Title:
  systemd-backlight does not restore screen brightness after reboot

Status in systemd package in Ubuntu:
  Incomplete

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-backlight@:*intel_screen_backlight_*" shows:
  "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.
