    ask for help about "thinkpad_acpi:unsuported brightness interface"

    every body:
         hi! I need your help.
         when I installed ubuntu 14.04 (64bits) via usb flash disk ,I had to set "acpi=off" and  "noacpi".
    but when the system was install successfully,I found I couldn't shutdown the ubuntu with command
    "sudo shutdown -h now" or click the shutdown button on my desktop.it freezed on the picture with
    purple backgroud and some splashes on it . but it worked fine when I just reboot the system . for all
    I kown ,the the acpi is important for sytem to manage the power. If I shutdown the acpi function,I need
    to press the power button every time when I want to shutdown the computer ; and the lack of acpi function
    may harm my hadware.
       I use thinkpad E425, and  I have try add "acpi_osi=linux" ,"acpi=ht","thinkpad_acpi.brightness_enable=1",
    but none of thems worked.
       any idea to solve the problem? thanks a lot.
    bheis

    Support for EC version in newer Thinkpads

    Hello,
    I'm sorry for my bad english..
    I have a Thinkpad T430 and i see that the driver doesn't find the EC
    version for my laptop so it doesn't enable some features (like thermal
    sensors).
    I have found that T430 doesn't have an EC version string in OEM DMI
    strings, but it has a major and minor version number of the EC in record
    0 (BIOS type) of DMI (like 2.8 SMBIOS specifications
    http://dmtf.org/sites/default/files/standards/documents/DSP0134_2.8.0.pdf ).
    I think that, maybe, we can change the way with which driver obtains
    BIOS and EC version, simply catching them from record 0 (BIOS) of DMI,
    in particular from BIOS Version,Embedded Controller Firmware Major
    Release, Embedded Controller Firmware Minor Release strings and not from
    OEM strings, that they are not complete in new Thinkpads.
    I have written a kernel patch to enable kernel API to return Embedded
    Controller Firmware Release fields and, maybe, i could send it to kernel
    mantainers.
    Otherwise, maybe, it's possible to obtain Embedded Controller Firmware
    Version directly from EC, when we are sure that the laptop is a
    Thinkpad, because they are presented in some EC registers.
    Thank you

    Fixing the mute button on SL410

    Right now the mute button on the SL410 doesn't work properly. In order for the sound to be muted you need to
    press the mute button followed by one of the volume buttons (see
    https://bugs.launchpad.net/ubuntu/+source/linux/+bug/994274). But changing the keymap as
    follows fixes the issue.
    
     <at>  <at>  -3157,7 +3157,7  <at>  <at>  static int __init hotkey_init(struct ibm_init_struct *iibm)
                     */
                    KEY_RESERVED,   /* 0x14: VOLUME UP */
                    KEY_RESERVED,   /* 0x15: VOLUME DOWN */
    -               KEY_RESERVED,   /* 0x16: MUTE */
    +               KEY_MUTE,       /* 0x16: MUTE */
    
                    KEY_VENDOR,     /* 0x17: Thinkpad/AccessIBM/Lenovo */
    
    The LED still doesn't work, but hey, at least mute works. The comments above it says that the "firmware may
    react very differently" if the keymap is changed. So is it okay to change the keymap? Would there be any side effects?

    ACPI problem with Lenovo x230

    Hi.

    I found that my brightness control does not work very well on linux.
    One time I found this message in my logs so I'm just writting.

    Should I fill bug report?
    If you are interested I can test new versions of the module and do more tests.

    All best,
    Tomasz Czyż

    What information would you like?  I have the Lenovo Twist, just upgraded 
    to Ubuntu 14.04.  I ran 12.04 on it for a year, ACPI was always a 
    problem.  It works as long as I never let it enter sleep mode on 
    battery, or operate on batter for too long.  So I always plug in and it 
    always works reliably.
    
    I would be willing to send more information, just let me know what you need.
