NAME¶
restoretextmode - save or restore the SVGA registers for textmode.
SYNOPSIS¶
restoretextmode {-r|-w} filename
DESCRIPTION¶
The state of the SVGA is written to or restored from
filename using the
vga_gettextmoderegs(3) and
vga_settextmoderegs(3) functions.
As of this writing this file is 385 bytes long but this might change with future
versions.
Please do not fiddle with the contents of the file except when you know what you
do. It might even result in hardware damage. Because of that, you should think
twice to make this command available to all users on your system.
The purpose of this program is usually to recover from a crashed console due to
an svgalib, Xfree or other program bug. First save the state of the SVGA card
when on a text console. After the crash restore this state. The
savetextmode(1) and
textmode(1) script makes this procedure very
easy.
