Screen blanks while watching video. Leap 15.5 KDE
I installed 15.5 a couple of weeks ago and one annoyance is the screen will blank after a few minutes while watching a video, unless I move the mouse or press a key occasionally. Is there any way to stop that behaviour, while a video is playing? tnx jk

That appears to stop it from blanking during a video. It also appears to stop it from blanking when idle.
Make a file in /etc/X11/xorg.conf.d/ containing: Section "Monitor" Identifier "DefaultMonitor" Option "DPMS" "off" EndSection I think that Option "BlankTime" "120" has similar effect. I use the latter instead of the former on my main PC, but I also set screen power saving in personal settings to 120min. I normally don't watch videos of as much as 120m on a PC. I go lay in front of the TV for that, but I use the same settings for the PC connected to my TV. My Samsung PC screen stays on no matter what for 120m after last mouse or KB input, unless I flip off its nice mechanical power switch on its rear. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.

You could. It's no longer provided in new TW installs. I would have thought it would have been gone by now in Leap too. Maybe in 15.6 it will be. That file as it currently exists does nothing. It's all comments, so you would need all the lines from my prior reply, or to uncomment those that are equivalent. The identifier can be anything other than null. Unlike Carlos' recommendation, this should affect any and every DE you might log into, should you ever log into something besides Plasma to watch your videos. -- Evolution as taught in public schools is, like religion, based on faith, not based on science.

That prevents my system from booting to a desktop.

But of course, you are inhibiting it from blanking *ever*. I have a similar problem in a laptop with VLC on Leap 15.4 and XFCE Settings → advanced settings Settings → Video → Disable screensaver [X] Yet it blanks. What I had to do was to increase the desktop blanking time to 60 minutes while on mains power, which is the maximum on XFCE. Likely I will press a key during the hour, to pause the movie or repeat a section. I might try xine instead to see if it works. -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)
I'm using "firefox" on KDE. And "firefox" seems to always block power savings while playing media. If your browser doesn't do that, you can click on the power icon in the tray, and manually block power savings. If you are not using KDE, then this won't help.

I have that on my ThinkPad, but this is a desktop system. On my desktop, it shows my UPS, though I just found a battery setting that may be useful. I just noticed that when I click on that setting, a battery appears on my tray. I'll have to see what happens next time I watch a video.

while I do not believe that energy app has anything to do with your screen blanking while viewing a video past the screensaver, it does contain configuration for screen blanking which you apparently did not find. perhaps you need to be somewhat more inquisitive in what setting are available for your system (besides networking). did you bother to look for settings in firefox to stop screen blanking while viewing a video? or try google or duckduckdo or ... if you find these things on your own, you will be more likely to remember them the next time, and there will be a next time. -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet oftc

1) I've never had to worry about that before. 2) I did look around and didn't see anything appropriate. I have noticed some other changes, such as duplicate web sites not showing as such. In 15.4, if I made a 2nd connection to the same thing, the browser would say so. There are other changes that I'm not thrilled with.

maybe not about *this particular instance*, but you have many others as you have testified here.
2) I did look around and didn't see anything appropriate.
apparently you spent miniminal effort. the first hit I get on google searching for "firefox screen blanking while viewing a videw" had some very good information.

quite possible a difference in configuration or a new configuration. but, "1) I've never had to worry about that before." no pain, no gain, and quick to forget!. -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet oftc

It is up to the application you use to watch the video to stop the desktop from blanking. It may be configurable. I know that, for example, xine-ui emulated the keyboard being used, by touching one of the LEDs on and off. Uppercase-shift or something. -- Cheers / Saludos, Carlos E. R.

I normally use Firefox and have done so for years. I've noticed a few things seem to be missing with 15.5.
I never use Firefox to watch a video. Unless you are talking of youtube or similar online sites. Sometimes, Firefox actually calls a plugin to display the video, or calls a detached player. That plugin will have settings. -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)

Yeah, mostly YouTube. I don't recall any such plugin or settings. It just worked. There is a setting someone else mentioned on the "battery", which I've set. I'll have to see what happens next time I watch a video that lasts longer than a few minutes.

That battery setting didn't do anything for this problem, but it fixed another, where the screen wouldn't go black when the computer was idle.

It's the Firefox that came with 15.5. I did a fresh install, retaining only /home from 15.4. It was fine with 15.4, but not 15.5.
and "/home" did not contain .mozilla/ which contains settings for firefox. AND YOU KNOW THIS. -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet oftc

As a workaround, you could try "Enable Presentation Mode" on the Display Configuration menu. You'd have to turn it on and then off again when you were done, but at least you could then watch a video without interruption.

Yeah, I already saw that and decided against it.
