vgatest - makes basic tests on any svgalib graphics mode
The testimage consists of a sequence of crosses (in different colors, if the mode support has different colors) in the top left corner.
Below you see three color bars red, green, blue with increasing intensity from left to right. Depending on the capabilities of the mode they are more or less jumpy (or smooth for true color).
In case of modes with 32K or more colors, six squares will appear on top of that, each showing some different smooth color shades
It also shows some details from vga_getmodeinfo(3).
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 sunsite.unc.edu at /pub/Linux/libs/graphics and tsx-11.mit.edu 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@example.com>. 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 <H.Hanemaayer@inter.nl.net>.
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.
