Bug Description
As the title says, on this laptop the brightness controls are NOT saved after reboot.
What is saved instead, is only the keyboard brightness.
I have tested two distros, Ubuntu 18.04.2 LTS and 19.04, happens on both systems. But there is a difference
On 19.04, "systemctl status systemd-
"Saved brightness 20 too low, increasing to 75"
On 18.04.2 does not show anything rather than the service starting normally
The laptop is a Dell XPS 15 9550, the screen backlight driver is the intel one.
