Thread: How to do this

  1. #1

    Default How to do this

    How to turn off screen saver? I watch movies frequently on my computer and I just hate when it pop up each few minutes. Second, I'm also programer, is there any way that when I turn off my pc and turn it on agian next time it save me where I was? for example if I was in codeblocks that it start from there? I heard that is possible on some linux distros.

    Which Desktop Environment are you using?

    In KDE it's "Configure Desktop"(aka. systemsettings)->Display and Monitor->Screen Locker.
    And also check the PowerManagement settings.

    But how are you watching movies?
    AFAIK all of the available movie players inhibit the screen saver/locker anyway. Maybe you have to turn that on in the player's settings though.

    Second, I'm also programer, is there any way that when I turn off my pc and turn it on agian next time it save me where I was? for example if I was in codeblocks that it start from there? I heard that is possible on some linux distros.
    You mean, suspend/hibernate?
    Of course that's possible.

    How you would do it depends on your Desktop Environment again.
    In KDE you have a Suspend and Hibernate entry in the K-Menu ("Leave"), or on the logout dialog press and hold the "Shutdown" button longer to get a submenu with Suspend and Hibernate.

    And running "systemctl hibernate" or "systemctl suspend" in a terminal window should work in any case.

    OTOH, KDE by default saves which applications are running when you logout and starts them again when you login. You can configure that in "Configure Desktop"->"Startup and Shutdown"->"Session Management".
    Other Desktops might have a similar feature (or not), so again, please tell what Desktop Environment you are using.

    Like wolf323 says, do not let your potential helpers guess about the most basic information you could provide us at the top of your question. Which version of openSUSE and which desktop.

    It seem that is KDE. I'm 99% sure btw where the hell I can check that out? It's really amazing how using different linux distros is like openining new world.

    /etc/sysconfig/windowmanager maybe? (I suppose you're using Auto-Login)
    It should be clear from how your desktop looks like as well. So maybe post a screenshot.

    What did you select during installation, or which LiveDVD did you download?

    Oh, and btw, you can use different desktop environments on every Linux distro I suppose. It's not that you're limited to KDE on openSUSE, and f.e. GNOME on some other distro.

    Dim screen darkens the display after some time to save energy. This mostly works on laptops only.

    So did turning off the screen energy saving "solve" your problem?

    And again, what player application are you using?

    If Kaffeine will show the movies you want to see, problem solved. Kaffeine sends a dummy click every so often to fool the screen saver.

    Right, just like MPlayer (and Xine of course, as Kaffeine is just another frontend to libxine).
    And VLC inhibits the screen saver/power management while playing.

    Depending on the player there might be a configuration setting to enable/disable this.

    If you're playing online streams using flash-player, you're out of luck though. Even on Windows 7...

    I saw this trick first in xine. If I remember correctly, they simply
    tell the keyboard to toggle the upper-case key status and let for a
    split second. I once noticed it blinking, so I searched for the reason.

    The problem in Linux is that there is not an API call to disable the
    screensaver, common for all desktops, so applications resolve to tricks.

    In KDE 4, I think you can quickly change to a different profile, however
    it is called. But I don't remember the trick, I do not use the KDE full
    desktop.
