followait:
systemd-backlight
Normaly a
acpi_backlight=video
In your kernelline should do the trick
Edited /etc/default/grub
as
GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor udev.log_priority=3 acpi_backlight=video"
not help
Open /etc/default/grub with sudo in nano or vi(m) for in a terminal.
For instance.
sudo nano -w /etc/default/grub
there should be a line similar to
GRUB_CMDLINE_LINUX_DEFAULT="quiet udev.log_priority=3"
Add line before the udev.log_priority so something like this
GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_backlight=video udev.log_priority=3"
Save your edit
with nano I thought it was with ctrl+o
and close with ctrl+x
with vi(m) ctrl+x
next update grub
sudo grub-mkconfig -o /boot/grub/grub.cfg
If no errors reboot
check if it works
