Thread: Power Management settings are not saved

  1. #1

    Default Power Management settings are not saved

    Hello everybody!

    I've got openSUSE 11.4 64 bit system with stable 2.6.38 kernel and KDE 4.6.3. Problem is that when I want to change some settings in the power management (like brightness, screen energy saving time-off, display dim), they doesn't seem to save, even after the X restart and full reboot. It's seems like screen energy saving is set permanently for couple of minutes, don't matter what time do i set, it just discards my settings, even they are correctly viewed in the gui. Any suggestion to get it working?

    Thank you!

    Hello!

    I have already tested to tweak some settings in the screen saver menu, turn it off, increase the time etc. but it doesn't make any diffrence for the power management settings - they are still not saved while changing them.

    Thanks

    My screen is turning off after ca. 15 minutes. I want to change it to 7-8 minutes and turn on the Display Dim function after 5 minutes, just to save some energy. Unfortunatly those settings are not respected after I change them. They simply doesn't work. Any other settings in the power profile doesn't work either like the Display Brightness. I think that something could got corrupted while upgrading KDE to 4.6.3 or after the kernel update.

    Thank you!

    I don't know if this will help, but it is worth the try.

    Logout.

    Use CTRL-ALT-F1 to get a terminal screen. Login there.
    cd /var/tmp

    You will find a kdecache directory that you own, and probably with your login id as part of the name.
    rm -rf kdecache-whatever-appears-here

    Then logout, use CTRL-ALT-F7 to get back to the GUI screen, and login again.

    That will cause KDE to regenerate its cached settings. I have seen those get corrupt. In any case, rebuilding them causes no problems other than a slightly slower login while they are being rebuilt.

    Hello nrickert, and thank you for your tips!

    Unfortunatly clearing the kdecache didn't fix my issue.

    You could try running the following command to see if the screen blanker comes from the kernel.

    Code:
    xset s noblank -dpms
    We could make a bash script of this to run each time you start openSUSE if this does any good.

    Hello and sorry for not answering faster. Had a quite busy days.
    I've tried to run this command: xset s noblank -dpms
    I don't know if it's working or not, well there was no output in the terminal. Could it possibly fix the issue with power management settings?

    Today I've tried to install newest KDE from another repository, thought that the diffrent build could probably fix it. Unfortunatly - those settings still aren't working.
    By the way, could you explain deeper the diffrence of following KDE repositories?:

    Upstream release aka. KR46 (KDE SC 4.6)
    Core packages: Index of /repositories/KDE:/Release:/46/openSUSE_11.4
    Extra: Index of /repositories/KDE:/Extra/KDE_Release_46_openSUSE_11.4

    Factory aka. KDF (KDE SC 4.6)
    Core packages: Index of /repositories/KDE:/Distro:/Factory/openSUSE_11.4
    Extra: Index of /repositories/KDE:/Extra/openSUSE_11.4_KDE_Distro_Factory

    The Upstream KDE repository is one with 'clean' KDE, community supported and the Factory KDE is with openSUSE optimalizations/tweaks? Do I understood it correctly? I should avoid to mix them up together, am I right? At the moment, I am using the Factory repository only

    In general, unless you really feel adventurous and lucky, I would stick with Upstream as shown above. You can get into trouble using Factory as it could be unstable. Lots of people use it and test it all of the time, but if your more into running other applications besides desktops, I would stay away from factory myself. Of course, you can stick with the original distribution version as well, that came with openSUSE.
