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
|
||
|
|
.BR savetextmode (1)
|
||
|
|
and
|
||
|
|
.BR textmode (1)
|
||
|
|
script makes this procedure very easy.
