I also know that when watching videos on YouTube (in firefox, using whatever the default backend player) the dpms settings do *not* get disabled, and the screen may go into standby in the middle of an interesting scene. :-) I wouldn't know about other video players (I use only mplayer), but I guess that they should implement this feature also (if they're worth their wit anyway). Finally, one can control this behavior manually, using "xset -dpms" and "xset +dpms" (man xset, and look for dpms-related options). The dpms is also being turned off automatically (AFAIK) when working in "presentation" mode in okular (i.e. when your document is displayed in fullscreen) --- you don't want the screen with your important slides to go into standby in the middle of a lecture you're giving. ;-) Again, I don't know about other document viewers out there. > well, i disable all that "power savings" for the screen which don't > save anything measureable these days, when i want my screen locked or > powered off i do that on my own It certainly is measurable, and turning off the screen can save considerable amount of battery power, in an idling laptop situation (people can be forgetful and undisciplined to turn it off while taking an unexpected phone-call, or when children yell for attention, or some such --- not having to babysit your laptop can be very convenient). In a desktop situation it usually doesn't make much sense. Maybe in a rare situation of power-grid failure, when the UPS batteries take over the load of the servers and terminals in your datacenter --- shutting off idle monitors can make all the difference between staying online through the crisis versus having to reboot the whole infrastructure. But of course that's not a very common situation (it happened to me only once). > when not it's on for good reasons like sit in front of the TV and due > go to the kitchen for a fresh beer take a quick look if something > interesting happended in my mailclient or messenger Just put "xset -dpms" somewhere in your login (or bootup) scripts, and live happily everafter. :-) Best, :-) Marko _______________________________________________ kde mailing list kde@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/kde New to KDE4? - get help from http://userbase.kde.org
