Brightness hotkey doesn't work on laptop asus k501ux [Ubuntu 16.04.1]
I have laptop asus k501ux, just installed ubuntu and it seems every key works except brightness controls, in my case it is Fn+F5 (up) and F6(down). any idea why is that happening and how to fix it?
Solution 1:
- Go to the terminal and open grub file
sudo gedit /etc/default/grub
- Find
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
and change to this
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=native acpi_osi="
- Update grub
sudo update-grub
- Restart and it's done
That worked on Asus k501ux laptop
