>> Hi,
>>
>> It seems, there are issues with backlight and brightness control on some
>> laptops (mostly the ones that support Windows 8): keys to increase/decrease
>> brightness are not working, etc.
>>
>> The issues seem to be fixed in kernel 3.12 and newer.
>>
>> Good news is, I have adapted these fixes and workarounds for the kernel
>> 3.10.x as well.
>>
>> So, if there are problems with backlight or brightness control on your
>> laptop with ROSA, here are the packages with kernel 3.10.25-nrj-desktop
>> with these fixes incorporated:
>>
>> i586:
>> http://abf-downloads.rosalinux.ru/spectre_personal/
>> container/1496369/i586/main/release/
>>
>> x86-64:
>> http://abf-downloads.rosalinux.ru/spectre_personal/
>> container/1496370/x86_64/main/release/
>>
>> Feel free to try them and please report back if there are any problems.
>>
>> So far, I have tested it on my ThinkPad x230 with ROSA Fresh R2 (KDE) -
>> and yes, I can finally increase and decrease brightness with Fn+F8/F9! At
>> long last.
>>
>> Note that if function keys to manage brightness still do not work when
>> that kernel is used, try setting kernel option video.use_native_backlight=1
>> at boot time. It is needed for some Lenovo laptops at least.
>>
>> Important: do not use acpi* boot options with this kernel.
