Bug Description
Backlight keys work (I get the slider on screen) , but there is no change on brightness.
Other tests :
- kernel 3.6.5 (ppa) gives same result than kernel 3.5.0-17 (default 12.10 configuration)
- when Backlight is set to a new value(on the slider), a sleep and a wake up set the correct value on screen brightness
- L850D-11Z is a dual GPU (AMD A8), so I take a look at acpi tree :
- there is 2 directory acpi_vga0 and acpi_vga1 for the 2 radeon GPU
- /sys/class/
- changing /sys/class/
From the log :
On dmesg, i have this 2 errors, but they don't seem to be related to backlight variable _BCL :
[ 30.212195] ACPI Error: Method parse/execution failed [\_SB_.
[ 30.212214] ACPI Error: Method parse/execution failed [\_SB_.
I do the standard reports on acpi, and get the following result :
In result.log :
PASSED: Test 88, Method _BCL returned a sane package of 10 integers.
PASSED: Test 88, \_SB_.PCI0.
Test 89 of 94: Check _BCM (Set Brightness Level).
ACPICA Exception AE_AML_
FAILED [CRITICAL] AEAMLPackgeLimit: Test 89, Detected error 'Package limit' when evaluating
'\_SB_.
PASSED: Test 89, \_SB_.PCI0.
ACPICA Exception AE_AML_
FAILED [CRITICAL] AEAMLPackgeLimit: Test 89, Detected error 'Package limit' when evaluating
'\_SB_.
PASSED: Test 89, \_SB_.PCI0.
ACPICA Exception AE_AML_
FAILED [CRITICAL] AEAMLPackgeLimit: Test 89, Detected error 'Package limit' when evaluating
'\_SB_.
PASSED: Test 89, \_SB_.PCI0.
So i join DSDT.dsl to this report. I would add result.log if it is needed.
WORKAROUND: Use the open source radeon driver.

bruno pennec, thank you for reporting this and helping make Ubuntu better.
What key combination specifically toggles the brightness?
As well, could you please test the latest upstream kernel available following https:/ /wiki.ubuntu. com/KernelMainl ineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: fixed-upstream fixed-upstream- VERSION- NUMBER
kernel-
kernel-
where VERSION-NUMBER is the version number of the kernel you tested. For example: fixed-upstream- v3.7-rc4- raring
kernel-
This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: testing
needs-upstream-
If the mainline kernel does not fix this bug, please add the following tags: bug-exists- upstream bug-exists- upstream- VERSION- NUMBER
kernel-
kernel-
As well, please remove the tag: testing
needs-upstream-
If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: unable- to-test- upstream unable- to-test- upstream- VERSION- NUMBER
kernel-

Please let us know your results. Thank you for your understanding.
