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 usr/share/X11/xorg.conf.d/20-intel.conf

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.
