[opensuse] Screensaver problem
Hello,I have the problem that the screensaver shows a black screen and not the screen which I have selected.Although,that black screen starts the right time I have set,after 1 minute.I tried the following and nothing works: 1)Uncheck the power control in peripherials->display->power management. 2)I played with xset.I tried xset s blank off.I tried sleep 1;xset s active and I had the same behaviour.I tried xset dpms force off and the screen turns off. 3)I reinstalled the kde screensavers packets from yast. 4)I uncheck the power management in right click->configure desktop->display->power control. Any help...Thanks in advance. ___________________________________________________________ Χρησιμοποιείτε Yahoo!; Βαρεθήκατε τα ενοχλητικά μηνύματα (spam); Το Yahoo!

Better yet, use the "black screen" screen saver. It will enable your monitor to power down after a while and not waste energy trying to draw graphics that nobody (except maybe your office neighbours) ever gets to see. I find it incredible what amount of energy gets wasted that way. Just my €0.02. -- Stefan Hundhammer <sh@suse.de> Penguin by conviction.

To my experience, the monitor powers down regardless of the screen saver (as defined in kpowersave, e.g.), at least with TFT displays. You could consider it a bug that the "blank screen" screensaver does not immediatly power down the display. I would support that view. ;-)

The energy waste is in the CPU/GPU still working on the graphics even after the screen has powered off. My guess would be very uneducated, but I don't think that's very substantial.

I fear it indeed is: http://www.behardware.com/articles/670-2/pc-s-actual-power-consumption.html 164 W idle vs. 207 W with load ( 43 W difference) 297 W idle vs. 472 W with load (175 W difference - yikes!) versus the ~30 W your average 19" TFT consumes. Agreed, with a screen saver you probably won't get your CPU or GPU to max energy consumption, but you can see that there is a significant difference between idle and load. And it's at least in the same league as your TFT's engergy consumption. CU -- Stefan Hundhammer <sh@suse.de> Penguin by conviction.

Some screensavers do indeed cause clockspeeds to increase - these are the most visually impressive ones of course :) 297 W is about 3 times the average power consumption of all systems in an efficient house! 2600 kWh per annum or £184 a year. I'm really surprised that GNU/Linux sits there actively hitting the disk every 30 seconds, let alone calculating screensavers. I'd have thought there'd be enough environmentalists among the OSS hordes to make it normal for the entire machine to shut down and just wake up periodically. Last time I tried with my 10.2 desktop, it wouldn't even resume from a suspend to disk when I told it to.

Display Power Management (DPMS) is separate from the screen saver.

What is that, now, a nickel? Times have changed.

Is there any possibility the DPMS can cause this behaviour?Can I disable it from the xorg.conf? ___________________________________________________________ Χρησιμοποιείτε Yahoo!; Βαρεθήκατε τα ενοχλητικά μηνύματα (spam); Το Yahoo!

I use KDE and I've never seen the DPMS settings in the KDE Control Center not work as they should. You don't say which desktop software you're using, but if it's KDE (and I would expect Gnome to have something comparable), you can select a screen saver and invoke it directly in testing mode from the Control Center (note that in this case, moving the mouse won't cancel the test, only a click or a keyboard will do that). This will allow you to verify that a given screen saver is working. But as Stefan and others point out, you should not disable DPMS for ordinary use. For kiosks, sure, but not for a system that's used as a desktop DPMS is much more important than a screen saver (especially for LCD displays). A final thing comes to mind: The power management software alters the way screen savers and DPMS work. I've never configured this stuff on my 10.0 system, so I don't know how it works there, but on 10.3, with the KDE power management tray application you can define and select modes (intended primarily for giving presentations) that suspend the screen saver and DPMS so your presentation is not interrupted. You might want to check out how that's set up and which regime is selected.

Yes, you can. Section "Monitor" ... Option "DPMS" That's to enable it, of course. And unless you really need your monitor to stay on, I would not disable it. In fact, I usually set the screensaver to run for two minutes, then power off the monitor using dpms. Maybe you have the settings wrong somewhere and off-mode kicks in at the same time as the screensaver. Or you are using screensavers that do not work - probably half or more of those available don't work on my computer (no 3d or accel, perhaps). - -- Cheers, Carlos E.

I unchecked again the box for the screensaver and check it immediately.And magically the screensaver appeared.It seems that with the default checked box on installation there is a problem. ___________________________________________________________ Χρησιμοποιείτε Yahoo!; Βαρεθήκατε τα ενοχλητικά μηνύματα (spam); Το Yahoo!
