How to disable screen and powersaving during Video Playback

Solution 1

I suggest using a program called Caffeine.

Once you have installed Caffeine, and disabled the screensaver, any videos that you watch will not be interrupted by the power management.

Caffeine

I have this on my system and it works perfectly.

Caffeine Preferences

Disabled Screensaver

Solution 2

There is an app called caffeine that solves this for you:

sudo add-apt-repository ppa:caffeine-developers/ppa
sudo apt-get update
sudo apt-get install caffeine

Caffeine's launchpad page

    So I have noticed, even going back to Ubuntu 11.xx releases the screen for some ungodly reason dims itself while a video is playing. Iv'e even observed the thing go into sleep mode with the audio still going till it shut itself off. Here we are at 13.10 and this is STILL the case >:{ (same with Mint15 and Fedora)

    It doesn't matter if I'm using VLC or watching youtube on Firefox or Chrome. The darn computer for some reason thinks nothing is going on!

    I could go into how this never happened on Windows nor Mac, but I'll just say this; Why isn't this something built in by DEFAULT!!!

    Has anyone a WORKING(ie the famous one I've run into don't work/refer to sites or scripts that no longer exist) system level tweak/script/fix for this nonsense?!(before I throw my already dying laptop out the window)

    It does stop the screen from going into Power Saving Mode [Going Black].

    Not on my system. Screen goes black (as set in Brightness & Lock ) even when Activate for Flash video is checked.

    Make sure that Turn Screen Off When Inactive For: is set to Never.

    Then what is the point of Caffeine if I disable the screensaver ?

    I'm running Lubuntu 20.10, Groovy Gorilla. Caffeine doesn't seem to work. How can I access the preferences dialog box? It does not appear on the context menu. I'd like to add VLC to the list of programs that automatically activate caffeine. It seems that the only use of caffeine indicator is to manually turn caffeine on and off. Caffeine by itself should function just fine if the settings are well set. Is this correct?
