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_settextmoderegs(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 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 procedure very easy.

OPTIONS

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

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