Hello People

I had installed Fedora 19 on my Lenovo Y480. Using graphical installation the backlight wasn’t work, after installation the backlight doesn’t work only during the start up and the login prompt, after that when KDE launched the backlight works fine. I want to ask you how make the backlight works when system is starting up?

Thanks for your help

Is the back light dim, or is it completely absent?

The backlight dim, when I used a lamp or a lantern the information can be watched

adjust brightness for Discrete NVDIA

echo 50 > /sys/class/backlight/acpi_video1/brightness

adjust brightness for Integrated

echo 55 > /sys/class/backlight/acpi_video0/brightness

you can add this to rc.local
