Usage

textmode
Overview
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.
