keytest(6)

NAME
keytest - tests the svgalib raw keyboard functions

SYNOPSIS
keytest

DESCRIPTION
A program to test the low-level keyboard interface. This uses basic VGA functionality (or an svga mode you specify). Works only in 256 color modes. Cursor keys or keypad <1>, <2>, <3>, <4>, <5>, <6>, <7>, <8>, and <9> move the cursor. Keypad <0> or <Enter> changes color. <Q> or <Ctrl>-C quits. (autoquit after 60 seconds). Note that the svgalib diagonal <7>, <9>, <1>, and <3> keypad keys emulation is flawed in that it emulates the vertical/horizontal keys. If one of these is pressed too, it's release confuses svgalib. The top pixel line shows a blue pixel for each key which is reported to be pressed. You can set a videomode to use by setting the environment variable GSVGAMODE to a number (see vgatest for a list) or a string like G0x1x2 where you replace 0 with desired x resolution, 1 with the desired y rez, and 2 with the desired number of colors (2, 16, 256, 32K, 64K, 16M, 16M4). Again, only certain choices are available, see vgatest for a list. In case nothing is selected, G320x200x256 is choosen. 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.
