How to disable screensaver when watching online movie on web?

Hi , I want to know , When watching online film on web , How to disable a screensaver . I know where to find screensaver settings , but there is only options for start screensaver after unactivity . Thanks

Easy way

is in our repo…

Thank you , I am beginner .

You can outright disable the automatic screensaver and session lock, though that may be overkill…

Checkout the xset command.

Xfce power management has a Presentation Mode to disable screensaver or suspend settings

Left click Power Manager plugin in system tray to turn it on

or use this command to toggle Presentation Mode on/off

xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/presentation-mode -T

Right click and selecting Power Manager Preferences has an option to show an additional indicator when Presentation Mode is on

If you, like me, don’t care about the screen being changed/dimmed/switched off after some time:
I have disabled the screensaver
as well as the display power management
just for that same reason.

I don’t need a screensaver anyway
and the display power management is what gets in the way here.

You reach it directly via:
LANG=C xfce4-power-manager-settings --> the "Display" tab
switch it off for both “On Battery” and “Plugged in”

But maybe the caffeine solution is better for you - but you may have to remember to activate it each time
(it says it will activate itself when something is put into fullscreen, so it should be a good tool for this purpose, watching movies …)
