Yes kaihengfeng. Now, my GRUB_CMDLINE_LINUX_DEFAULT="acpi_osi=Linux acpi_backlight=vendor" and /sys/class/backlight still empty. Today I've updated the laptop and the kernel is 4.13.0-38-generic and the problem still happening.

I hope in this week, I can change my kernel to test this solution. Thanks kaihengfeng.
