Bug Description

== SRU Justification ==

Impact:
Buggy ACPI table causes brightness unable to be adjusted, which means
certification testing also fails.

Fix:
Quirk this model so that it no longer follows the Win8 AML path.

Testcase:
Test brightness adjustment on the machine. Already verified by test
kernel on LP#1231305.

--------

CID: 201304-13196 Dell Inspiron 5537

Unable to adjust the screen brightness on this system.
Tested with 3.8.0-29 and 3.8.0-30 kernel.

Step:
1. Install 12.04.3 and boot to desktop.
2. Try to adjust brightness with the brightness keys.
2. Try to adjust brightness in "Brightness and Lock" of System settings.

Expected result:
Brightness could be adjusted by using the brightness keys and by adjusting in "Brightness and Lock" of System settings.

Actual result:
1. Brightness keys events (keycode 224/225) were captured, but the brightness cannot be adjusted. Brightness level indiciator only changes between Max and Max - 1
2. Brightness cannot be adjusted in "Brightness and Lock" of System settings.

Disabling the ACPI backlight driver with "acpi_backlight=vendor" could make it work, but it also cause the touchpad and keyboard stop working.

Also verified with the latest mainline kernel 3.12rc2, the brightness level indicator could be changed from 0 - Max correctly by pressing the brightness keys, but the brightness still not changing.

Looks like the BIOS is flawed when it's running the win8 path.

Can you add the acpi_osi=\"!Windows 2012\" to the grub command line when booting the 3.8 kernel and see if the problem still exists? You can do that by adding acpi_osi=\"!Windows 2012\" to the variable "GRUB_CMDLINE_LINUX_DEFAULT" in /etc/default/grub:

e.g:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=\"!Windows 2012\""

Then run "sudo update-grub".

Hello Anthony,

The brightness could be adjusted by the hotkey and in system settings with acpi_osi=\"!Windows 2012\" added into grub.

Hello Anthony,

Verified with the deb files you provided, and without acpi_osi=\"!Windows 2012\" in grub
And the hotkey works, it can also be adjusted in system settings.
Thanks!

For the record, adding acpi_osi=\"!Windows 2012\" to grub command-line fixes the same problem on my HP ProBook 430 G1 with similar but slightly different VGA chipset (Intel Corporation Haswell-ULT Integrated Graphics Controller [8086:0a16]). Haven't tried the deb provided by Anthony in comment #31, but I don't suppose they would work, as the fix in blacklist.c seems to be vendor/product specific.

Could this be a more generic Haswell issue?

Attaching dmidecode and lspcpi on my HP 430 G1 system.

On saucy, the brightness hotkey could change the brightness level indicator, but the brightness cannot be changed

However, the brightness control works fine after -proposed
