Well, Previously I used Freya. it's working fine on my laptop. Now I have switched to Juno and Brightness controls are not working.
I Tried to Adjust the Brightness Even via Settings. But it's not working.
I Tried this Command.
ninja@ninja:~$ ls /sys/class/backlight/ acpi_video0 intel_backlight
And paste the Below Code under
Section "Device" Identifier "card0" Driver "intel" Option "Backlight" "intel_backlight" BusID "PCI:0:2:0" EndSection
Still, it's not working. I tried restarting multiple times.
