Ubuntu – Screen Brightness not adjustable for Acer Aspire S3

11.10acerbrightnessscreen

First of all, thank you very much for providing this useful forum.
Too bad for me, there is no support for the Acer Aspire S3 yet (just came out in October)

Short Description of the Problem:
I cannot adjust the screen brightness. Neither Compiz nor the FN Key combination work.
Also the fan keeps running on full power. As you can guess, both of these drain my battery.

The Setup:
Acer Aspire S3, Intel i5 newest Generation, Intel HD3000 Grafic Accelerator (no driver maybe?)

Thanks in advance,

Hi I've had the same computer since two days ago. To be able to set the brightness, I've modified the line:

GRUB_CMDLINE_LINUX=""

to this:

GRUB_CMDLINE_LINUX="quiet splash acpi_osi=Linux acpi_backlight=vendor"

in the file /etc/default/grub, then:

sudo update-grub

Now I can set the brightness with the hotkeys, you can go so low that the screen is completely black... I just have a problem when the screen goes to sleep; I can't get it back. (I have to close the screen to put the computer in sleep and reopen it...)

Have you found a way to get the touchpad scrolling functional? And did you find the solution to set the fan speed?

Except for those little thinks it's a great thin, light and responsive laptop. I really hope those problems will be fixed soon.
