restoretextmode(1) Svgalib User Manual restoretextmode(1) 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 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.
