restoretextmode(1)     Svgalib User Manual     restoretextmode(1)

NAME
       restoretextmode  -  save or restore the SVGA registers for
       textmode.

SYNOPSIS
       restoretextmode {-r|-w} filename

DESCRIPTION
       The state of the SVGA is written to or restored from file-
       name  using the vga_gettextmoderegs(3) and vga_settextmod-
       eregs(3) functions.

       As of this writing this file is 385 bytes  long  but  this
       might change with future versions.

       Please  do not fiddle with the contents of the file except
       when you know what you do. It might even result  in  hard-
       ware  damage.  Because  of that, you should think twice to
       make this command available to all users on your system.

       The purpose of this program is usually to recover  from  a
       crashed  console due to an svgalib, Xfree or other program
       bug. First save the state of the SVGA card when on a  text
       console.   After   the   crash  restore  this  state.  The
       savetextmode(1) and textmode(1) script makes  this  proce-
       dure very easy.

OPTIONS
       -w filename
              write the SVGA state to the file filename.

       -r filename
              restore the SVGA state from the file filename.
