bruno pennec, typically bugs are considered fixed when no WORKAROUNDs are required to have the desired functionality. However, if this works for you, and you would not like anyone to continue to investigate the issue as it is in 14.10, please feel free to mark this Status Invalid at the top of the bug report.

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/backlight/acpi_vgaX/actual_brightness had the right value (in the 2 directory) - changing /sys/class/backlight/acpi_vgaX/brightness change actual_brightness but had no effect on screen too 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_.PCI0.VGA_.AF03] (Node ffff8801a665c000), AE_AML_INFINITE_LOOP (20120711/psparse-536) [ 30.212214] ACPI Error: Method parse/execution failed [\_SB_.PCI0.VGA_.ATIF] (Node ffff8801a665ad98), AE_AML_INFINITE_LOOP (20120711/psparse-536) 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.PB3_.VGA_.LCD_._BCL correctly acquired and released locks 5 times. Test 89 of 94: Check _BCM (Set Brightness Level).

WORKAROUND: Use the open source radeon driver.
