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 /etc/vga/fontdata and
       /etc/vga/textregs ($HOME/.vga/fontdata and $HOME/.vga/textregs if directory /etc/vga is not  writeable)  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   running   program   with   <Ctrl>-C,
       <Ctrl>-<Alt>-<Backspace>,  or whatever applies. 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 understand.


FILES
       /etc/vga/fontdata or $HOME/.vga/fontdata
       /etc/vga/textregs or $HOME/.vga/textregs
