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
