Hello, I am using 3.8.0.26 on Kubuntu 13.04 (KDE) Samsung Laptop and currently using "acpi_osi=Linux acpi_backlight=vendor" to enable backlight control. Whenever I log off, the controls are disabled again and I need to run intel_backlight. Another problem is power profiling. Whatever I set dimming and/or backlight off durations. It automatically turns it off in 5 minutes (even I totally disable it).
