I'd like to be able to switch the monitors on a number of
our computers into standby mode from a software program
running on a virtual console; and wakeup either when a key is
pressed or when the program has new information to display.
I can probably manage to control blank screen savers but I
would prefer to power down the displays to standby modes.
The machines are those small size 'kitchen computer' VIA
based cubes (almost). The monitors are LCD displays.
Are there ioctls to help with this?
How do I go about it?
All ideas welcomed.
