Using the console screen protection feature
VGA consoles can be set up to blank after a certain number of seconds
to protect the screen from excessive wear. The kernel parameter
TBLNK controls the VGA console screen protection feature.
By default, screen blanking is not performed:
to enable this feature,
log in as root and use the
command or the Hardware/Kernel Manager
``Configuration tools'' in the Performance Guide.
Select category 9, ``TTY and console configuration''
the value of TBLNK to the number of seconds that the system
should wait before blanking the screen. Then relink the kernel
as described in
``Relinking the kernel'' in the SCO OpenServer Handbook.
