I just installed the new Ubuntu 17.10 on my work notebook and found out a very common problem with the ACPI. The brightness controls (F5 & F6) are not working...
The solution to the problem is:
- Open the Terminal and type:
sudo gedit /etc/default/grub
acpi_osi=Linuxto the GRUB_CMDLINE_LINUX item
- In the Terminal execute the following command:
- Reboot your notebook
That's it! 👻
