S10-3 Screen Brightness Linux work around

I am running Mint 9 and Ubuntu 10.04 on my S10-3. Very happy with the platform overall, but as many have found their screen brightness keys do not work. My web research indicates that the latest kernels will have a fix, but that probably won't be commonly available until the end of 2010. In the mean time I have implemented the following to get easy control over the brightness. It's not perfect but it gets the job done. Create three launchers on the desktop with one each of the following commands. Select the screen brightness icon and title each launcher as Low, Med , High Low> sudo setpci -s 00:02.0 f4.b=35 Med> sudo setpci -s 00:02.0 f4.b=55 High> sudo setpci -s 00:02.0 f4.b=75 credit to: https://bugs.launchpad.net/ubuntu/+source/linux/+b​ug/538256 http://lgallardo.com/en/2010/08/31/control-del-bri​llo-de-lenovo-s10-3-video-gma-3150-on-linux/

Maybe this topic is outdated, but probably this info will be useful for S10 linux users: official ubuntu kernel 2.26.35-25+ works good. This means new Ubuntu, Mint 10 and similar forks works good with brightness adjustment with no additional tools or tweaks.

  • [SOLVED] ASUS Screen Brightness Not Working

    I have been trying for a few hours to get my screen brightness to work properly. I'm on an ASUS Zenbook Prime UX31A with kernel 3.9.6-1. I'm using efibootmgr to boot.
    According to the wiki page and numerous posts, I need to use the acpi_osi="!Windows 2012" boot parameter. When I set it using efibootmgr, the keyboard backlight keys work (Fn+F[34]), but the screen brightness keys (Fn+F[56]) do not work. I have tried the following in efibootmgr:
    # efibootmgr -c -w -d /dev/sda -p 1 -L "Arch Linux" -l '\EFI\arch\vmlinuz-arch.efi' -u initrd=EFI/arch/initramfs-arch.img root=UUID=d0b32080-84f0-4c6b-933b-f62b880afc09 ro rootfstype=ext4 efi_no_storage_paranoia elevator=noop acpi_osi=Linux add_efi_memmap
    # efibootmgr -c -w -d /dev/sda -p 1 -L "Arch Linux" -l '\EFI\arch\vmlinuz-arch.efi' -u initrd=EFI/arch/initramfs-arch.img root=UUID=d0b32080-84f0-4c6b-933b-f62b880afc09 ro rootfstype=ext4 efi_no_storage_paranoia elevator=noop acpi_osi=intel add_efi_memmap
    # efibootmgr -c -w -d /dev/sda -p 1 -L "Arch Linux" -l '\EFI\arch\vmlinuz-arch.efi' -u initrd=EFI/arch/initramfs-arch.img root=UUID=d0b32080-84f0-4c6b-933b-f62b880afc09 ro rootfstype=ext4 efi_no_storage_paranoia elevator=noop acpi_osi= add_efi_memmap
    and a few others. The particularly peculiar thing is when I use a UEFI shell to boot with my script:
    echo -on
    \EFI\arch\vmlinuz-arch.efi root=UUID=d0b32080-84f0-4c6b-933b-f62b880afc09 ro rootfstype=ext4 add_efi_memmap efi_no_storage_paranoia initrd=EFI/arch/initramfs-arch.img elevator=noop acpi_osi="!Windows 2012"
    it works fine (both keyboard backlight and screen brightness).
    What am I doing wrong? My hunch is that I'm doing something wrong with the formatting of acpi_osi="!Windows 2012" but I'm pretty sure I've tried every combination of different quotes and escaping different things. It's also worth nothing that the "!" gets interpreted by bash in some of these permutations making efibootmgr not actually run.

