savetextmode(1)		      Svgalib User Manual	       savetextmode(1)

NAME
       savetextmode,  textmode	- save or restore the complete SVGA status for
       textmode.

SYNOPSIS
       savetextmode
       textmode

DESCRIPTION
       These are simple	scripts	to  save  the  SVGA  register  state  when  in
       textmode	 to the	files /tmp/fontdata and	/tmp/textregs or to restore it
       from these files.

       The actual utilities used are restorefont(1),  restoretextmode(1),  and
       restorepalette(1).

       The  purpose  of	 these	scripts	 program  is usually to	recover	from a
       crashed console due to an svgalib, Xfree	or other program bug.

       You do this by being a smart guy	and running savetextmode  right	 after
       booting	of your	machine, prior to any problems.	Then, in case the SVGA
       state is	hosed and you sit in front of  a  blank	 or  useless  console,
       change  VC (maybe login)	to get to a shell. Or exist the	currently run-
       ning program with <Ctrl>-C, <Ctrl>-<Alt>-<Backspace>, or	 whatever  ap-
       plies.  Once you	got a shell, run textmode and it will hopefully	render
       your console useable again.

       To make it clear: You do	all this while not  seeing  anything  on  your
       console	screen,	you enter this information blindly or after logging in
       from a network. Also, if	the keyboard is	left in	raw mode, nothing  can
       really  help you	as you cannot enter anything which a shell will	under-
       stand.

FILES
       /tmp/fontdata
       /tmp/textregs

       original	documentation is unknown.

       It is very likely that both are at least	to some	extent are due to Harm

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