    Acer Aspire S3

    I just installed fedora 16 on my new Acer Aspire S3 notebook. Couple of problems I am facing are -
    1. I am not able to control the brightness
    2. The fan does not stop. I hear it running all the time
    3. The touchpad is very slow and there is no option to change it


    I can live with the fan running but the brightness is really bothering me. External mouse works great so I can live without the touchpad too. Earlier I found a solution but it is for ubuntu

    The grub file looks different from ubuntu so I was wondering if anyone has a solution to this issue

    Re: Acer Aspire S3

    You should have an /etc/default/grub, and it probably has the line

    GRUB_CMDLINE_LINUX="quiet rhgb"

    Add most of what they give there, (the splash is for a splash screen which you don't need, and quiet is there.

    So you change what I had above to read

    GRUB_CMDLINE="quiet rhgb pcie_aspm=force i915.i915_enable_rc6=1 acpi_osi=Linux acpi_backlight=vendor"

    As far as I know, you shouldn't need a second line saying pcie_aspm force, as you already added it.

    Then, the Fedora command is somewhat different. Instead of the update-grub, run


    grub2-mkconfig -o /boot/grub2/grub.cfg

    as root or using sudo, i.e., sudo grub2-mkconfig -o /boot/grub2/grub.cfg

    Thanks smr54! That worked great.

    I changed it from
    GRUB_CMDLINE_LINUX="rd.md=0 rd.dm=0 KEYTABLE=us quiet SYSFONT=latarcyrheb-sun16 rhgb rd.luks=0 LANG=en_US.UTF-8 rd.lvm.lv=vg_xxxxxx/lv_swap rd.lvm.lv=vg_xxxxxx/lv_root"

    To

    GRUB_CMDLINE_LINUX="rd.md=0 rd.dm=0 KEYTABLE=us quiet SYSFONT=latarcyrheb-sun16 rhgb pcie_aspm=force i915.i915_enable_rc6=1 acpi_osi=Linux acpi_backlight=vendor rd.luks=0 LANG=en_US.UTF-8 rd.lvm.lv=vg_xxxxxx/lv_swap rd.lvm.lv=vg_xxxxxx/lv_root"

    Then the command

    # grub2-mkconfig -o /boot/grub2/grub.cfg

    It works after rebooting the box!