    Because you are entering it in a shell, you need to escape some of the things in the acpi_osi="!Windows 2012" string.  So for example, the double quotes are intended to be entered exactly as is in the resulting efibootmgr entry, so these should be esacped since they would otherwise have a special meaning in the command line.  The same is true for the exclamation point.  So I think you would have to do:
    efibootmgr -c -w -d /dev/sda -p 1 -L "Arch Linux" -l '\EFI\arch\vmlinuz-arch.efi' -u "initrd=/EFI/arch/initramfs-arch.img root=UUID=d0b32080-84f0-4c6b-933b-f62b880afc09 ro rootfstype=ext4 efi_no_storage_paranoia elevator=noop acpi_osi=\"\!Windows 2012\" add_efi_memmap"
    BTW, this is just a copy/paste of one of the entries above (slightly fixed).  I added a '/' to your initrd entry, as it is supposed to be an absolute path, not a relative one.
    Edit: I too started out with a direct efibootmgr entry when getting to know UEFI.  But I think that a better solution is to use a boot manager.  I like gummiboot, but I also keep rEFInd set up as well.  By doing this, if you ever want to chane something on your kernel command line, you can just edit the config before reboot.  But I think that were it is really useful is if you need to modify the kernel command line before you boot, as it is not possible with a direct efibootmgr entry.  If you want to make it seem seamless, just set the timeout to zero in efibootmgr, and then if you want to get to the menu, you just hold the spacebar while booting. 
    The reason I wanted to use a direct efibootmgr entry was because I thought it would be faster.  But because gummiboot and systemd will actually give you the time it takes to boot which includes the time in the firmware (POST) as well as the time it takes to get through the boot manager, I have actually found that my system takes a whole 14ms from the end of POST to starting to load the kernel.
    Edit2: BTW, I also quoted the entire srting of arguments on the kernel command line, which it need in order to be fed to the '-u' option as a single string.
    I'm afraid that still doesn't work. I've tried similar things and tried that specifically.  In case you're wondering, the command you listed gives me the following output:
    $ sudo efibootmgr -v
    BootCurrent: 0000
    Timeout: 2 seconds
    BootOrder: 0000

    I also tried putting the -u argument in single quotes so that I don't have to escape the double quotes or the !. That also didn't work. Thanks for your suggestions, I'd be happy to try more, I've tried a lot already to no avail :-(

  • Screen brightness not working after updating windows 10

  • [XP on late 2008 Unibody] No option to auto-adjust screen brightness

    Why does there seem to be no option to automatically adjust the screen brightness in the Boot Camp control panel on Windows XP SP3? I remember having run Windows Vista on the same machine and automatic screen brightness would work in Vista.

    Hi,
    Open windows Control Panel and open Power Options.  Click on Change plan settings next to your selected power plan and in the following window, click on Change advanced power settings.  In the Advanced settings window, expand 'Enable adaptive brightness' and set it to Off.  Click Apply and Ok to save the setting, the restart the PC.
    If you can't locate the option in the Advanced power options menu, you can always disable the service responsible for this as shown in the video below.

  • Iphone 6 screen brightness problem

    hello everybody, i have iphone 6 which i am using now for 2 and half months. just from 1 week ago my iPhone 6 screen suddenly goes dim when I'm using it in strong sunny light. i always set my auto brightness on and when i use my phone in sunny light at roof first it gives clear and bright display then suddenly screen goes dim and when i try to maximise brightness level nothing happens it still remains dim and i notice my screen becomes very warm .. then i turn off my phone for few minutes and turn it on the screen brightness again works fine...and auto brightness also works normal..i have noticed this problem 2,3 times whenever i use it in sunny light at the roof..plz give me any suggestion....
      iphone 6, 64 gb model iOS version 8.1.2

    It's a google maps app setting. I agree, it is highly annoying and I have no idea why they put that setting into the app without the option to change it. I did a 600 mile trip with google maps and the auto screen dimming feature was awful.

  • T440 Display Brightness Not Working

    After the first time I put my piece of crap T440 to sleep, the keyboard keys for changing screen brightness stop working - no effect, & no on-screen desplay. Given the generally horrible feature set of this machine, I am not too surprised. I downloade & installed the power management program, the pm driver, the on-screen display driver, and a box of chocolates. Anybody got any ideas?

  • Flashcards for screen brightness no longer work after BIOS upgrade

    I have a Toshiba Satellite T135D/1320S laptop, and last night I upgraded the BIOS to v1.90 under the recently released recall notice.  AFter installing the BIOS, however, the Flashcard brightness controls no longer work. Whenever I press FN-6 or FN-7, the screen brightness Flashcard pops up and the toggle on the slider bar moves back and forth, but the brightness of the screen does not change.
    I have disabled and re-enabled the Flashcards as suggested in a separate forum, and I've also downloaded the most recent display driver (AMD display driver v8.615).  Neither effort corrected the problem.
    Anyone have any other suggestions?

    Satellite T135D-S1320
    Sometimes it helps to reset the machine. With the battery and AC adapter removed, close the Power switch for half-a-minute. Re-attach those, press the Power button to turn the computer on, and then immediately press the F2 key while the Toshiba logo is displayed. Press F9 to restore the BIOS default settings, press F10, and then select Yes (Exit Saving Changes). The computer will restart.
    Another things to try is reinstalling the TVAP.

