No backlight after reboot

Question asked by vladm97 on Feb 6, 2016

I have installed amd drivers on my laptop and since I rebooted it I have no backlight. I have tried adding acpi_backlight=vendor as a kernel parameter and using xbacklight -set xx but none of this worked. I have downloaded the official amd drivers for an ati 7470M graphics card on Ubuntu 14.04. I have no problem using external monitors.
