What is the problem called acpi_video0 error in linux brightness?
Actually i replaced my laptop with new MB from AMD A8-6410 to A6-6310. it actually died. the new one working fine but the problem is i can't control my brightness in any operating system i through at it. i dual boot ubuntu and win10. i installed the latest drivers from the amd for my chip.
brightness isn't controllable tried every possible solution..
i think can the brightness problem comes when the connections between the screen and the MB(motherboard).
can anyone clarify my doubt about this..
what's the problem with this MB ..