  • Screen brightness OSD not working after 7 clean install

    Hi all,
    I just did a clean install of Windows 7 on my T400. Initially, none of the OSDs were working (volume, led light, screen brightness). But, I found this thread--http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/On-Screen-Display-feature-no-longer-works-i...--and downloaded the Hotkey drivers. This brought back the volume and led OSDs, but not brightness. Additionally, for some reason now the screen does not get nearly as dim as it used to. 
    Am I missing something obvious? Thanks!

  • Screen brightness no longer works

    never mind... glitch in Windows. Closing the screen and reopening solved it.
    Originally I posted a question about why my screen brightness wasn't responding any more. The HP service responded to my Fn+ key strokes by showing the brightness bar on the screen, but it stayed on the minimum. After having the laptop (EliteBook 8570p) almost a year, it always has worked flawlessly. I also used it last weekend, even after having already rebooted after Windows updates (I have also looked at the updates and none of the descriptions came close to anything having to do with dimming the screen).

    Is Firewall turned off on both machines?

    Hope someone can help 

    Hello smarisig. I understand you are not able to control screen brightness from the keyboard on Windows 8. By chance, did you upgrade to Windows 8 from Windows 7? I have located an online forum that contains troubleshooting on this issue: http://thedailybuggle.com/forum/unable-control-screen-brightness-windows-8-a-200.html
    The person who posted the issue on this forum had upgraded from Windows 7 to Windows 8, and then this issue occurred. That is the reason I asked if this Windows 8 was upgraded. Regardless, follow the troubleshooting presented and it could resolve the issue for you. If not, let me know and I will continue to research the issue in the meantime. I'm only here to help!

  • I have recently upgraded from my iphone 5 to a new phone. My iphone 5 's touch screen does not work anymore. I need to backup my phone, but I can't do it on itunes without my password. Everything besides screen is ok. Is there a way around it? :(

    I have recently upgraded from my iphone 5 to a new phone. My iphone 5 's touch screen does not work anymore. I need to backup my phone, but I can't do it on itunes without my password. Everything besides the screen is completely fine-the screen will not recognize my finger anymore. I am not trying to fix the phone, but I need to have my contacts. The pictures have already synced, but I need my password to do a full backup. Unfortunately, I can't type in my password. Is there any way around it? If I take my phone to the apple store, will they be able to help me? I am not willing to replace the screen just to do this, however, so that is out of the question. 

    Someone else may have a workaround, but, as far as I know, if you cannot interact with the screen on the iPhone, there is no way to unlock it so you can get to your contacts.
    Were you saving them to iCloud by chance? If so, you can restore them to your new phone.

    This is a user to user support forum and not Apple employees so it is best to not post your email address in an open discussion group.
    Have you tried a reboot of the iPhone?  Hold both the power and home buttons until the apple logo appears and it restarts, ignoring the red slider if it appears.
    My iPhone went to full brightness all the time after updating to iOS 6.1.3.  A reboot seems to have helped make it work as it should.  Also check Settings > Brightness and Wallpaper and see how it is set, reduce the brightness level it is too bright for you.

When I change the brightness to zero and return to the first level of brightness it works briefly but then the screen starts to flicker brightness and quickly extinguished. It seems to be a bad contact, it would not be normal for a quality product that should have, he has less than two years of use. Not because of the bad use or crash.

    Hey everyone in Apple world!
    I figured out how to fix the flashing yellow screen problem that I've been having on my MBP!  Yessssss!!!
    I found this super handy website with the golden answer: http://support.apple.com/kb/HT1379
    I followed the instructions on this page and here's what I did:
    Resetting NVRAM / PRAM
    Shut down your Mac.
    Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.
    I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process.  Since I did that, my MBP boots up just like normal.  No flashing yellow screen anymore!!   
    (Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
    Let me know if this works for you!

    iMac G5 (iSight) with 10.4.11:  Screen always dimmed. Starts at full bright and a second later dimms and stays like that forever.  Brightness controls work normally under this circunstance.  Please help !!!
    Please don't tell me to adjust anything on the preferences, since I have tried all.  I think it may be anoter kind of problem, maybe hardware related or anything.
    I ran the Hardware repair DVD and everything was ok, but when the imac restarted the screen was very lit again, but when it went sleep, when it went awake again the screen got dimmed again.  Because of that I think that the problem could be software related, but who knows.  Excuse my english.

    I can't see another possible answer - the longer your machine is up, the more the power supply is stressed, it protects itself by dimming the screen to lower the draw on it.
