Every time I leave my computer for a few minutes, the screen goes blank. How can I fix this?
If you have a screen saver running, you may want to turn it off. In text mode, the kernel will "screen-save" your system unless you use:
setterm -powersave off -blank 0
Otherwise, if you hear disk drives speed up or other sounds, this is probably APM kicking in. Disable APM from starting at boot time by logging in as root and typing ntsysv. Then deselect APM. Leave ntsysv and you will need to reboot the machine. (This is one of the few services that you have to restart the system, as APM is so deeply connected to the kernel that a full reset is needed.)
