I'm running KDE 2.1 and I've turned on the Energy Saving settings in the Energy section of Power Control within the KDE Control Center. However, the settings have no effect; even when I set the interval to 1 minute, nothing happens after a minute. I know of several other places where there are parameters to set: 1. In the kernel (where ACPI is for some reason grayed out in "make xconfig" no matter what I do) 2. In the BIOS, which has settings for suspending and also for turning off the hard drives after a specified interval 3. In the X settings, though I don't know exactly where I did get from the kernel docs that there are two competing standards, APM and ACPI. Where can I learn about how all of this works? And does anyone know what I might need to done that I haven't done to make the KDE settings work? Paul
