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 filename using the vga_gettextmoderegs(3) and vga_set-
       textmoderegs(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
       hardware  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 pro-
       gram 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 procedure very easy.


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

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