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
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.

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
