SOLVED
Do
Code: Select all
sudo nano /etc/default/grub
Code: Select all
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash'"
Code: Select all
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor acpi_osi='!Windows 2013' acpi_osi='!Windows 2012'"
Code: Select all
sudo update-grub
Code: Select all
modprobe snd_hda_intel
Code: Select all
systemctl reboot
Reboot again. (That's just what other instructions say, and it worked for me. Will it work with one reboot? I have not tried)
That worked for me!
