RedHat 6.2
I recompiled the kernel and updated to 2.4.14 kernel without AMP support.
and I think that I shouldn't have any power management package installed.
(anyone can tell me what are the packages is for power managemant?)
someone told me that you can have monitor goes blank without power manager 
(do 'setterm -blank ...'). I am afraid that there is some thing similar 
shell commands for setting harddrive, printer... idle for a certain amount 
of time.
and I don't know the command to disable the setting. for example,
I recompiled the kernel and updated to 2.4.14 kernel without AMP support. 
and no screen saver package installe. I don't use X windows, onlt text mode. 
my monitor still goes blank after a while idle. now I know I control by 
setterm command, but  for other devices (harddrive...), how do I know what's 
going, where to set if there such features?
