NAMEsavetextmode, textmode - save or restore the complete SVGA status for textmode.
DESCRIPTIONThese are simple scripts to save the SVGA register state when in textmode to the files /tmp/fontdata and /tmp/textregs or to restore it from these files.
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.

It is very likely that both are at least to some extent are due to Harm Hanemaayer <H.Hanemaayer@inter.nl.net>.
Occasionally this might be wrong. I hereby asked to be excused by the original author and will happily accept any additions or corrections to this first version of the svgalib manual.
