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).
Darryl - I'm sure your analysis of the problem is correct. When I reset my screen saver I also disabled power management at the same time and then my problem disappeared. Now I'm not actually as stupid as I seem. I *had* previously gone to power management and disabled it. It didn't correct the problem. Then I enabled power management but set all the settings to "disabled" in the hope that might work better. It didn't. This was how it was when I reset the screen saver - so I tried disabling power management globally again at the same time. One or the other worked. I think you're right and it was power management to blame, but I'm sure it didn't work correctly first time for me. Thanks for your interest and help - and thanks to all the other people who gave suggestions. Best wishes to you all. - Ken
