NAME

6       restoretextmode - save or restore the SVGA registers for textmode.
7

SYNOPSIS

9       restoretextmode {-r|-w} filename
10
11

DESCRIPTION

13       The state of the SVGA is written to or restored from filename using the
14       vga_gettextmoderegs(3) and vga_settextmoderegs(3) functions.
15
16       As of this writing this file is 385 bytes long but  this  might  change
17       with future versions.
18
19       Please do not fiddle with the contents of the file except when you know
20       what you do. It might even result in hardware damage. Because of  that,
21       you  should  think twice to make this command available to all users on
22       your system.
23
24       The purpose of this program is usually to recover from a  crashed  con‐
25       sole  due  to  an  svgalib,  Xfree or other program bug. First save the
26       state of the SVGA card when on a text console. After the crash  restore
27       this  state. The savetextmode(1) and textmode(1) script makes this pro‐
28       cedure very easy.
