restoretextmode(1) Svgalib User Manual restoretextmode(1)NAMErestoretextmode - save or restore the SVGA registers for textmode.
SYNOPSISrestoretextmode {-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 con‐
sole 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 pro‐
cedure very easy.
OPTIONS-w filename
write the SVGA state to the file filename.
-r filename
restore the SVGA state from the file filename.
