Thread: Auto Adjusting Brightness

  1. #1

    Default Auto Adjusting Brightness

    KDE 4.8

    For some odd reason, sometimes my screen auto adjust the brightness to one before the last notch. When I turn it back up I'll sometimes bring it right back down again.

    Tell us more. openSUSE version, 32 or 64 bit, computer model, make, monitor model and make if not a laptop, video chipset if known. Can I assume you speak of the brightness control in the Power Management section of the KDE Configure Desktop function? You can open up terminal and run the following command for more on your graphic setup:

    Code:
    sudo /usr/sbin/hwinfo --gfxcard
    Thank You,

    Correct. I use my function keys to turn it back up and I can just see it go back down sometimes. Real weird, this just started happening.

    KDE is up to KDE 4.8.3. Have you upgraded to 4.8.3 or did it happen after you did an upgrade to 4.8.3 by chance? I do wonder if it might be a KDE bug, though the driver is part of the kernel and you can improve the kernel version up to 3.4 if you wanted to do so, but I am not sure just what the issue might be.

    Sorry you are correct I'm using KDE 4.8.3.

    *edit*

    Sometimes it goes down without me even touching it.

    Would you consider a newer kernel, where the Intel Driver is located? SAKC will keep your old kernel in place and it will still be selectable if you don't like the newest one.

    Does your laptop has a light sensor ? maybe it actually started to work as it should have been from the start with the newest KDE version.

    Yes it does, I actually considered that by just covering it and seeing what happens but cant' really tell. I'd still like to upgrade my kernel. Is there a special way to go about it using openSUSE or can I just use the method found at Linux Newbie Guide: Kernel Upgrade? I downloaded both the full source and patch.

    Use James advice or if like me You're to lazy to compile use the stable kernel repository :
    Index of /repositories/Kernel:/stable/standard

    I'm currently using kernel 3.3.1 which once was in that repository and that resolved my wireless problems which were present in the standard openSUSE 11.4 kernel:
