Greg -
Thanks for your suggestion, but as it happens my problem is solved. It turned out to be my stupidity - I thought I had the screensaver set but I hadn't and it was defaulting to a blank screen.
There is one other place that is involved in turning the screen off, and it bugged me greatly until I started digging everywhere. I use a blank screensaver by preference, with a 30 minute setting. I was still getting screen off after 10.
Turning off ACPI in the BIOS didn't work (Linux seems to be famous for ignoring BIOS settings and using system capabilities instead -- which is nice if you must fool the BIOS because of some bug, not necessarily nice always).
KDE by default uses DPMS, and that setting is nowhere near the one for the screensaver. Open KControl, click on Peripherals/Display, then select the "Power control" tab. There you can deselect power management, or if you choose to use it, configure separate timings for standby, suspend and power off. The defaults are 10, 20 and 30 minutes, respectively, which is where your 10 minute interval is coming from.
Arun Khan also suggested running "xset -dpms" which does the same thing. The xset command is probably worth looking at, because it performs a lot of tasks that KDE has scattered all over the place (and that is annoying to say the least).
My monitor has a built-in power down after 5 minutes of inactivity on the screen. So, I have to set my screen savers to fire up after 4 minutes; otherwise, the monitor powers down (it doesn't turn off, it just shuts off the signal to the screen). Greg Wallace
