OpenSuse 10.0 when originally installed used to go to screensaver after 4 minutes and then a little later it put the monitor in standby. Suddenly it now still goes to screensaver but never goes to the standby stage. Where was/is this controlled? I found KRandRTray but never had to use this before!?

have a look in YAST Bootloader Options, and see if APM is turned to OFF in Other Boot-options (APM=OFF)
If YES, delete this option and reboot.

No, APM was not listed. I recently installed the latest Nvidia binary. It seems to be working well but could that have caused this?

What about your ACPI?

No, ACPI was not listed either.

Does the monitor shut down under Windoze?
Do you have ICQ?

Yes, the monitor still shuts down under Windoze. (That desktop looked strange to me because I have not seen it for several months!)
No, I do not have ICQ

What about BIOS?

Nothing has been changed in BIOS and as we just discovered the function still works in Windoze so only Linux has changed.

I think I just found it. A few days ago I had used SAX2 to temporarily change my monitor selection from the monitor it had detected to a VESA monitor so I could do some testing. When I changed it back, the "Activate DPMS" box was not checked and I failed to notice it. I just went back and checked it and I suspect that will solve the problem.

Followup: Yes, that solved the problem! Thanks Soren!

I'm having the same problem, but my Activate DPMS box is checked. The controls for this used to be in the screensaver settings on the gnome control panel, but they are not there now; also, there are no options for the individual screen savers like their used to be. Anyone know where the setting for monitor standby are now?

I think I figured out what is going on. The xscreensaver was not being used, instead the default is gnomescreensaver. If you go to the Gnome configuration editor, under the apps/gnome-screensaver folder there are options for dpms_enabled, dpms_off, dpms_standby, and dpms_suspend. Setting those solved the problem. An alternate solution was to disable the gnome-screensaver, and go back to using xscreensaver. Running xscreensaver-demo brings up the configuration box that I remember from older versions of gnome. The options for the individual screensavers are there along with standby & suspend options. You can also just edit the .xscreensaver file in your home directory.
