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.

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.

57 Occasionally this might be wrong. I hereby asked to be excused by the
