How do I get the brightness control working on a Lenovo Yoga 13?
- by Viktor Ax
Brightness control doesn't work by default in Ubuntu 13.04.
Solution for 12.10 doesn't work, also as this
Any idea how to fix it?
Update:
After research I found how to change brightness manually. What need to do is to type in terminal:
echo 2000 | sudo tee /sys/class/backlight/intel_backlight/brightness
It will reduce brightness by half, but still would be good to find solution which will allow to use keyboard for changing brightness.
Update2:
Found solution, see below
