Re: Sony Vaio SVF15AA1QM keyboard lighting working erratically
I only use Vaios (have 9 or 10 of them, oldest since 1997), and they all still work, with linux.
The ones I have with backlit keyboard , Vaio Z, and Vaio T , do light up their keyboards, but it happens independently of OS, and only when there is low light. i.e. if I type during the day the backlight does not turn on. They appear to have a light sensor.
I have not found any entry in Linux to change any backlight setting.
