fix132x43(1)                  Svgalib User Manual                 fix132x43(1)

NAME
       fix132x43 - fix problems with certain (132 column) graphics modes dump
       the state of the card as the svgalib chipset driver sees it.

SYNOPSIS
       fix132x43 options

DESCRIPTION
       This program tries to fix problems with extended textmodes on some
       cards. The problem is that for 132x43 textmode, some BIOS's set the
       vertical display end register to 349 (350), instead of 343 (344 = 3 * 8
       scanlines). Because in Linux textmode video memory is usually filled
       with old text that has already scrolled away (this includes the area
       below the 43rd textmode line, which changes when the console scrolls),
       the top half of a constantly changing irrelevant text line is visible
       at the bottom of the screen, which is very annoying.

       This program sets the VGA Vertical Display End register to the proper
       value.

       This problem is at least present in the BIOS of most Cirrus Logic 542x
       based cards, and some WD90C03x based cards.

       The LINES environment variable is used to detect 43 or 44 line
       consoles.

OPTIONS
       You have to specify exactly one of the following options:

       -f     Fix problem of annoying changing line of text at bottom of
              screen.

       -v     Switch to 9 line characters (400 line frame, 70 Hz).

       -w     Switch to 11 line characters (480 line frame, 60 Hz).

              fix132x43 does not usually provide this option but it can be
              enabled in the source of fix132x43.

       -r     Switch to 8 line characters again (350 line frame, 70 Hz).

       This utility is part of svgalib and can be found in the utils/
       subdirectory of the original svgalib distribution. However, it is not
       installed by default, s.t. it is unclear where you can find it if your
       svgalib was install linux distribution.

       In case of any such problem, simply get an svgalib distribution from
       the net. You don't need to install it. Just make in the utils/
       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.
