[Bug 573984] Re: Screen brightness can not be adjusted in Lucid with Intel Arrandale graphics

SOLVED (for my laptop at least - Acer Aspire 5740)
The trick was to add "acpi_osi=" (without the quotation marks) to the
GRUB parameters. Setting the parameter to an empty string means that no
OS is reported to the BIOS. By default acpi_osi is set to Windows NT. I
had previously tried "acpi_osi=Linux" but it didn't work, apparently it
had to be an empty string.
The brightness keys work now :-)
