How do I stop screen from blanking out during a movie ?

Hello,

Just converted over from Mandriva to SUSE - install of 12.1 64-bit KDE was very easy!!

When I am watching a movie or streaming video, the screen will blank out after about 10 to 15 minutes. I have disabled the screen saver (set a long time to enable screen saver), so it is not that. I am thinking it a power saving feature that needs to be turned off. I am sure that this is a common problem, but was not able to find the solution with a search (probably not using the right terminology). How do I proceed?? I gather in Mandriva I needed to edit the /etc/X11/xorg.conf file, but switched over before trying that.

Thanks – Roger

There’s probably a setting somewhere, but what I tend to do is just run:

xset -dpms

And that turns off the power saving.

you are correct, it is a power saving feature, and it is common…

in the KDE desktop (mine is a little older than yours, so the names may
be off some) go Personal Settings - Configure Desktop > Hardware > Power
Management

on the left two selections Global settings, where you decide what
profile will be in force for each of the power settings there…

and, on the left Power Profiles where you decide what each profile does…

so, if you on the global page set Performance profile for when the
machine is on main power/plugged into the electricity grid…then go to
the Power Profiles and adjust the Performance Profile which you will see
came default set to blank the screen at 10 minutes, or so…so you need
to (for example) set it to dim the display after 109 minutes, and switch
the screen off at 111, and then suspend the session at 120, when you
wake up your machine will be snoozing also…UNLESS while watching the
movie you see the screen dim OR go blank and wiggle the mouse . . .

lots of opportunities to tune it to do exactly what you want…

don’t overlook the “Help” button in the lower left corner…

Disable screensaver too

Thanks for all of the input - sounds pretty straightforward (now that I know where everything is…).

I haven’t tried this with 12.1.

When using opensuse 11.4, I did:

Personal settings → Startup and Shutdown → Service Manager

and their I unchecked the box for “Power Management” and also click the “Stop” button to stop the running power management applet.

Once I had finished with the movie, I rechecked the box for Power Management and restarted it.

Stopping the power manager might be excessive, I think it does other things, like controlling
cpu power usage :-?
