How do u change the power settings from the command line? My Arch server seems to go into standby if u don't give it any activity after about 10 minutes. As a result, you can't access any of the pages on it when it's in standby.
You can turn off acpi and apm completly by adding acpi=off apm=off in grub/lilo settings (kernel parameters). Or just search for acpi with google or forums.
