir
rored by a site close to you.
