Screen Saver/ On-line Video Problem
Win10Pro x64 v.1809 Build 17763.557
Acer V3-731 laptop I watch a lot of tennis on-line since a lot of the good matches aren't televised on my cable channels. It used to be, if I had a video running full screen (Firefox 67.0.3 (64-bit)), my screensaver would not start up and interfere with it. Most of them use the Flash plug-in, and that also is the latest and greatest version. Recently (within the last 3 or 4 days), the screen saver starts up after the time set and continues to run until I move my mouse or press a key, just as it should. My desktop is one "update" behind (Build 17763.437), and the screen saver on it works as it should. Thinking the newer update (KB4503327) may be the problem (considering some of the other problems that have been posted about it), I uninstalled it. No change- screen saver still starts during videos. I could disable it, but that's not really fixing the problem. I seem to remember having this problem years (maybe even Windows versions) ago, but cannot find a fix for it. If anyone has had this problem and could provide a fix for it, I would be deeply appreciative. TIA!! -- SC Tom |

Or some policy change that inadvertently had this as a side effect. Paul |

If anyone has had this problem and could provide a fix for it, I would be deeply appreciative. TIA!! Does the screen saver show something, like the time or patterns? Or does it just show a blank (black) screen? If the latter, how do you know the screen saver activated (to blackout the screen) rather than a power option to unpower your monitor after awhile (that also blacks out the screen)? If the power plan is configured to turn off the monitor, check under the advanced settings and under the Multimedia settings. Configure the screen saver to have shorter expiration than for the monitor's power option which should be shorter than the expiration for sleep mode, if used. From what I know of Firefox and checked only, Firefox has no hooks to prevent triggering the screen saver. You said you are running Firefox in fullscreen mode. That'is not the same as maximizing its window. You sure you are using F11 to change Firefox into fullscreen mode instead of maximizing its window? I'm not sure the screen saver is checking for video traffic since that's between the video card and monitor. It does check for inactivity of the keyboard and mouse. Which screen saver are you using? One that came bundled in Windows or a 3rd party screen saver? I've read where users would report the screen saver would trigger (misbehave) despite seeing activity on the screen but the screen saver did not trigger (behave) when they switched to a different screen saver. Screen savers contain executable code. That's why malware can be distributed via .scr files. Same problem happen when you disable all extensions in Firefox, unload Firefox (to ensure all extensions are also unloaded from memory), reload Firefox, and retest? When Firefox is running fullscreened (not maximized) and playing a video stream, check the Event Viewer logs the next time the screen saver triggers during that test. You should see a 4802 event saying "The screen saver was invoked" and check who was the source of the invoke. https://docs.microsoft.com/en-us/win...ing/event-4802 Is the screen saver configured to require a password to unlock? Without it, the screen saver does not lock the Windows session. You could, for example, press run "%windir%\system32\mystify.scr" to immediately load that screen saver, but hitting any key will immediately unload it (unless you enabled the password option in the screen saver settings). Because .scr files are executable code, they can be called by anything to run. Have you check Task Scheduler to make sure no event was defined that runs the .scr program after some idle period, like using the "on idle" trigger for the event? Alas, Task Scheduler's GUI does have a nice search function to look for any event that has the specified string in the Actions definition (what to run) for the events. That's where SysInternals' AutoRuns and its filter can come in handy. I don't see Firefox controlling or blocking the screen saver. Maybe you started watching longer videos that play longer than the screen saver's idle timeout interval. |

It's always appreciated! OK, is there any way to figure out the history of your video card driver ? Do you have driver updates turned on ? When I do NVidia drivers here, I try to do just the driver part, and not the extras, and it still pulls in a ton of stuff it promised not to install. And installing the driver, always resets the time for the screensaver to cut in. So the driver install can be "slightly" intrusive. ******* You could compile your own copy of Firefox, in debug mode. Or compile under Visual Studio, so you could use Windbg. But the experience is not like the old days, in that the code paths are much too large and circuitous to make any sense. I tried that once for two hours and gave up. Single stepping just wasn't going to work. Setting breakpoints wasn't getting the job done any faster really. In Debug mode, it's supposed to do printf statements to a "console" that gets launched. Unfortunately, the quality of what is in the printf statements, is not sufficient to conclude much of anything. I was debugging printing at the time, and I might have got around five lines printed in the console. If you want an experiment to try, see if you can temporarily disable Electrolysis E10S, which turns a one task copy of Firefox, into five tasks. It does that, so that the "Flash" container or maybe even an HTML5 container, if it crashes, it doesn't take out the whole browser. But, you're supposed to be able to disable that, and go back to one task. The thing is, if you have five tasks, at some point if you have 200 tabs, the 200 tabs might be spread over 3 tasks. Having Flash in a container to play a movie, should use the same logic regardless, in terms of requesting continuous usage of the graphics display. Splitting Firefox into pieces like that, isn't supposed to change the characteristics. Paul |

Splitting Firefox into pieces like that, isn't supposed to change the characteristics. The graphics on this laptop is Intel® HD Graphics for 2nd Generation Intel® Processors. The CPU is a Pentium B950, which I assume also handles the graphics. https://ark.intel.com/content/www/us/en/ark/products/55627/intel-pentium-processor-b950-2m-cache-2-10-ghz.html It hasn't been updated in quite some time; not even sure if there's anything newer than what I have already. Yeah, not too sure if it's worth all the trouble of compiling my own Firefox, but thanks anyhow :-) -- SC Tom |

Almost all tennis matches are longer than that :-) Thanks for the tips! -- SC Tom |

In the dialog that pops up, click in the field that says All Event IDs, which will clear that text. Enter your desired Event ID and click OK. To clear the search and start over, click the Clear button at the lower right corner of that dialog, or in the Actions pane click on Clear Filter. (In the Actions pane, Clear Filter is only available if you actually have a filter set.) That's a basic search. To get more granular, you can adjust the "Any Time" field and/or the Event level or any of the other things on that dialog. Everything you do will restrict the output that much more. To get started on your first search, enter an Event ID that you can actually see in the unfiltered event list, just to get a feel for how it all works. |
