Laptop Screen Slowly darkens when watching a movie

Hi

Every time I watch a movie (online or though a movie player) the screen slowly darkens. But it doesn’t do this when I am watching a movie though Totem. Is there any way I can disable this. I can’t open the video URL (e.g. youtube video) though totem as it requires a codec.

You did not say what desktop that you use. For KDE, go to menu / Personnel Settings / Hardware / Power Management / Profiles and uncheck the top three options that have to do with your display for the profile you normally use. Also, make sure that auto screen brightness is turned off in your BIOS settings. For instance, Dell laptops have such a BIOS setting with a photocell controlling brightness by default.

Thank You,

Hi,

Are you with GNOME or KDE.

Sorry

To prevent the screen to turn off, install this :

zypper in gnome-applets-inhibit-powersave

and add the applet to the panel. You can now disable screen turning off easily when you wacth a movie. :wink:

I have discovered it was the screen saver. I disabled it and the video plays fine. I tried to put that command in terminal but it requires root Privileges. How do I access the console as root?

You can add the pre-command **sudo **in front of a command you wish to run as root, then enter the root password and the following command will be ran as root. Using sudo does not append the paths for commands not in your user path. For instance, to use the command fdisk with sudo, I must append the path to fdisk as in:

sudo /sbin/fdisk -l

The second way is to use su - to become root with root’s paths as in the command sequence:

su -
password:
fdisk -l
exit

The exit command then relinquishes root authority. Always be careful using root as it can allow you to do things you might not really want to do.

Thank You,

When I went to install it it says:

GLib-GIO:ERROR:gdbusconnection.c:2279:initable_init: assertion failed: (connection->initialization_error == NULL)

But still goes to the screensaver.
