Backlight sometimes gives problem due to grub misconfiguration. You need to edit the grub and edit it. Here is what you have to do.

As root edit /etc/default/grub
Change the line GRUB_CMDLINE_LINUX="" to GRUB_CMDLINE_LINUX="acpi_osi=Linux" save the file and then sudo update-grub and reboot.

That will solve your problem.
