|
||
|
|
.SH NAME
|
||
|
|
savetextmode, textmode \- save or restore the complete SVGA status for textmode.
|
||
|
|
.SH SYNOPSIS
|
||
|
|
|
||
|
|
.B savetextmode
|
||
|
|
.br
|
||
|
|
.B textmode
|
||
|
|
|
||
|
|
.SH DESCRIPTION
|
||
|
|
These are simple scripts to save the SVGA register state when in textmode to the
|
||
|
|
files
|
||
|
|
.IR /tmp/fontdata " and " /tmp/textregs
|
||
|
|
or to restore it from these files.
|
||
|
|
|
||
|
|
The actual utilities used are
|
||
|
|
.BR restorefont (1),
|
||
|
|
.BR restoretextmode "(1), and "
|
||
|
|
.BR 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
|
||
|
|
.B savetextmode
|
||
|
|
right after booting of your machine,
|
||
|
|
.B 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
|
||
|
|
.BR <Ctrl>-C ", "
|
||
|
|
.BR <Ctrl>-<Alt>-<Backspace> ,
|
||
|
|
or whatever applies. Once you got a shell, run
|
||
|
|
.B 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.
