NAME

6       bg_test - test the background mode of svgalib
7

SYNOPSIS

9       bg_test [linear]
10
11

DESCRIPTION

13       Tests the enhanced support of recent svgalibs to draw while switched to
14       the background. Draws a small centered white box then waits  until  you
15       switch  to another vc. Draws some outer box frame around it while back‐
16       ground, which you can see when you switch back to it. For obvious  rea‐
17       sons,  your  version  of  svgalib  must have BACKGROUND support enabled
18       (which is the default as of this writing).  When  finished,  press  any
19       key to end bg_test.
20
21       The   demo   uses   a  G320x200x256  mode  or  the  one  you  set  with
22       SVGALIB_DEFAULT_MODE.
23
24       If you specify the linear parameter the  demo  will  use  vgagl(7)  and
25       vga_setlinearaddressing(3) to test linear mode in background.
26
27       This  demo  is part of svgalib and can be found in the demos/ subdirec‐
28       tory of the original svgalib distribution. However, it is not installed
29       in  the  system by default, s.t. it is unclear where you can find it if
30       your svgalib was installed by some linux distribution. Even then,  when
31       you  have  the demo on your system, you probably won't have the sources
32       s.t. it is only of limited use for you.
33
34       In case of any such problem, simply get an  svgalib  distribution  from
35       the  net.  You  even  don't need to install it. Just make in the demos/
36       subdirecty. As of this writing,  svgalib-1.2.12.tar.gz  is  the  latest
37       version   and   can   be  retrieved  by  ftp  from  sunsite.unc.edu  at
38       /pub/Linux/libs/graphics and tsx-11.mit.edu at  /pub/linux/sources/libs
39       which will most probably be mirrored by a site close to you.
