I have an Asus VivoBook X513EA Intel i3-1115G4 UHD Graphics and brightness can't be adjusted (it stays at 100%).

sudo lspci -knn | grep -A6 VGA

0000:00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:9a78] (rev 01)
	Subsystem: ASUSTeK Computer Inc. Device [1043:1432]
	Kernel driver in use: i915
	Kernel modules: i915

	Kernel driver in use: proc_thermal
	Kernel modules: processor_thermal_device

Update:
Deepin 20.2.2 and Linux Lite 5.6 are also unable to adjust the brightness.

Thanks.

Which DE? Try this (convert to xzm, put it inside modules folder and reboot).
